Copper Distributed Data Interface (CDDI) is the implementation of Fiber Distributed Data Interface (FDDI) protocols over shielded twisted-pair and unshielded twisted-pair (UTP) cabling. CDDI transmits over relatively short distances (about 100 meters), providing data rates of 100 Mbps, using a dual-ring architecture to provide redundancy. FDDI is a LAN standard, defined by ANSI X3T9.5, specifying a 100-Mbps token-passing network using fiber-optic cable, with transmission distances of up to 2 kilometers (km). FDDI also uses a dual-ring architecture to provide redundancy.
This chapter describes how to use the console port to configure the CDDI/FDDI ports of the
Catalyst 5000 series switch. For definitions of all commands discussed in this chapter, refer to the
Catalyst 5000 Series Command Reference publication.
The features you can customize have default values that will most likely suit your environment and probably need not be changed. The default values of these features are set as follows:
To customize the preceding features to fit your particular configuration, perform the appropriate tasks in the following sections.
When you insert or replace FDDI modules, clear the module configuration information using the command clear config mod_num to obtain the correct spanning-tree parameters for the modules.
The Catalyst 5000 series switch can forward Internet Packet Exchange (IPX) packets received on FDDI ports to Ethernet ports, or it can forward IPX packets received on Ethernet ports to FDDI ports. To do this, the switch must be configured for specific IPX protocol translations. By default, these IPX protocol translations are configured:
You can customize these settings if your environment requires it.
The FDDI SNAP frame can be translated into these Ethernet frames:
To specify the FDDI protocol to which Ethernet 8023RAW packets are translated, perform these steps in privileged mode:
| Task | Command |
|---|---|
| Step 1 Configure the appropriate translation protocol. | set bridge ipx snaptoether {8023 | SNAP | EII | 8023RAW} |
| Step 2 Verify that the correct translation protocol was configured. | show bridge |
After entering the set bridge ipx snaptoether 8023 command, you see this display:

The FDDI 802.2 frame can be translated into these Ethernet frames:
To specify the Ethernet frame to which IPX FDDI SNAP packets are translated, perform these steps in privileged mode:
| Task | Command |
|---|---|
| Step 1 Configure the appropriate protocol translation. | set bridge ipx 8022toether {8023 | SNAP | EII | 8023RAW} |
| Step 2 Verify that the correct protocol translation was configured. | show bridge |
After setting the IPX translation protocol for FDDI 802.2 to 802.3, you see this display:

The TL_MIN parameter sets the minimum time to transmit an FDDI physical sublayer (PHY) line state before advancing to the next physical connection management (PCM) state. This setting affects the station and switch interoperability and might hinder the implementation of FDDI repeaters. By default, the TL_MIN parameter is set to 40 microseconds. Normally, you will not need to adjust this parameter. However, you can customize the TL_MIN setting if needed.
To set the minimum time to transmit an FDDI PHY line state, perform this task in privileged mode:
| Task | Command |
|---|---|
| Set TL_MIN to a value between 40 and 1,340,006 microseconds. | set fddi tlmin mod_num/port_num microseconds |
After entering the fddi tlmin command, you see this display:
Console> (enable) set fddi tlmin 4/1 40 Port 4/1 tlmin set to 40. Console> (enable)
To verify that you have correctly configured TL_MIN, enter the show fddi command. After entering this command, you see this display:
Console> show fddi Mod SMT User-Data T-Notify TReq --- -------------------------- -------- ------- 4 Engineering 15 3500 5 abc 20 150000 Port Tlmin Ler-CutOff Ler-Alarm ----- -------- ---------- --------- 4/1 40 10 11 4/2 40 10 11 5/1 40 10 11 5/2 40 9 12 Console>
The TNotify parameter sets the interval (in seconds) between neighbor notification frames. These frames are sent out to notify neighboring devices of FDDI module Media Access Control (MAC) addresses. Usually, the default setting of 30 seconds is sufficient. By shortening the interval, you cause more notification frames to be sent.
If you need to adjust the interval between neighbor notification frames, perform this task in privileged mode:
| Task | Command |
|---|---|
| Set TNotify to a value between 2 and 30 seconds. | set fddi tnotify mod_num time |
After entering the set fddi tnotify command, you see this display:
Console> (enable) set fddi tnotify 4/1 15 Module 4 tnotify set to 15. Console> (enable)
To verify that you correctly configured TNotify, enter the show fddi command. After entering the command, you see this display:

