cluster-create

To create a new cluster for high availability (HA) in a fabric, use the cluster-create command.

Syntax   cluster-create 

name name-string

Specify the cluster name.

cluster-node-1 fabric-node name

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

cluster-node-2 fabric-node name

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

Any of the following options:

vxlan 0..16777215

Specify the VXLAN ID for cluster over L3.

node1-ip ip-address

Specify the IP address of cluster node 1.

node2-ip ip-address

Specifies the IP address of cluster node 2.

validate|no-validate

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

cluster-sync-timeout 500..20000

Specify the amount of time before a cluster times out during synchronization. The allowed range is between 500ms, and 2000ms.

cluster-sync-offline-count 1..30

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.

Version 7.0.0

The parameters vxlan, node1-ip, node2-ip added.

Usage   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.

            Clustering switch pairs over Layer 3 requires the creation of VXLAN tunnels between the cluster nodes through the intermediate switch(es). The VXLAN tunnels function as virtual cluster links, and carry both control traffic, and data traffic. For further clarification, refer to the Configuration Guide.

Examples  To configure the cluster that includes Leaf1, and Leaf2, use the following command:

CLI (network-admin@switch) > cluster-create name name cluster1 cluster-node-1 Leaf1 cluster-node-2 Leaf2 vxlan 40940 node1-ip 192.168.1.1 node2-ip 192.168.1.2
