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.
To clear duplicate ring protocol (DRiP) counters from the RSM interfaces, use the clear drip counters privileged EXEC command.
clear drip countersSyntax Description
This command has no arguments or keywords.
Defaults
Disabled.

Privileged EXEC
Command History

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

Description
To configure a Token Ring or Ethernet interface on the RSM, use the interface vlan interface configuration command.
interface vlan vlanid type [trbrf | ethernet]
Syntax Description
vlanid Unique VLAN ID number used to create a VLAN. trbrf | ethernet (Optional) RSM Interface type.
Defaults
The RSM interfaces are not configured.

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
Clears DRiP counters. Creates a pseudo-ring to terminate the RIF for source-routed traffic and assigns it to a VLAN. Attaches a TrCRF VLAN to the virtual ring of the router. Displays the status of the DRiP database
Command
Description
To create a pseudo ring 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. Use the no form of this command to disable the termination of RIFs on the RSM interface.
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 pseudo ring number used to terminate the RIF.
Defaults
Termination of RIFs is disabled on the RSM interfaces.

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:
When configuring SRB and IP or IPX routing SR frames on an RSM's TrBRF interface, define both a virtual ring and a pseudo-ring 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 pseudo ring number. If the VLAN IDs are different, the virtual ring and pseudo-ring numbers must be different.
Examples
In the following example, the multiring trcrf-vlan command is used to configure a pseudo-ring 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

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

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 pseudo-ring 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 pseudo-ring. If the VLAN IDs are different, the virtual ring and pseudo-ring numbers must be different.
Examples
An example with both SRB and IP routing for SR frames is shown below:
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 pseudo ring also matches the virtual ring number.
