2. Attach the DB-9 female cable to the male DB-9 serial port on the Managed Media Converter.
3. Attach the other end of the serial cable to an ASCII terminal emulator. For example, Windows98/2000/XP HyperTerminal utility.
   The RC-2201 converter uses the following serial port parameter values:
   
   Baud rate: 57600
   Stop bits: 1
   Data bits: 8
   Parity: N
   Flow control: none
   
   
4. When the terminal emulator is connected to the RC-2201, press the key, the login prompt will now be shown on the screen. The default username and password is shown below:
   
   Username: admin
   Password: admin
   
   
5. Please refer to Section 4-1 Console Management for details about console user interface operating description.

1. Attach a Cat. 5 TP cable between your PC and the TP port of the RC-2201 converter.
2. Boot up the converter.
3. Either run a terminal simulator and invoke a telnet session on your PC, or run your browser software.

1. Attach the fibre connector to the Managed Media Converter.
2. Attach the other end of cable to the Central Media Converter Chassis.
3. At central site:
   • Install and connect a PC to the TP port of the Central Media Converter Chassis with Cat. 5 UTP network cable (or via a switch).
   • Assign a public or private IP address in accordance with each network site. Please refer to Fig. 2-10 about the Managed Media converter default IP address information.

Note:

1. For IP address assignment, there is a simple rule that exists and must be obeyed. Basically, the Internet addresses are categorized into class A, B and C. The IP addresses for Class A are those less than 126.255.255.255 The IP addresses for Class B are ranged from 128.0.0.0 – 191.255.255.255 The IP addresses for Class C are ranged from 192.0.0.0 – 223.255.255.255 The rest of the IP addresses are for multicast and broadcast.
2. The subnet mask is used to separate the host addresses from the network addresses. For example, there are 255 IP addresses in a class C network, but they are considered as a single network. When we want to have more than two independent networks in an office, a partition to the network must be performed. In this case, a subnet mask must be applied.
3. Private IP address, IANA (Internet Assigned Numbers Authority) has reserved three blocks of IP address for private networks:
   
   Class A: 10.0.0.0 --- 10.255.255.255
   Class B: 172.16.0.0 --- 172.31.255.255
   Class C: 192.168.0.0 --- 192.168.255.255

Please refer to RFC 1597 and RFC 1466 for more information.

CHAPTER 3. Operation of Web-based Management

1. The RC-2201 converter provides a built in web server for easy administration and monitoring. The converter can be managed via the copper or the fibre interface. If you need to change the default IP address for first use, then you will need to use the console to modify the IP address. Please refer to Chapter 4 for more details.
   
   The default values for the RC-2201 Converter are as follows:
   IP Address: 192.168.1.1
   Subnet Mask: 255.255.255.0
   Default Gateway: 192.168.1.254
   Username: admin
   Password: admin
   
   
2. Once you have configured the IP address accordingly you can now open up a web browser and enter the devices IP address. For instance, http://192.168.1.1, you will now be prompted for a username and password, enter the username and password as above.

Port Configuration

Function description:

Changes the state and configuration of each port.

Parameter description:

Port:

The TP Port is the RC-2201's Ethernet UTP Interface. The Fibre Port is the RC-2201's Ethernet Fibre Interface.

State:

Shows if the communication capabilities of the port is Enabled or Disabled. When Enabled, traffic can be transmitted and received via this port. When Disabled, the port is blocked and no traffic can be transferred through this port. The Port State is configured by the user. There are only two states available Enable and Disable. If the ports state is set to Disabled, then that port is prohibited from passing any traffic, even if it has link. The default value is Enabled.

Auto Negotiation:

Two states can be chosen, Enable and Disable. Enable means the port will use the auto-negotiation algorithm to exchange the speed, duplex and flow control settings with the linked partner. When enabled, the speed, duplex mode and flow control settings may change. Disable means that forced mode will be used. When disabled, if you want to set up a connection successfully, the port configuration should be the same for the local port and the linked partner. If their configuration is different, link between the two devices may not be established. The RC-2201, fibre port supports forced mode only.

Speed/Duplex:

Is used to set the speed and duplex settings. The copper port can either run at 10Mbps, 100Mbps or 1000Mbps and can run at half or full duplex. The fibre port can only run at 1000Mbps and can also run at half or full duplex.

Flow Control:

There are two modes that can be chosen, Enable and Disable. If flow control is set to Enable, both parties can send PAUSE frames to the transmitting device if the receiving port is to busy to handle the requests. When set to Disable, flow control will not exist on that port and if the port is to busy to handle the request the packet will be dropped. Default: Enable

3.3.1 System Configuration

There are six functions contained in the System Configuration function folder. They are Username/Password Setting, IP Configuration, System Time Setting, Location/Contact Setting, TP Port Management and Power Down Setting.

3.3.1.1 Username / Password Setting

Function name:

Username/Password Setting

Function description:

Only the administrator can create, modify or delete the username and password. The administrator can modify other guest identities passwords without having to confirm the password, but when modifying the administrator password the password must be confirmed. The guest-equivalent identity can only modify his own password. Please note that you must confirm the administrator/guest identity by ticking the check box prior to changing the username and password.
Default settings are as follows:

Username: admin
Password: admin

3.3.1.2 IP Configuration

The IP configuration is one of the most important configurations in the RC-2201. Without the correct settings the network manager will not be able to see the device. The RC-2201 supports both manual IP address setting and automatic IP address setting via a DHCP Server. When the IP address is changed you must reboot the converter for the setting to take effect.

Function name:

IP Configuration

Function description:

Set IP address, subnet mask, default gateway and DNS for the RC-2201.

Parameter description:

DHCP:

The RC-2201 supports DHCP client mode, which allows the converter to obtain an IP address automatically if this function is set to Enable. The RC-2201 will find the DHCP server on the network and request an IP address. If there is no DHCP server available on the network the RC-2201 will count down from 60 seconds, if the DHCP server still does not respond the RC-2201 will use it's last pre-configured IP address. If this function is set to Disable, you will have to set an IP address manually. Default: Disable

IP Address:

If the DHCP function is set to Disable the user can configure the IP settings for the converter. Default: 192.168.1.1

Subnet Mask:

Set the subnet mask to a value corresponding to your current network settings. Default: 255.255.255.0

Default Gateway:

Set an IP address for a gateway to handle those packets that do not meet the rules predefined in a device. If a packet does not meet the criteria for other routers, then it must be sent to a default router. This means any packet with undefined TCP/IP information will be sent to this device unconditionally. Default: 192.168.1.254

DNS:

Set an IP address for a Domain Name Server. The RC-2201 DNS client program will ask the Domain Name Server to resolve the IP address of the named host. To select the "Manual" for fixed DNS IP address setting. To select "Auto" the DNS IP address will be assigned from DHCP server. The default DNS setting is empty. Default: DNS : 0.0.0.0

3.3.1.3 System Time Setting

The RC-2201 provides manual and automatic ways to set the system time via NTP. Manual setting is simple, you just input the "Year", "Month", "Day", "Hour", "Minute" and "Second" within the valid value range indicated in each item. If you input an invalid value, for example, 61 in minute, the converter will change the value to 59.

