Chapter: Token Ring Route Switch Module Commands
Token Ring Route Switch Module Commands
Use the commands in this chapter to configure and monitor the Token Ring Route Switch Module feature. For Token Ring Route Switch Module configuration tasks and examples, refer to the "Configuring Token Ring Route Switch Module" chapter of the Cisco IOS Bridging and IBM Networking Configuration Guide.
clear drip counters
To clear duplicate ring protocol (DRiP) counters from the RSM interfaces, use the clear drip counters privileged EXEC command.
clear drip counters
Syntax Description
This command has no arguments or keywords.
Defaults
Disabled.
Command Modes
Privileged EXEC

This command was introduced. |
Usage Guidelines
Use the clear drip counters command if you want to check whether the router is receiving any packets. The counters will start at 0. If the counters are incrementing, DRiP is active on the router.
Examples
The following example clears DRiP counters:
router# clear drip counters

This command was introduced. |
Usage Guidelines
Valid Token Ring VLAN ID numbers are 2 through 1000.
Routing or bridging to a Token Ring VLAN (TrBRF) on the RSM is done by creating a logical interface to a TrBRF VLAN on the RSM with the interface vlan command. The TrBRF VLAN must be defined on the Supervisor module prior to creating the TrBRF interface on the RSM.
Examples
The interface vlan command is used to configure an RSM Token Ring interface with VLAN 998:
interface vlan998 type trbrf
ip address 5.5.5.1 255.255.255.0
Related Commands
multiring trcrf-vlan
To create a pseudoring on the RSM and to terminate the RIF when routing IP or IPX source-routed traffic on Token Ring VLAN (TrBRF) interfaces, use the multiring trcrf-vlan interface configuration command. To disable the termination of RIFs on the RSM interface, use the no form of this command.
multiring trcrf-vlan vlanid ring-group ring-number
no multiring trcrf-vlan vlanid ring-group ring-number
Syntax Description
vlanid |
VLAN ID number. Valid VLAN ID numbers are 2 through 1000. |
ring-group ring-number |
Keyword that specifies the pseudoring number used to terminate the RIF. |
Defaults
Termination of RIFs is disabled on the RSM interfaces.

This command was introduced. |
Usage Guidelines
Use the multiring command to collect and use RIFs for routed protocols. On an RSM, the multiring command appends RIFs for routed protocols on Token Ring VLAN interfaces. When this command is enabled for a protocol, the RSM will source packets that include information used by source-route bridges. The Token Ring VLAN interfaces on the RSM can connect to an SRB Token Ring network for the protocols specified in the command.
Each Token Ring VLAN interface that is configured with the multiring command on the RSM must also be accompanied by the multiring trcrf-vlan command.
Use the multiring trcrf-vlan command to:
•
Create a pseudoring on which RIFs are terminated for routed protocols.
•Assign the pseudoring to a TrCRF VLAN.
When configuring SRB and IP or IPX routing SR frames on an RSM's TrBRF interface, define both a virtual ring and a pseudoring for the interface using the source-bridge and multiring trcrf-vlan commands. In this case, the VLAN ID used for the TrCRF that corresponds to the virtual ring can be the same as the one used for the pseudoring number. If the VLAN IDs are different, the virtual ring and pseudoring numbers must be different.
Examples
In the following example, the multiring trcrf-vlan command is used to configure a pseudoring with ring number 100 on the RSM:
interface Ethernet 2/2
ip address 4.4.4.1 255.255.255.0
!
interface vlan998 type trbrf
ip address 5.5.5.1 255.255.255.0
multiring trcrf-vlan 200 ring-group 100
multiring all

source-bridge trcrf-vlan
To attach a VLAN to the RSM's virtual ring when source-route bridging, use the source-bridge trcrf-vlan interface configuration command. To disable the attachment of a VLAN to the RSM's virtual ring, use the no form of this command.

Usage Guidelines
Use the source-bridge ring-group command to create a virtual ring for SRB between TrBRF VLANs. Use the source-bridge trcrf-vlan command to assign a TrCRF VLAN ID to the virtual ring.
In SRB and SR/TLB, define a unique TrCRF VLAN ID that corresponds to the virtual ring on the RSM for each TrBRF. Although the VLAN ID for the TrCRF is unique for each TrBRF, the ring number will be the same.
If IP or IPX routing SR frames is required on a TrBRF interface configured for SRB, you must also define a pseudoring for this interface with the multiring trcrf-vlan command. In this case, the VLAN ID used for the TrCRF that corresponds to the virtual ring can be the same as the one used for the pseudoring. If the VLAN IDs are different, the virtual ring and pseudoring numbers must be different.
Examples
The following example shows both SRB and IP routing for SR frames:
source-bridge ring-group 100
interface Token Ring3/1
source-bridge 10 1 100
source-bridge spanning
!
interface vlan999 type trbrf source-bridge trcrf-vlan 400 ring-group 100
source-bridge spanning
multiring all
multiring trcrf-vlan 400 ring-group 100
Note that the ring number must be the same for the source-bridge ring-group, source-bridge, and source-bridge trcrf-vlan commands. In this example, the ring number of the pseudoring also matches the virtual ring number.
