Displaying MCT 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
icl SXR122-MCT ethernet 1/1
peer 172.17.0.2 rbridge-id 101 icl SXR122-MCT
deploy
client KL134
rbridge-id 14
client-interface ethernet 1/23
deploy
client AGG131
rbridge-id 10
client-interface ethernet 12/2
deploy
client FOX135
rbridge-id 15
client-interface ethernet 1/25
deploy

Syntax: show cluster cluster-name/cluster-id config

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

Active Member Vlan Range: 100 to 105 
MCT Peer's Reachability status using Keep-Alive Vlan: Peer Reachable
 Client Info:

 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

Syntax: show cluster cluster_name/cluster_id client [client_name/client_RbridgeID ]

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

Table 16 Reasons for Local CCEP down
Reason 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
...
