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

Syntax   cluster-membership-modify

name name-string

Specify the name of the cluster membership.


fabric-node name

Specify the name of the first fabric node in the cluster.


fabric-node name

Specify the name of the second fabric node in the cluster.

Defaults   None

Access   CLI


Version 2.5.0

Command introduced.

Version 3.0.0

The parameter validate|no-validate deprecated.

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

Examples  To modify a cluster membership, cluster_eng, using an interswitch link or trunk between two cluster nodes, fabric_a and fabric_b, and is available to other network traffic, use the following command:

CLI network-admin@switch > cluster-create name cluster_eng cluster-node-1 fabric_a cluster-node-2 fabric_b