NTP is a well known protocol used to synchronise the clock of the RC-2201 system time over a network. NTP, an internet draft standard formalised in RFC 1305, has been adopted on the system version 3 protocol. The RC-2201 provides four built-in real internet site NTP server IP addresses and a user-defined NTP server IP address. The time zone is Greenwich-centered which uses the expression form of GMT +/- xx hours.

Function name:

System Time Setting

Function description:

Set the system time manually or get the network time from a NTP server for system time reference in the RC-2201.

Parameter description:

Manual:

The user can key in the Year, Month, Day, Hour, Minute and Second directly to synchronise the system time with the local time. Default: Year=2000, Month=1, Day=1, Hour=0, Minute=0 Second=0

NTP:

Select the NTP protocol to synchronise the system time, you will only need to choose a NTP server and select a Time Zone. Then, click the Apply button, the system will take effect immediately. This will not automatically update the system time periodically.

3.3.1.4 Location/Contact Setting

Function name:

Location/Contact Setting

Function description:

The Location and Contact fields can be filled in with some useful information for the network managers reference. The location field can contain the devices location information. Thus, the device maintainer can easily find the device. The contact field can contain the devices maintainer information e.g. name, phone number, etc..

Parameter description:

Location:

The location field can contain the devices location information with any visual characters. The default setting is empty. User-defined.

Contact:

The contact field can contain the devices maintainer information with any visual characters. The default setting is empty. User-defined.

3.3.1.5 TP Port Management

Function name:

TP Port Management

Function description:

The TP Port Management function is used to disable the use of management through the TP Port. When disabled Administrators will no longer be able to manage the device through the TP Port.

Parameter description:

Disable:

To isolate traffic from the managed RC-2201 requests from TP port when the TP port management is set to "Disabled".

Enable:

Allows traffic to pass with the managed RC-2201 request from the TP port when the TP port management is set to "Enabled". Default: Enable

3.3.1.6 Power Down Setting

Function name:

Power Down Setting

Function description:

This function is designed for safety reasons. It will detect two things: If the temperature is over 60 oC or if the cooling fan has failed. If these two conditions happen at the same time and the "Power Down Setting" is enabled, the RC-2201 will power down automatically.

Parameter description:

Disable:

The RC-2201 will not power down automatically, while the temperature is over 60 oC and the cooling fan has failed. If the two conditions happen at the same time and the "Power Down Setting" is disabled.

Enable:

The RC-2201 will power down automatically, while the temperature is over 60 oC and the cooling fan has failed. If the two conditions happen at the same time and the "Power Down Setting" is enabled.

3.3.2 SNMP Configuration

Function name:

SNMP Configuration

Function description:

Any network management station running the Simple Network Management Protocol (SNMP) can manage the converter which is equipped with an SNMP Agent, provided that the Management Information Base (MIB) is installed correctly on the management station. SNMP is a protocol that is used to govern the transfer of information between a SNMP Manager and Agent. The SNMP agent will only run on the converter if you have enabled SNMP. If disabled the related community name, trap host IP address, trap and RMON counters will be ignored.

In the SNMP Configuration function, the community string is used as a password to authenticate the request. If both devices have the same community name, then they can talk to each other; otherwise, the network management unit cannot access the converter via the SNMP protocol. To set up a trap host means to create a trap manager by assigning an IP address to receive the trap message. In other words, the trap host is a network management unit with a SNMP manager which receives the trap messages from the converter. You can configure up to 4 trap hosts to prevent important trap messages from being lost.

A SNMP manager must pass the authentication so that it can access the agent. So, both parties must have the same community name. You can also define the system name, system location and contact person for easy management via the SNMP manager. Fill in the data, then click the Apply button to apply the new settings.

Parameter description:

SNMP:

SNMP enable/disable selection. Default is Enable.

Get Community:

User-definable community name for the authentication of the SNMP Get Community, the default is public.

Set Community:

User-definable community name for the authentication of SNMP Set Community, the default is private.

Trap Host 1 IP Address:

To set up a trap host IP address in order to receive RC-2201’s trap messages. The default host 1 IP address 0.0.0.0 means that the transmission of trap message to host 1 is disabled.

Community (Host 1):

User-definable community name for the authentication of SNMP Trap community for host 1, the default is public.

Trap Host 2 IP Address:

This parameter setting is the same as Trap Host 1 IP Address.

Community (Host 2):

This parameter setting is the same as Community (Host 1). The default is public.

Trap Host 3 IP Address:

This parameter setting is the same as Trap Host 1 IP Address.

Community (Host 3):

This parameter setting is the same as Community (Host 1). The default is public.

Trap Host 4 IP Address:

This parameter setting is the same as Trap Host 1 IP Address.

Community (Host 4):

This parameter setting is the same as Community (Host 1). The default is public.

Cold Start Trap:

This trap packet will be sent while the RC-2201 Converter’s power is cycling.

Warm Start Trap:

This trap packet will be sent while rebooting the RC-2201 Converter by means of pressing the RC-2201’s RESET button or running Reboot function of software.

Link Down Trap:

This trap packet will be sent while the RC-2201 Converter’s UTP link status has changed from up to down. The Link Down Trap Packet will not be sent while the RC-2201 Converter’s fibre port link status has changed from up to down. The fibre port Link Down Event will be stored in the Log Data.

Link Up Trap:

This trap packet will be sent while the RC-2201 Converter’s UTP or Fibre port link status has changed from down to up.

Authentication Failure Trap:

This trap packet will be sent while the RC-2201 SNMP agent authentication failure occurs. Authentication failure means that the SNMP agent receives a SNMP request with an incorrect community name.

3.3.3 Packet Length Setting

The RC-2201 provides two levels of Ethernet frame size for the user to configure. One is 1536 bytes and the other is 1522 bytes. After selecting one of these two options and then pressing the Apply button, the setting will take effect immediately. Default setting is 1522 bytes long which will accommodate the size of the tagged VLAN frame.

3.3.4 Broadcasting Suppression

Function name:

Broadcasting Suppression

Function description:

The Broadcasting Suppression function is used to spread the request of broadcast packets into a larger time frame to prevent traffic congestion due to broadcast packets from multiple network devices trying to connect to NMS, boot servers or DHCP servers.

The RC-2201 supports a random delay time for DHCP and boot delay for each device. This suppresses the broadcast storm when all devices are at booting stage at the same time. The maximum user-defined delay time is 30 sec. If the Broadcasting Suppression function is enabled, the delay time is set randomly, ranging from 0 to 30 seconds, because the exact delay time is computed by the converter itself. The default is “Disable”.

3.3.5 Misc. Feature Configuration

The Miscellaneous Feature Configuration gathers many functions, including MAC Address Aging Time Setting, Broadcast Storm Filter Limit, Priority Queue Service, Max. bridge transmit delay bound control and QoS Policy. They are described below.

Function name:

MAC Address Aging Time Setting

Function description:

This function is used to set the MAC Address Age-out Time applied to the whole MAC address table except some static MAC address. The range of MAC table address entry age-out time is from 30, 33, 36,…765 seconds. If a source node has not visited the converter for a time longer than the Age-out Time, its responded MAC address information in the converter's MAC table will be marked invalid by the converter's aging function. This age-out rule will not be applied to the static MAC addresses.
The default age-out time is 300 seconds.

