Configuring Data-Link Switching Plus

Monitoring and Maintaining the DLSw+ Network

Alternately, to verify that DLSw+ is configured, issue the following command in privileged EXEC mode:

Command	Purpose

Router# show running configuration	Displays the running configuration of a device.

The global DLSw+ configuration statements, including the dlsw local-peerstatement, appear in the output before the interface configuration statements. The following sample shows that DLSw+ is configured on router milan:

milan# show run version 12.0

!

hostname Sample

!

source-bridge ring-group 110

dlsw local-peer peer-id 10.1.1.1 promiscuous

!

interface TokenRing0/0 no ip address ring-speed 16 source-bridge 222 1 110 source-bridge spanning

!

Monitoring and Maintaining the DLSw+ Network

To monitor and maintain activity on the DLSw+ network, use one of the following commands in privileged EXEC mode, as needed:

Command	Purpose

Router# show dlsw capabilities interface type	Displays capabilities of a direct-encapsulated remote peer.
number

Router# show dlsw capabilities ip-address	Displays capabilities of a TCP/FST remote peer.
ip-address

Router# show dlsw capabilities local	Displays capabilities of the local peer.

Router# show dlsw circuits	Displays DLSw+ circuit information.

Router# show dlsw fastcache	Displays the fast cache for FST and direct-encapsulated peers.

Router# show dlsw local-circuit	Displays DLSw+ circuit information when doing local
	conversion.

Router# show dlsw peers	Displays DLSw+ peer information.

Router# show dlsw reachability	Displays DLSw+ reachability information.

Router# dlsw disable	Disables and re-enable DLSw+ without altering the configuration.

Router# show dlsw statistics [border-peers]	Displays the number of frames that have been processed in the
	local, remote, and group caches.

Router# clear dlsw circuit	Closes all the DLSw+ circuits1. Also used to reset to zero the
	number of frames that have been processed in the local, remote,
	and group cache.

1. Issuing the clear dlsw circuits command will cause the loss of any associated LLC2 sessions.
