Displaying MCT information

You can display the following information about MCT configuration and operation:

  • Peer and client states
  • State machine information
  • Cluster, peer, and client states
  • MCT-related information for Ethernet interfaces
  • STP information

Displaying peer and client states

Use the show cluster config command to display the peer device and client states.


device# show cluster SXR122 config

cluster SXR122 100
rbridge-id 100
session-vlan 1
keep-alive-vlan 3

client AGG131
rbridge-id 10
client-interface ethernet 1/2/2
deploy
client FOX135
rbridge-id 15
client-interface ethernet 1/2/5

Displaying state machine information

Use the show cluster client command to display additional state machine information, including the reason a local CCEP has gone down. You can specify an individual cluster and client as an option.


device# show cluster 1 client

Cluster 1 1
===================
Rbridge Id: 101, Session Vlan: 3999, Keep-Alive Vlan: 4001
Cluster State: Deploy
Client Isolation Mode: Loose
Configured Member Vlan Range: 100 to 105 
Active Member Vlan Range: 100 to 105 
MCT Peer's Reachability status using Keep-Alive Vlan: Peer Reachable
 Client Info:
 ------------
 Client: c1, rbridge-id: 300, Deployed
 Client Port: 1/3/11
 State: Up
 Number of times Local CCEP down: 0
 Number of times Remote CCEP down: 0
 Number of times Remote Client undeployed: 0
 Total CCRR packets sent: 4
 Total CCRR packets received: 3

The following table shows the messages that may be displayed to explain why the local CCEP is down.

Table 1. Reasons for Local CCEP down

Message for Local CCEP down

Meaning

client-interfaces shutdown

Command is configured.

client-isolation strict

Command is configured.

Deploy mismatch

Client is not deployed remotely.

Slave state

Client is in slave state when CCP is down.

cluster and client undeployed

Neither the cluster nor client is deployed.

cluster undeployed

Cluster is not deployed.

client undeployed

Client is not deployed.

Displaying cluster, peer, and client states

Use the show cluster ccp peer command to display cluster, peer device, and client states. As an option, you can specify an individual cluster and request additional details.


device# show cluster 1 ccp peer