Function name:

Broadcast Storm Filter Limit

Function description:

The Broadcast Storm Filter Limit is applied to filter the converter's broadcast traffic. If you choose an upper threshold, it is enabled. It is a global function. The setting will be applied to all ports of the converter. The threshold is the percentage of the port's total bandwidth used by broadcast traffic. When broadcast traffic for a port rises above the threshold you set, broadcast storm filter discards the extra broadcast traffic. This keeps the total broadcast traffic less than the threshold able to be forwarded and limits too many broadcast packets running over the network. The RC-2201 supports five threshold values, including 5%, 10%, 15%, 20%, and 25%.
Default is OFF.

Function name:

Priority Queue Service

Function description:

The RC-2201 provides three priority queue services for transmission scheduling, including FCFS, strict priority and WRR. It is a global function.
First Come First Service (FCFS): All incoming packets will be sent out upon the sequence of packet's arrival order.

All High before Low: After all high priority packets are sent out, then low ones are sent in turn.

Weighted Round Robin (WRR): This is actually a transmission ratio of high priority packets and low priority packets. If you would like to repeatedly send 5 high priority packets first and then 2 low priority packets. You can set a 5 to high weight field and a 2 to low weight field in WRR function row.
The WRR Default Setting High = 2, Low = 1

Function name:

Max. bridge transmit delay bound control

Parameter description:

Max. bridge transmit delay bound control

The function "Maximum bridge transmit delay bound control" is applied to limit the maximum queuing time of the packets in the converter. If enabled, the packets queued over the time set will be dropped. Valid values are 1 sec., 2 sec., 4 sec. and OFF.
Default value is OFF.

Enable Delay Bound:

Limit the resided time of the low priority packets in the converter. If the low priority packet is not transmitted out and time set by "Delay bound" is enabled, the packet will be dropped. The valid delay time is 1 - 255 ms and OFF.
Default Max. Delay Time is 1ms.

Note:
Make sure that "Max. bridge transmit delay bound control" is enabled before enabling Delay Bound, because Enable Delay Bound will only work when "Max. bridge transmit delay bound control is enabled".

Function name:

QoS Policy

Function description:

It is used to assign which priority level is high or low. Normally, we map the priority levels 7 - 4 to be high priority and the priority levels 3 - 0 to be low priority. The mapped priority will be applied to the forwarding scheduler. In the RC-2201, it is FCFS, Strict and WRR. The QoS policy is global.
Default: If enabled, priority levels 7 - 4 are assigned to be high priority, and priority levels 3 - 0 are assigned to be low priority.

3.3.6 Spanning Tree Configuration

The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, ensure that only one path is active between any two nodes on the network at a time. User can enable Spanning Tree Protocol on converter's web management and then set up other advanced items. We recommend that you enable STP on all converters to ensure a single active path on the network.

3.3.6.1 STP Status

Function name:

STP Status

Function description:

In the Spanning Tree Status, the user can read 12 parameters about the STP current status. The 12 parameters are described in the list below:

Parameter description:

Shows the root bridge ID of this network segment. If this converter is a root bridge, the "Designated Root" will show this converter's bridge ID.

Designated Priority:

Shows the current root bridge priority.

Root Port:

Shows the port number connected to the root bridge with the lowest path cost.

Root Path Cost:

Shows the path cost between the root port and the designated port of the root bridge.

Current Max. Age:

Shows the current root bridge maximum age time. Maximum age time is used to monitor if STP topology needs to change. When a bridge does not receive a hello message from root bridge until the maximum age time is counted down to 0, the bridge will treat the root bridge as malfunctioned and issue a Topology Change Notification (TCN) BPDU to all other bridges. All bridges in the LAN will re-learn and determine which the root bridge is. Maximum Age time is assigned by the root bridge in units of seconds. Default is 20 seconds.

Current Forward Delay:

Shows the current root bridge forward delay time. The value of the Forward Delay time is set by the root. The Forward Delay time is defined as the time spent changing from a Listening state to a Learning state or from a Learning state to a Forwarding state of a port in a bridge.

Hello Time:

Shows the current hello time of the root bridge. The Hello time is a time interval specified by the root bridge, used to request all other bridges periodically sending a hello message every "hello time" second to the bridge attached to its designated port.

Topology Change Count:

STP Topology Change Count expresses the time spent in units of seconds since the beginning of the Spanning Tree Topology Change to the end of the STP convergence. Once the STP change is converged, the Topology Change count will be reset to 0. The figures showing in the screen may not be the exact time it spent but very close to, because the time is eclipsing.

Time Since Last Topology Change:

Time Since Last Topology Change is the accumulated time in units of seconds the STP has been since the last STP Topology Change was made. When a Topology Change is initiated again, the counter will be reset to 0. And it will also count again once STP topology Change is completed.

3.3.6.2 STP Configuration

The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning Tree Configuration, there are six parameters open for the user to configure. Each parameter description is listed below.

Function name:

STP State Setting

Function description:

The user can set the following Spanning Tree parameters to control the STP function enable/disable, select which mode RSTP/STP and allow the STP state machine behavior to send BPDU in this converter. The default setting of Spanning Tree Protocol is "Disable".

Parameter description:

Spanning Tree Protocol:

Set 802.1W Rapid STP function Enable / Disable. Default is "Disable"

Bridge Priority:

The lower the bridge priority is, the higher priority it has. Usually, the bridge with the highest bridge priority is the root. If you want to have the RC-2201 as the root bridge, you can set this value lower than that of a bridge in the LAN. The valid value is 0 ~ 61440. The default is 32768.

Hello Time:

Hello Time is used to determine the periodic time to send normal BPDU from designated ports among bridges. It decides how long a bridge should send this message to other bridges to tell them I am alive. When the RC-2201 is the root bridge of a LAN, for example, all other bridges will use the hello time assigned by the RC-2201 to communicate with each other. The valid value is 1 ~ 10 in units of seconds.
Default is 2 seconds.

Max. Age:

When the RC-2201 is the root bridge, the whole LAN will apply this figure set by the RC-2201 as their maximum age time. When a bridge receives a BPDU originated from the root bridge and if the message age conveyed in the BPDU exceeds the Max. Age of the root bridge, the bridge will treat the root bridge as malfunctioned and issue a Topology Change Notification (TCN) BPDU to all other bridges. All bridges in the LAN will re-calculate and determine who the root bridge is. The valid value of Max. Age is 6 ~ 40 seconds.
Default is 20 seconds.

Forward Delay:

You can set the root bridge forward delay time. This figure is set by the root bridge only. The forward delay time is defined as the time spent changing from a Listening state to a Learning state and also from a Learning state to a Forwarding state of a port in a bridge. The forward delay time contains two states, Listening state to Learning state and Learning state to Forwarding state. It assumes that the forward delay time is 15 seconds, then total forward delay time will be 30 seconds. This has much to do with the STP convergent time which will be more than 30 seconds because of other factors.
The valid value is 4 ~ 30 seconds, default is 15 seconds.

