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. |

|
cluster-name |
Specify the name of the cluster. |
|
cluster-node-1 fabric-node name |
Specify the name of the first 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. |

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
