To display a cluster membership for high availability (HA) in a fabric, use the cluster-membership-show command.


Informational Note:  You may configure multiple clusters of switches within a single fabric. However, a switch can participate in only one cluster configuration. For example, switch-1 and switch-2 can participate in cluster-1, and switch-3 and switch-4 can participate in cluster-2, but switch-1 and switch-2 cannot participate in cluster-2 or any other cluster.

Usage   A cluster allows two switches to cooperate in high-availability (HA) deployments. The nodes forming the cluster must be members of the same fabric. Clusters are typically used in conjunction with a virtual link aggregation group (VLAG) allowing links physically connected to two separate switches to appear as a single trunk to a third device. The third device can be a switch, server, or any Ethernet device.

Examples  To display a cluster membership, use the following command:

CLI network-admin@switch > cluster-membership-show