Force Version:

Two options are offered for choosing the STP algorithm. One is RSTP and the other is STP. If STP is chosen, RSTP will run as a legacy STP. The RC-2201 supports RSTP (802.1w) which is backward compatible with STP (802.1d).



Function name:

Port Setting

Function description:

In the STP Port Setting, users can disable and enable each port by selecting each Ports Status item. Users can also set "Path Cost" and "Priority" of each port by filling in the desired value and set the "Admin Edge Port" and the "Admin Point To Point" by selecting the desired item.

Parameter description:

Port Status:

It displays the current state of a port. We cannot manually set it because it displays the status only. There are three possible states. ( according to 802.1w specification)

• DISCARDING state indicates that this port can neither forward packets nor contribute learning knowledge.

Notice: Three other states (Disable state, BLOCKING state and LISTENING state) defined in the 802.1d specification are now all represented as DISCARDING state.

• LEARNING state indicates this port can now contribute its learning knowledge but cannot forward packets still.
• FORWARDING state indicates this port can both contribute its learning knowledge and forward packets normally.

Path Costs:

The contribution value of the path through this port to the Root Bridge. The STP algorithm determines a best path to Root Bridge by calculating the sum of path cost contributed by all ports on this path. A port with a smaller path cost value would become the Root Port. The range is 0 - 200,000,000. In the RC-2201, the path cost with 0 value means automatic which will automatically assign the path cost value defined by IEEE 802.1w. Default: 0

802.1w RSTP recommended value: (Valid range: 1 - 200,000,000)
10 Mbps: 2,000,000
100 Mbps: 200,000
1 Gbps: 20,000

Priority:

Priority here means Port Priority. Port Priority and Port Number are mixed to form the Port ID. Port IDs are often compared in order to determine which port of a bridge would become the Root Port. The range is 0 - 240. Default is 128. Admin Edge Port:

If user selects "Yes", this port will be an edge port. An Edge Port is a port connected to a device that knows nothing about STP or RSTP. Usually, the connected device is an end station. Edge Ports will immediately transit to forwarding state. User can select "Yes" or "No". Default: No

Admin Point To Point:

We say a port is on a point-to-point link if the port is in full-duplex mode. RSTP fast convergence can only happen on a point-to-point link. To determine if this port is on a point-to-point link is by auto-detecting the port's duplex mode if the parameter is set to "Auto". If the parameter is set to "True", the port is unconditionally considered to be on a point-to-point link. If the parameter is set to "False", fast transition to Forwarding state will not happen on this port. User can select "Auto", "True" or "False".
Default: Auto

M Check:
Migration Check. It forces the port sending out an RSTP BPDU instead of a legacy STP BPDU at the next transmission. The only benefit of this operation is to make the port quickly get back to act as an RSTP port. Click M Check button to send a RSTP BPDU from the port you specified.

3.3.7 Filtering Configuration

The filtering function in the RC-2201 is used to filter unwanted MAC addresses from accessing the converter based on some simple rules. The RC-2201 provides three types of filtering functions for security configuration. They are, Allow Forwarding MAC Address, Port Security Setting and Deny Forwarding MAC Address. You can configure it for different purposes. Here we list two examples for your reference.

Example 1:
Assumes an administrator wishes to specify a single station to access the converter from a specified port and the traffic from all other stations is rejected by that specified port.
How should we configure the RC-2201 to perform this operation?

Solution:
First, enter the function "Allowed Forwarding MAC Address" to add an entry with the MAC address of the specified station on the Allowed Forwarding table of the specified port. The Security Port of the specified port should be then enabled in the "Port Security Setting" function. After this process, the specified port will not allow any other station to access the converter except the specified station. And if this specified station is moved to another port, it will not be able to access the converter either.

Example 2:
Assumes an administrator wishes to deny a specified station from accessing the converter, which is to isolate the specified station from the converter. How should we configure the RC-2201 to accomplish this?

Solution:
To deny a specified station, it is easy. You just have to use the "Denied Forwarding MAC Address" function to configure it. Enter this function and press the Add button to add the MAC address of the specified station, which is to be rejected access to the converter.
The Deny Forwarding function is global. It is applied to the whole converter.

Function name:

Allowed Forwarding MAC Address

Function description:

Allowed Forwarding MAC Address is a function to allow the user in the Allowed Forwarding table to access a specified port of the converter. Allowed Forwarding table associated with a specified port of a converter is setup by manually inputting MAC addresses and its alias name. The data in the table is kept until the RC-2201 is powered off. The traffic with the source MAC address listed in the Allowed Forwarding Table can only access the converter from the port associated. The MAC address associated with the specified port cannot access any other port of the converter. All of the above settings will take effect only when "Port Security Setting" function of the associated port is enabled.

For adding a MAC address entry in the allowed table, you just need to fill in three parameters: MAC address, associated port, and priority. Just select the MAC address entry you want and click the Delete button, you also can remove it.

Parameter description:

Allowed Forwarding Table:

The table stores MAC address entries with associated port numbers and priorities, to provide the users listed in the table to access the associated port of the converter.

MAC Address:

It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens. For example,

00 - 00 - 8C - D6 - 00 - 01

TP1, Fx2:

The Port number of the RC-2201. It is 1 ~2. The TP port is number 1, Fibre port is number 2.

Priority:

This is for traffic priority. The user can configure a MAC address with a high priority or a low priority. If a MAC address is configured with a high priority, the packet with that DA or SA will be put into the high priority queue and be transmitted with high priority. If a MAC address is configured with a low priority, the packet with that MAC address will be transmitted with low priority.



Function name:

Port Security Setting

Function description:

The usage of Port Security has to combine with the Allowed Forwarding MAC Address function as mentioned above. In this function, you can enable it if you want to select the port. If the user ticks each port then, the ticked port will stop learning MAC Addresses and block any incoming packets except packets with the MAC Address listed in the Forwarding MAC Address table associated with that port. Click the Apply button for changes to take effect immediately.



Function name:

Denied Forwarding MAC Address

Function description:

Denied Forwarding MAC Address is a function that denies the packet forwarding if the packet's MAC Address is listed in the filtering MAC Address table. Users can very easily maintain the table by filling in the MAC Address field individually. Users also can insert or delete each entry by clicking the Add or Delete button.

Parameter description:

Denied Forwarding Table:

A table stored MAC address entry is used to provide the function to reject the users listed in this table to access the converter.

MAC Address:

It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens. For example,

00 - 00 - 8C - D6 - 00 - 01

3.3.8 VLAN Configuration

VLAN configuration is used to partition your LAN into small Virtual LAN's. If Properly configured, you can gain not only improvement with security and increased performance but it will also greatly reduce VLAN management. The RC-2201 supports Tag-based VLAN (802.1q) as well as protocol VLAN (802.1v). Tag-based VLAN (802.1q) also associates with GVRP for the management of dynamic tag-based VLAN. You can make VLAN configurations via the function VLAN Enable/Disable (VLAN State Setting) and VLAN Port VID Setting to configure VLAN parameters in the web user interface. Function name:

Function description:

In the Loopback Test function, there are two different loopback tests. One is an Internal Loopback Test and the other is an External Loopback Test. The former test function will not send the test signal outside the RC-2201 converter box. The test signal only wraps around in the RC-2201 converter box. As to the latter test function, it will send the test signal to its link partner. If you do not have them connected to active network devices, i.e. the ports do not have link, the RC-2201 will report the port numbers as failed. If they all are ok, it just shows OK.

