cluster-create

To create a new cluster for high availability (HA) in a fabric, use the cluster-create 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-create name name-string cluster-node-1 cluster-node-1cluster-node-2 cluster-node-2 [validate|no-validate]

cluster-name

Specify the name of the cluster.

cluster-node-1 fabric-node name

Specify the name of the first switch in the cluster.

cluster-node-2 fabric-node name

Specify the name of the second switch in the cluster.

Any of the following options:

validate|no-validate

Validate the inter-switch links and state of the switches in the cluster.

cluster-sync-timeout milliseconds

Specify the amount of time before a cluster times out during synchronization. Specify a time between 500 and 2000 ms.

cluster-sync-offline-count number

Specify the number of missed synchronizations before the cluster goes offline.

Defaults   None

Access   CLI

History   

Version 1.2

Command introduced.

Version 2.1

The parameter, private-link, added.

Version 2.2

The parameter, private-link, deprecated.

Version 3.0.0

The parameters, cluster-sync-timeout and cluster-sync-offline-count added.

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 create a cluster named, cluster_eng, using an interswitch link or trunk between two cluster nodes, switch_a and switch_b, and available to other network traffic, use the following command:

CLI network-admin@switch > cluster-create name cluster_eng cluster-node-1 switch_a cluster-node-2 validate
