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 named, cluster_eng, , use the following command:
CLI network-admin@switch > cluster-modify name cluster_eng cluster-syn-timeout 500ms