Note: Whatever you choose Internal Loopback Test or External Loopback Test, these two functions will interfere with the normal system operation.



Function name:

Ping Test

Function description:

Ping Test function is a tool for detecting if the target device is alive or not through the ICMP protocol which abounds with report messages. The RC-2201 provides a Ping Test function to let you know if the target device is available or not. You can simply fill in a known IP address and then click the Ping Now button. After a few seconds, the RC-2201 will report whether the pinged device is alive or dead.

Parameter description:

After upgrading software, changing IP configuration or changing VLAN mode configuration, you must reboot to have the new configuration take effect. Here we are discussing the software reset function “reboot” in the main menu.

Function name:

Reboot

Function description:

Reboot the RC-2201. Reboot takes the same effect as the RESET button on the front panel of the RC-2201 converter. It will take around thirty (30) seconds to complete the system boot.

3.8 Logout

You can manually logout of the RC-2201 by performing the Logout function. You can also configure the RC-2201 to logout automatically.

Function name:

Logout

Function description:

The RC-2201 allows you to logout of the system to prevent other users from accessing the system without permission. If you do not logout and exit the browser, the RC-2201 will automatically logout for you.

Parameter description:

Auto Logout:

Select On/OFF. Default is ON. If it is “ON” and no action is performed or no key is pressed in any function screen for more than 3 minutes, the RC-2201 will logout automatically.

4. Operation of Menu-driven Console

1. The Managed Media Converter RC-2201 also provides a text-based menu- driven console by RS-232 terminal or Ethernet Port (telnet) to manage and monitor the port activity. Usually, in order to have the device connected to the management station, the console is used to change the settings such as IP address for the first time. For the detailed connection steps, please refer to the Section 2-2-2 in Chapter 2.
   
   Now, you can use the console to modify the IP setting through telnet program.
   
   The default values of the RC-2201 converter are as follows:
   IP Address: 192.168.1.1
   Subnet Mask: 255.255.255.0
   Default Gateway: 192.168.1.254
   Username: admin
   Password: admin
   
   
2. For instance, you can run a telnet session to 192.168.1.1, you will now be prompted for a username and password, enter the username and password as above.

4.1 Text-Based Menu-Driven Management Overview

After you have logged in to the converter the Main Menu will be displayed. On the menu, the user can use the arrow keys to navigate between each item and to press the Enter key to select the item you would like. The ESC key is used to return to the previous page.

The main functions of the converter will be listed in the middle of the console. The main functions of the converter are "Port Status & Counter", "System Information", "Configuration", "Diagnostics", "Show Log Data", "Software Upgrade", "Reboot" and "Logout".

Function name:

Port Configuration

Function description:

Changes the state and configuration of each port.

Parameter description:

Port:

The TP Port is the RC-2201's Ethernet UTP Interface. The Fibre Port is the RC-2201's Ethernet Fibre Interface.

State:

Shows if the communication capabilities of the port is Enabled or Disabled. When Enabled, traffic can be transmitted and received via this port. When Disabled, the port is blocked and no traffic can be transferred through this port. The Port State is configured by the user. There are only two states available Enable and Disable. If the ports state is set to Disabled, then that port is prohibited from passing any traffic, even if it has link. The default value is Enabled.

Auto Negotiation:

Two states can be chosen, Enable and Disable. Enable means the port will use the auto-negotiation algorithm to exchange the speed, duplex and flow control settings with the linked partner. When enabled, the speed, duplex mode and flow control settings may change. Disable means that forced mode will be used. When disabled, if you want to set up a connection successfully, the port configuration should be the same for the local port and the linked partner. If their configuration is different, link between the two devices may not be established. The RC-2201, fibre port supports forced mode only.

Speed/Duplex:

Is used to set the speed and duplex settings. The copper port can either run at 10Mbps, 100Mbps or 1000Mbps and can run at half or full duplex. The fibre port can only run at 1000Mbps and can also run at half or full duplex.

Flow Control:

There are two modes that can be chosen, Enable and Disable. If flow control is set to Enable, both parties can send PAUSE frames to the transmitting device if the receiving port is to busy to handle the requests. When set to Disable, flow control will not exist on that port and if the port is to busy to handle the request the packet will be dropped. Default: Enable

4.3.1 System Configuration

There are seven functions contained in the System Configuration function folder. They are Create Username/Password, Change Username/Password, IP Configuration, System Time Setting, Location/Contact Setting, TP Port Management and Power Down Setting.

4.3.1.1 Create Username / Password

In this function, only the administrator can create a new guest username and password. Only one administrator account and a maximum of four guest accounts are allowed to exist in the RC-2201.
The default setting is as follows:
Username: admin
Password: admin

4.3.1.2 Change Username / Password

In this function, only the administrator can create, modify or delete the username and password. Administrators can modify other guest identities' passwords without confirming the password but it is necessary to modify the administrator-equivalent identity. Guest-equivalent identities can only modify his own password. Please note that you must confirm administrator/guest identity on the list of Username in advance before configuring the username and password.
The default setting is as follows:
Username: admin
Password: admin

4.3.1.3 IP Configuration

The IP configuration is one of the most important configurations in the RC-2201. Without the correct settings the network manager will not be able to see the device. The RC-2201 supports both manual IP address setting and automatic IP address setting via a DHCP Server. When the IP address is changed you must reboot the converter for the setting to take effect.

Function name:

IP Configuration

Function description:

Set IP address, subnet mask, default gateway and DNS for the RC-2201.

Parameter description:

DHCP:

The RC-2201 supports DHCP client mode, which allows the converter to obtain an IP address automatically if this function is set to Enable. The RC-2201 will find the DHCP server on the network and request an IP address. If there is no DHCP server available on the network the RC-2201 will count down from 60 seconds, if the DHCP server still does not respond the RC-2201 will use it's last pre-configured IP address. If this function is set to Disable, you will have to set an IP address manually. Default: Disable

IP Address:

If the DHCP function is set to Disable the user can configure the IP settings for the converter. Default: 192.168.1.1

Subnet Mask:

Set the subnet mask to a value corresponding to your current network settings. Default: 255.255.255.0

Default Gateway:

Set an IP address for a gateway to handle those packets that do not meet the rules predefined in a device. If a packet does not meet the criteria for other routers, then it must be sent to a default router. This means any packet with undefined TCP/IP information will be sent to this device unconditionally. Default: 192.168.1.254

DNS:

Set an IP address for a Domain Name Server. The RC-2201 DNS client program will ask the Domain Name Server to resolve the IP address of the named host. To select the "Manual" for fixed DNS IP address setting. To select "Auto" the DNS IP address will be assigned from DHCP server. The default DNS setting is empty. Default: DNS : 0.0.0.0

4.3.1.4 System Time Setting

The RC-2201 provides manual and automatic ways to set the system time via NTP. Manual setting is simple, you just input the "Year", "Month", "Day", "Hour", "Minute" and "Second" within the valid value range indicated in each item. If you input an invalid value, for example, 61 in minute, the converter will change the value to 59.

