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
The following example displays 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 1/1/1 peer 172.17.0.2 rbridge-id 101 icl SXR122-MCT deploy client KL134 rbridge-id 14 client-interface ethernet 1/1/23 deploy client AGG131 rbridge-id 10 client-interface ethernet 1/2/2 deploy client FOX135 rbridge-id 15 client-interface ethernet 1/2/5 deploy
The following example displays 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.

The following example displays cluster, peer device, and client states. As an option, you can specify an individual cluster and request additional details.