The TRequest parameter specifies the FDDI switch's required value for the Token Ring Timer (TRT). This value is used to negotiate the TRT with other stations. The TRT is used to control ring scheduling during normal operation and to detect and recover from serious ring error situations. Whenever the TRT value expires, the station uses the TRequest value to negotiate with other stations for the lowest value. The default setting of 165,000 microseconds is sufficient for most networks.
If you need to modify the setting for the TRequest parameter, perform this task in privileged mode:
| Task | Command |
|---|---|
| Set TRequest to a value between 2502 and 165,000 microseconds. | set fddi trequest mod_num time |
After entering the set fddi trequest command, you see this display:
Console> (enable) set fddi trequest 4 3500 Mac 4/1 treq set to 3500. Console> (enable)
To verify that you correctly configured TNotify, enter the show fddi command. After entering the command, you see this display:

The user-data string identifies the user data string in the Station Management (SMT) Management Information Base (MIB) of an FDDI module. The default value is Catalyst 5000. This value should be modified to a more meaningful description.
To modify the user-data string, perform this task in privileged mode:
| Task | Command |
|---|---|
| Enter a module number and a unique description or name to identify the FDDI module. | set fddi userdata mod_num userdata_string |
After entering the set fddi userdata command, you see this display:
Console> (enable) set fddi userdata 4 Engineering Module 4 userdata set to Engineering. Console> (enable)
To verify that you entered the description or name correctly, enter the show fddi command. After entering the command, you see this display:

IP fragmentation allows the Catalyst 5000 series switch to fragment large FDDI IP frames (frames greater than 1514 bytes) into multiple smaller packets so that they can be transmitted on an Ethernet segment.
The procedures in this section describe disabling and reenabling IP fragmentation. By default, IP fragmentation is enabled.
If you want the large packets to be dropped instead of fragmented, disable fragmentation by entering this command:
| Task | Command |
|---|---|
| Disable IP fragmentation. | set ip fragmentation disable |
After entering the set ip fragmentation disable command, you see this display:
Console> (enable) set ip fragmentation disable IP fragmentation disabled for module 4 Console> (enable)
To reenable IP fragmentation, perform this task in privileged mode:
| Task | Command |
|---|---|
| Enable IP fragmentation. | set ip fragmentation enable |
After disabling or reenabling IP fragmentation, verify that you correctly set IP fragmentation by entering the show ip route command. After entering the command, you see this display:
Console> (enable) show ip route Fragmentation Redirect Unreachable ------------- -------- ----------- disabled enabled disabled Destination Gateway Flags Use Interface --------------- --------------- ------ ---------- --------- 172.20.0.0 172.20.22.181 U 0 sc0 default default UH 0 sl0 Console> (enable)
When the Internetworking Control Message Protocol (ICMP) Unreachable Messages feature is enabled, the switch returns an ICMP unreachable message to the Internet source host whenever it receives an IP datagram that it cannot deliver. When the ICMP Unreachable Messages feature is disabled, the switch does not notify the Internet source host when it receives an IP datagram that it cannot deliver. If desired, you can disable the ICMP unreachable messages feature.
This section describes how to disable and reenable IP unreachable messages.
To disable unreachable messages, perform this task in privileged mode:
| Task | Command |
|---|---|
| Disable IP unreachable messages. | set ip unreachable disable |
To reenable IP unreachable messages, perform this task in privileged mode:
| Task | Command |
|---|---|
| Enable IP unreachable messages. | set ip unreachable enable |
To verify that IP unreachable messages are enabled or disabled, enter the show ip route command.
The link error rate (LER)-alarm value defines the LER at which a link connection exceeds a preset alarm threshold. This value is used in the LER threshold test. The default setting of 8 (10¯8) link errors per second is sufficient for most networks.
To modify the setting for the LER alarm, perform this task in privileged mode:
| Task | Command |
|---|---|
| Change the LER-alarm setting. | set fddi alarm mod_num/port_num value |
After entering the set fddi alarm command, you see this display:
Console> (enable) set fddi alarm 4/1 11 Port 4/1 alarm value set to 11. Console> (enable)
To verify that you have correctly set the LER alarm value, enter the show fddi command. After entering this command, you see this display:
Console> show fddi Mod SMT User-Data T-Notify TReq --- -------------------------- -------- ------- 4 Engineering 15 3500 5 abc 20 150000 Port Tlmin Ler-CutOff Ler-Alarm ----- -------- ---------- --------- 4/1 40 10 11 4/2 40 10 11 5/1 40 10 11 5/2 40 9 12 Console>
The LER-cutoff value determines the LER at which a connection is flagged as faulty. This value is used in the LER threshold test. The default setting of 7 (10¯7) is sufficient for most networks.
To modify the LER cutoff setting, perform this task in privileged mode:
| Task | Command |
|---|---|
| Change the LER-Cutoff setting. | set fddi cutoff mod_num/port_num value |
After entering the set fddi cutoff command, you see this display:
Console> (enable) set fddi cutoff 4/1 10 Port 4/1 cutoff value set to 10. Console> (enable)
To verify that the LER-Alarm setting is correct, enter the show fddi command. After entering this command, you see this display:

To assign an Ethernet virtual local-area network VLAN to map to the native VLAN on an FDDI port, perform the following task. The native VLAN must be of Ethernet type. The FDDI module translates all native (non-802.10) FDDI traffic to the assigned Ethernet VLAN.
To set up a native VLAN on FDDI, perform this task:
| Task | Command |
|---|---|
| Assign a VLAN to map to native traffic on an FDDI port. | set vlan vlan_num mod_num/port_num |
The VLAN designated in the set vlan command must be an Ethernet type VLAN. After entering the set vlan command, you see this display:

This section describes how to set up an FDDI 802.10 VLAN configuration.
These recommendations apply to setting up an FDDI 802.10 configuration:
Before setting up an FDDI 802.10 configuration, read these sections:
After completing the prerequisites, perform these tasks in privileged mode to set up the 802.10 VLAN configuration.
| Task | Command |
|---|---|
| Step 1 Provide a VLAN number and activate a VLAN in the management domain. | set vlan vlan_num |
| Step 2 Create a VLAN with the type FDDI. | set vlan vlan_num type fddi |
| Step 3 Map the Ethernet VLAN translation to an FDDI VLAN. | set vlan ether_vlan_num translation fddi_vlan_num OR
set vlan fddi_vlan_num translation ether_vlan_num |
| Step 4 Turn the trunking on for the FDDI port. | set trunk mod_num/port_num on |
Performing the task in Step 1 creates a VLAN but does not assign it to a port. VLAN Trunk Protocol (VTP) advertises the VLAN to available trunks of all types, such as Ethernet and FDDI, that are set to on for all Catalyst 5000 series switches in the same management domain.
To verify that the VLAN configuration and mapping between Ethernet, FDDI, and Token Ring is correct, enter the show vlan {trunk | no trunk} command and the show trunk command. If you use the show trunk command after a 30-second delay, you will see a display of the new VLAN that has been added to all Catalyst 5000 series switches. Refer to the FDDI 802.10 configuration example for a display of the show vlan command.
This example shows two Catalyst 5000 series switches in an FDDI 802.10 VLAN configuration.
After completing the tasks in Chapter 7, "Configuring Virtual LANs," perform these steps in privileged mode to set up the FDDI 802.10 VLAN configuration:
Step 1 Provide a VLAN number and activate the VLAN in the management domain by entering the set vlan vlan_num command. You see this display:
Console> (enable) set vlan 33
VTP: vlan addition successful
This creates a VLAN but does not assign it to a port. VTP advertises the VLAN to all available trunks of all types (such as Ethernet or FDDI) that are set to on, for all Catalyst 5000 series switches in the same management domain.
Step 2 Create a VLAN with type FDDI by entering the set vlan vlan_num type fddi command. You see this display:
Console> (enable) set vlan 333 type fddi (said 338)
VTP: vlan addition successful
Step 3 Map the Ethernet VLAN translation to an FDDI VLAN by entering the set vlan ether_vlan_num translation fddi_vlan_num command or the set vlan fddi_vlan_num translation ether_vlan_num command. You see this display:
Console> (enable) set vlan 33 translation 333
VTP: vlan modification successful
Step 4 Turn trunking on for the FDDI port by entering the set trunk mod_num/port_num on command. You see this display:
Console> (enable) set trunk 1/1 on
Port 1/1 mode set to on.
Console> (enable)
To verify that the VLAN configuration is correct, including the mapping between Ethernet, FDDI, and Token Ring, enter the show vlan {trunk | no trunk} command and the show trunk command. After entering the show vlan command, you see this display:

You can configure an FDDI interface to reject the learning of MAC addresses that it previously learned from an Ethernet interface by enabling the fddicheck option to the set bridge command. This feature resolves the problem that occurs when void frames on the FDDI ring and translated Ethernet frames sent by the FDDI interface are received and learned on the same FDDI interface instead of being stripped by the MAC hardware.
To reject MAC address learning, perform this task in privileged mode:
| Task | Command |
|---|---|
| Enable the set bridge fddicheck command. | set bridge fddicheck enable |
After entering the set bridge fddicheck command, you see this display:
Console> (enable) set bridge fddicheck enable FDDICHECK enabled Console> (enable)

Console> (enable)
To increase throughput performance, you can disable the software content-addressable memory (CAM) of the FDDI module. The CAM stores IPX translation information to support automatic packet recognition and translation (APART). Disabling the FDDI module CAM disables APART. Disabling APART automatically disables fddicheck. When APART is disabled, FDDI-to-Ethernet translation values are the settings configured with the set bridge ipx command. However, the Catalyst 5000 series switch Encoded Address Recognition Logic (EARL) CAM continues to provide packet forwarding functionality. To enable fddicheck, first enable APART.
There are some serious drawbacks to disabling the FDDI software CAM. Disabling APART means that only default IPX translations are used. FDDI module hardware filtering is disabled, and all traffic from the FDDI ring is translated and forwarded to the Catalyst backplane before the EARL CAM can filter it. This could greatly impact system performance. Additionally, the fddicheck user-configurable option is disabled when APART is disabled. This feature typically is used in an IP environment.
To disable APART, perform this task in privileged mode:
| Task | Command |
|---|---|
| Disable the software CAM of the FDDI module. | set bridge apart disable |
After entering the set bridge apart disable command, you see this display:
Console> (enable) set bridge apart disable APaRT disabled Console> (enable)
To verify that the software CAM of the FDDI module, APART, and fddicheck command are disabled, enter the show bridge command. After entering this command, you see this display:

Use the ping command to test the connection between a CDDI or FDDI module in the Catalyst 5000 series switch and a host residing anywhere in your network. The ping command pings a host once per second until a normal response is received. The host must be connected to a port with an address on the same IP network. Otherwise, you must configure a static route entry to reach the host network. To stop pinging, enter Ctrl-C.
To check connectivity using the ping command, perform these steps:
| Task | Command |
|---|---|
| Step 1 Send an echo request from the Catalyst 5000 series switch to the host. | ping host |
| Step 2 If the host is unresponsive, check the configuration for the IP address of the Catalyst 5000 series switch and default IP route, if appropriate. | show interface
show ip route |
After entering the ping command, you see this display:
Console> (enable) ping 192.34.56.6192.34.56.6 is alive
Sample results of the ping command follow:
The FDDI module is basically an FDDI-Ethernet translation bridge. It translates packets on the external FDDI ring into Ethernet packets within the Catalyst 5000 series switches. Inside a
Catalyst 5000 series switch, Ethernet VLAN packets are translated into FDDI VLAN packets and encoded in 802.10 format with a SAID value before they are transmitted across an external FDDI trunk to another Catalyst 5000 series switch. The Catalyst 5000 series switch that receives the packets from the trunk decodes the 802.10 format using the SAID value and internally translates the FDDI VLAN packets into Ethernet VLAN packets. Each Ethernet VLAN requires a unique FDDI VLAN translation.
The Catalyst 1200 series switch is hardcoded with a specific VLAN-to-SAID configuration. Therefore, if you are connecting a Catalyst 5000 series switch Ethernet VLAN to a Catalyst 1200 Ethernet VLAN via an FDDI trunk, the SAID value of the FDDI VLAN must be the same value as the Ethernet VLAN. For example, if a Catalyst 1200 Ethernet VLAN value is 20, the translation FDDI VLAN SAID value must be 20.
This section contains examples of single and multiple switch configurations.
Figure 6-2 shows a simple Catalyst 5000 series switch configuration.
The configuration shows a case that includes these elements:
VLAN groups can be set up across multiple Catalyst 5000 series switches without trunking if the switches have any two ports of the same VLAN connected, as shown in the example in Figure 6-3. You need to configure the VLANs individually for both switches using the set vlan command.
This example sets VLAN 10 for the Catalyst 5000 series switch in building A:
System1> (enable) set vlan 10 4/1 VLAN 10 modified. VLAN 1 modified. VLAN Mod/Ports ---- ----------------------- 10 4/1-2