NTP is a well known protocol used to synchronise the clock of the RC-2201 system time over a network. NTP, an internet draft standard formalised in RFC 1305, has been adopted on the system version 3 protocol. The RC-2201 provides four built-in real internet site NTP server IP addresses and a user-defined NTP server IP address. The time zone is Greenwich-centered which uses the expression form of GMT +/- xx hours.

Function name:

System Time Setting

Function description:

Set the system time manually or get the network time from a NTP server for system time reference in the RC-2201.

Parameter description:

Manual:

The user can key in the Year, Month, Day, Hour, Minute and Second directly to synchronise the system time with the local time. Default: Year=2000, Month=1, Day=1, Hour=0, Minute=0 Second=0

NTP:

Select the NTP protocol to synchronise the system time, you will only need to choose a NTP server and select a Time Zone. Then, click the Apply button, the system will take effect immediately. This will not automatically update the system time periodically.

4.3.1.5 Location/Contact Setting

Function name:

Location/Contact Setting

Function description:

The Location and Contact fields can be filled in with some useful information for the network managers reference. The location field can contain the devices location information. Thus, the device maintainer can easily find the device. The contact field can contain the devices maintainer information e.g. name, phone number, etc..

Parameter description:

Location:

The location field can contain the devices location information with any visual characters. The default setting is empty. User-defined.

Contact:

The contact field can contain the devices maintainer information with any visual characters. The default setting is empty. User-defined.

4.3.1.6 TP Port Management

Function name:

TP Port Management

Function description:

The TP Port Management function is used to disable the use of management through the TP Port. When disabled Administrators will no longer be able to manage the device through the TP Port.

Parameter description:

Disable:

To isolate traffic from the managed RC-2201 requests from TP port when the TP port management is set to "Disabled".

Enable:

Allows traffic to pass with the managed RC-2201 request from the TP port when the TP port management is set to "Enabled". Default: Enable

4.3.1.7 Power Down Setting

Function name:

Power Down Setting

Function description:

This function is designed for safety reasons. It will detect two things: If the temperature is over 60 oC or if the cooling fan has failed. If these two conditions happen at the same time and the "Power Down Setting" is enabled, the RC-2201 will power down automatically.

Parameter description:

Disable:

The RC-2201 will not power down automatically, while the temperature is over 60 oC and the cooling fan has failed. If the two conditions happen at the same time and the "Power Down Setting" is disabled.

Enable:

The RC-2201 will power down automatically, while the temperature is over 60 oC and the cooling fan has failed. If the two conditions happen at the same time and the "Power Down Setting" is enabled.

4.3.2 SNMP Configuration

Function name:

SNMP Configuration

Function description:

Any network management station running the Simple Network Management Protocol (SNMP) can manage the converter which is equipped with an SNMP Agent, provided that the Management Information Base (MIB) is installed correctly on the management station. SNMP is a protocol that is used to govern the transfer of information between a SNMP Manager and Agent. The SNMP agent will only run on the converter if you have enabled SNMP. If disabled the related community name, trap host IP address, trap and RMON counters will be ignored.

In the SNMP Configuration function, the community string is used as a password to authenticate the request. If both devices have the same community name, then they can talk to each other; otherwise, the network management unit cannot access the converter via the SNMP protocol. To set up a trap host means to create a trap manager by assigning an IP address to receive the trap message. In other words, the trap host is a network management unit with a SNMP manager which receives the trap messages from the converter. You can configure up to 4 trap hosts to prevent important trap messages from being lost.

A SNMP manager must pass the authentication so that it can access the agent. So, both parties must have the same community name. You can also define the system name, system location and contact person for easy management via the SNMP manager. Fill in the data, then click the Apply button to apply the new settings.



Three functions are offered in the SNMP configuration, including SNMP Status, Community Strings and Trap Configuration. The explanations of these functions are as below in order.

Function name:

SNMP Status

Parameter description:

SNMP Status:

SNMP enable/disable selection. Default is Enable.

Function name:

Community Strings

Parameter description:

Get Community Name:

User-definable community name for the authentication of the SNMP Get Community, the default is public.

Set Community Name:

User-definable community name for the authentication of SNMP Set Community, the default is private.

Trap Host 1-4 IP Address / Community Name:

Users can fill in specified trap host 1-4 IP addresses with SNMP community name.

Function name:

Trap Configuration

Function description:

Trap is a PDU packet sent by the SNMP agent in the Managed Media Converter. The Managed Media Converter will send the trap packet containing the useful information about an unusual event to the SNMP manager. The information includes cold start trap, warm start trap, link down trap, link up trap and authentication failure trap. In the RC-2201 Converter, the SNMP agent will automatically send cold start trap and warm start trap to SNMP manager after booting successfully.

Parameter description:

Cold Start Trap:

This trap packet will be sent while the RC-2201 Converter’s power is cycling.

Warm Start Trap:

This trap packet will be sent while rebooting the RC-2201 Converter by means of pressing the RC-2201’s RESET button or running Reboot function of software.

Link Down Trap:

This trap packet will be sent while the RC-2201 Converter’s UTP link status has changed from up to down. The Link Down Trap Packet will not be sent while the RC-2201 Converter’s fibre port link status has changed from up to down. The fibre port Link Down Event will be stored in the Log Data.

Link Up Trap:

This trap packet will be sent while the RC-2201 Converter’s UTP or Fibre port link status has changed from down to up.

Authentication Failure Trap:

This trap packet will be sent while the RC-2201 SNMP agent authentication failure occurs. Authentication failure means that the SNMP agent receives a SNMP request with an incorrect community name.

4.3.3 Packet Length Setting

The RC-2201 provides two levels of Ethernet frame size for the user to configure. One is 1536 bytes and the other is 1522 bytes. After selecting one of these two options and then pressing the Apply button, the setting will take effect immediately. Default setting is 1522 bytes long which will accommodate the size of the tagged VLAN frame.

4.3.4 Broadcasting Suppression

Function name:

Broadcasting Suppression

Function description:

The Broadcasting Suppression function is used to spread the request of broadcast packets into a larger time frame to prevent traffic congestion due to broadcast packets from multiple network devices trying to connect to NMS, boot servers or DHCP servers.

The RC-2201 supports a random delay time for DHCP and boot delay for each device. This suppresses the broadcast storm when all devices are at booting stage at the same time. The maximum user-defined delay time is 30 sec. If the Broadcasting Suppression function is enabled, the delay time is set randomly, ranging from 0 to 30 seconds, because the exact delay time is computed by the converter itself. The default is “Disable”.

4.3.5 Spanning Tree Configuration

The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, ensure that only one path is active between any two nodes on the network at a time. User can enable Spanning Tree Protocol on converter's web management and then set up other advanced items. We recommend that you enable STP on all converters to ensure a single active path on the network.

4.3.5.1 STP Enable/Disable

Function name:

STP Enable/Disable

Function description:

Spanning Tree Protocol: User can use the Space key to toggle the status of this function.



Parameter description:

Spanning Tree Protocol:

Set 802.1W Rapid STP function Enable / Disable. Default is "Disable"

4.3.5.2 STP Status

Function name:

STP Status

Function description:

In the Spanning Tree Status, the user can read 11 parameters about the STP current status. The 11 parameters are described in the list below:



Parameter description:

Bridge ID:

Shows the converter's bridge ID which stands for the MAC address of this converter.

Bridge Priority:

Shows the converter's current bridge priority setting. Default is 32768.

Designated Root:

Shows the root bridge ID of this network segment. If this converter is a root bridge, the "Designated Root" will show this converter's bridge ID.

Designated Priority:

Shows the current root bridge priority.

Root Port:

Shows the port number connected to the root bridge with the lowest path cost.

Root Path Cost:

Shows the path cost between the root port and the designated port of the root bridge.

Current Max. Age:

Shows the current root bridge maximum age time. Maximum age time is used to monitor if STP topology needs to change. When a bridge does not receive a hello message from root bridge until the maximum age time is counted down to 0, the bridge will treat the root bridge as malfunctioned and issue a Topology Change Notification (TCN) BPDU to all other bridges. All bridges in the LAN will re-learn and determine which the root bridge is. Maximum Age time is assigned by the root bridge in units of seconds. Default is 20 seconds.

Current Forward Delay:

Shows the current root bridge forward delay time. The value of the Forward Delay time is set by the root. The Forward Delay time is defined as the time spent changing from a Listening state to a Learning state or from a Learning state to a Forwarding state of a port in a bridge.

Hello Time:

Shows the current hello time of the root bridge. The Hello time is a time interval specified by the root bridge, used to request all other bridges periodically sending a hello message every "hello time" second to the bridge attached to its designated port.

Topology Change Count:

STP Topology Change Count expresses the time spent in units of seconds since the beginning of the Spanning Tree Topology Change to the end of the STP convergence. Once the STP change is converged, the Topology Change count will be reset to 0. The figures showing in the screen may not be the exact time it spent but very close to, because the time is eclipsing.

Time Since Last Topology Change:

Time Since Last Topology Change is the accumulated time in units of seconds the STP has been since the last STP Topology Change was made. When a Topology Change is initiated again, the counter will be reset to 0. And it will also count again once STP topology Change is completed.

4.3.5.3 STP Configuration

The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning Tree Configuration, there are six parameters open for the user to configure. Each parameter description is listed below.

Function name:

STP State Setting

Function description:

The user can set the following Spanning Tree parameters to control the STP function enable/disable, select which mode RSTP/STP and allow the STP state machine behavior to send BPDU in this converter. The default setting of Spanning Tree Protocol is "Disable".

Parameter description:

Spanning Tree Protocol:

Set 802.1W Rapid STP function Enable / Disable. Default is "Disable"

Bridge Priority:

The lower the bridge priority is, the higher priority it has. Usually, the bridge with the highest bridge priority is the root. If you want to have the RC-2201 as the root bridge, you can set this value lower than that of a bridge in the LAN. The valid value is 0 ~ 61440. The default is 32768.

Hello Time:

Hello Time is used to determine the periodic time to send normal BPDU from designated ports among bridges. It decides how long a bridge should send this message to other bridges to tell them I am alive. When the RC-2201 is the root bridge of a LAN, for example, all other bridges will use the hello time assigned by the RC-2201 to communicate with each other. The valid value is 1 ~ 10 in units of seconds.
Default is 2 seconds.

Max. Age:

When the RC-2201 is the root bridge, the whole LAN will apply this figure set by the RC-2201 as their maximum age time. When a bridge receives a BPDU originated from the root bridge and if the message age conveyed in the BPDU exceeds the Max. Age of the root bridge, the bridge will treat the root bridge as malfunctioned and issue a Topology Change Notification (TCN) BPDU to all other bridges. All bridges in the LAN will re-calculate and determine who the root bridge is. The valid value of Max. Age is 6 ~ 40 seconds.
Default is 20 seconds.

Forward Delay:

You can set the root bridge forward delay time. This figure is set by the root bridge only. The forward delay time is defined as the time spent changing from a Listening state to a Learning state and also from a Learning state to a Forwarding state of a port in a bridge. The forward delay time contains two states, Listening state to Learning state and Learning state to Forwarding state. It assumes that the forward delay time is 15 seconds, then total forward delay time will be 30 seconds. This has much to do with the STP convergent time which will be more than 30 seconds because of other factors.
The valid value is 4 ~ 30 seconds, default is 15 seconds.

Force Version:

Two options are offered for choosing the STP algorithm. One is RSTP and the other is STP. If STP is chosen, RSTP will run as a legacy STP. The RC-2201 supports RSTP (802.1w) which is backward compatible with STP (802.1d).



Function name:

Port Setting

Function description:

In the STP Port Setting, users can disable and enable each port by selecting each Ports Status item. Users can also set "Path Cost" and "Priority" of each port by filling in the desired value and set the "Admin Edge Port" and the "Admin Point To Point" by selecting the desired item.

Parameter description:

Port Status:

It displays the current state of a port. We cannot manually set it because it displays the status only. There are three possible states. ( according to 802.1w specification)

• DISCARDING state indicates that this port can neither forward packets nor contribute learning knowledge.

Notice: Three other states (Disable state, BLOCKING state and LISTENING state) defined in the 802.1d specification are now all represented as DISCARDING state.

• LEARNING state indicates this port can now contribute its learning knowledge but cannot forward packets still.
• FORWARDING state indicates this port can both contribute its learning knowledge and forward packets normally.

Path Costs:

The contribution value of the path through this port to the Root Bridge. The STP algorithm determines a best path to Root Bridge by calculating the sum of path cost contributed by all ports on this path. A port with a smaller path cost value would become the Root Port. The range is 0 - 200,000,000. In the RC-2201, the path cost with 0 value means automatic which will automatically assign the path cost value defined by IEEE 802.1w. Default: 0

802.1w RSTP recommended value: (Valid range: 1 - 200,000,000)
10 Mbps: 2,000,000
100 Mbps: 200,000
1 Gbps: 20,000

Priority:

Priority here means Port Priority. Port Priority and Port Number are mixed to form the Port ID. Port IDs are often compared in order to determine which port of a bridge would become the Root Port. The range is 0 - 240. Default is 128. Admin Edge Port:

If user selects "Yes", this port will be an edge port. An Edge Port is a port connected to a device that knows nothing about STP or RSTP. Usually, the connected device is an end station. Edge Ports will immediately transit to forwarding state. User can select "Yes" or "No". Default: No

Admin Point To Point:

We say a port is on a point-to-point link if the port is in full-duplex mode. RSTP fast convergence can only happen on a point-to-point link. To determine if this port is on a point-to-point link is by auto-detecting the port's duplex mode if the parameter is set to "Auto". If the parameter is set to "True", the port is unconditionally considered to be on a point-to-point link. If the parameter is set to "False", fast transition to Forwarding state will not happen on this port. User can select "Auto", "True" or "False".
Default: Auto

M Check:
Migration Check. It forces the port sending out an RSTP BPDU instead of a legacy STP BPDU at the next transmission. The only benefit of this operation is to make the port quickly get back to act as an RSTP port. Click M Check button to send a RSTP BPDU from the port you specified.

4.3.6 Misc. Feature Configuration

The Miscellaneous Feature Configuration gathers many functions, including MAC Address Aging Time Setting, Broadcast Storm Filter Limit, Priority Queue Service, Max. bridge transmit delay bound control and QoS Policy. They are described below.

Function name:

MAC Table Maintenance

Function description:

This function is used to set the MAC Address Age-out Time applied to the whole MAC address table except some static MAC addresses. The range of MAC table entry age-out time is from 30, 33, 36,…765 seconds.
If a source node has not visited the converter for a time longer than the Age-out Time, its responded MAC address information in the converter's MAC table will be marked invalid by the converter's aging function. This age-out rule will not be applied to the static MAC addresses.
The default age-out time is 300 seconds.



Function name:

Broadcast Storm Filtering

Function description:

The Broadcast Storm Filtering is applied to filter the converter's broadcast traffic. If you choose an upper threshold, it is enabled. It is a global function. The setting will be applied to all ports of the converter. The threshold is the percentage of the port's total bandwidth used by broadcast traffic. When broadcast traffic for a port rises above the threshold you set, broadcast storm filter discards the extra broadcast traffic. This keeps the total broadcast traffic less than the threshold able to be forwarded and limits too many broadcast packets running over the network. The RC-2201 supports five threshold values, including 5%, 10%, 15%, 20%, and 25%.
Default is OFF.



Function name:

Priority Queue Service

Function description:

The RC-2201 provides three priority queue services for transmission scheduling, including FCFS, strict priority and WRR. It is a global function.
First Come First Service (FCFS): All incoming packets will be sent out upon the sequence of packet's arrival order.

All High before Low: After all high priority packets are sent out, then low ones are sent in turn.

Weighted Round Robin (WRR): This is actually a transmission ratio of high priority packets and low priority packets. If you would like to repeatedly send 5 high priority packets first and then 2 low priority packets. You can set a 5 to high weight field and a 2 to low weight field in WRR function row.
The WRR Default Setting High = 2, Low = 1

Parameter description:

Max. bridge transmit delay bound control

The function "Maximum bridge transmit delay bound control" is applied to limit the maximum queuing time of the packets in the converter. If enabled, the packets queued over the time set will be dropped. Valid values are 1 sec., 2 sec., 4 sec. and OFF.
Default value is OFF.

Delay Bound:

Limit the resided time of the low priority packets in the converter. If the low priority packet is not transmitted out and time set by "Delay bound" is enabled, the packet will be dropped. The valid delay time is 1 - 255 ms and OFF.
Default Max. Delay Time is 1ms.

Note:
Make sure that "Max. bridge transmit delay bound control" is enabled before enabling Delay Bound, because Enable Delay Bound will only work when "Max. bridge transmit delay bound control is enabled".



Function name:

QoS Policy

Function description:

It is used to assign which priority level is high or low. Normally, we map the priority levels 7 - 4 to be high priority and the priority levels 3 - 0 to be low priority. The mapped priority will be applied to the forwarding scheduler. In the RC-2201, it is FCFS, Strict and WRR. The QoS policy is global.
Default: If enabled, priority levels 7 - 4 are assigned to be high priority, and priority levels 3 - 0 are assigned to be low priority.

4.3.7 Filtering Configuration

The filtering function in the RC-2201 is used to filter unwanted MAC addresses from accessing the converter based on some simple rules. The RC-2201 provides three types of filtering functions for security configuration. They are, Allow Forwarding MAC Address, Port Security Setting and Deny Forwarding MAC Address. You can configure it for different purposes. Here we list two examples for your reference.

Example 1:
Assumes an administrator wishes to specify a single station to access the converter from a specified port and the traffic from all other stations is rejected by that specified port.
How should we configure the RC-2201 to perform this operation?

Solution:
First, enter the function "Allowed Forwarding MAC Address" to add an entry with the MAC address of the specified station on the Allowed Forwarding table of the specified port. The Security Port of the specified port should be then enabled in the "Port Security Setting" function. After this process, the specified port will not allow any other station to access the converter except the specified station. And if this specified station is moved to another port, it will not be able to access the converter either.

Example 2:
Assumes an administrator wishes to deny a specified station from accessing the converter, which is to isolate the specified station from the converter. How should we configure the RC-2201 to accomplish this?

Solution:
To deny a specified station, it is easy. You just have to use the "Denied Forwarding MAC Address" function to configure it. Enter this function and press the Add button to add the MAC address of the specified station, which is to be rejected access to the converter.
The Deny Forwarding function is global. It is applied to the whole converter.

Function name:

Allow Forwarding MAC Address

Function description:

Allow Forwarding MAC Address is a function to allow the user in the Allowed Forwarding table to access a specified port of the converter. Allowed Forwarding table associated with a specified port of a converter is setup by manually inputting MAC addresses and its alias name. The data in the table is kept until the RC-2201 is powered off. The traffic with the source MAC address listed in the Allowed Forwarding Table can only access the converter from the port associated. The MAC address associated with the specified port cannot access any other port of the converter. All of the above settings will take effect only when "Port Security Setting" function of the associated port is enabled.

For adding a MAC address entry in the allowed table, you just need to fill in three parameters: MAC address, associated port, and priority. Just select the MAC address entry you want and click the Delete button, you also can remove it.



Parameter description:

Create New Entry:

Add an allowed forwarding MAC address entry. It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens. For example,

00 - 00 - 8C - D6 - 00 - 01

TP1, Fx2:

The Port number of the RC-2201. It is 1 ~2. The TP port is number 1, Fibre port is number 2.

Priority:

This is for traffic priority. The user can configure a MAC address with a high priority or a low priority. If a MAC address is configured with a high priority, the packet with that DA or SA will be put into the high priority queue and be transmitted with high priority. If a MAC address is configured with a low priority, the packet with that MAC address will be transmitted with low priority.



Delete Entry:

Delete an entry from the allowed forwarding MAC address table.

Function name:

Port Security

Function description:

The usage of Port Security has to combine with the Allowed Forwarding MAC Address function as mentioned above. In this function, you can enable it if you want to select the port. If the user ticks each port then, the ticked port will stop learning MAC Addresses and block any incoming packets except packets with the MAC Address listed in the Forwarding MAC Address table associated with that port. Click the Apply button for changes to take effect immediately.



Function name:

Denied Forwarding MAC Address

Function description:

Denied Forwarding MAC Address is a function that denies the packet forwarding if the packet's MAC Address is listed in the filtering MAC Address table. Users can very easily maintain the table by filling in the MAC Address field individually. Users also can insert or delete each entry by clicking the Add or Delete button.



Parameter description:

Create New Entry:

Add a denied forwarding MAC address entry.

MAC Address:

It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens. For example,

00 - 00 - 8C - D6 - 00 - 01



Delete Entry:

Delete an entry from the denied forwarding MAC address table.

4.3.8 VLAN Configuration
