This section describes the SME cluster quorum and the process for electing the master switch in a cluster.

• Master Switch Election

Node ID

Every switch in a cluster has a node ID. SME assigns a node ID to every new switch as it is added to the cluster. The switch where the cluster is created is assigned the node ID of 1. This is the master switch. When a new switch is added to the cluster, it is assigned the next available higher node ID. For example, when a second switch is added to the cluster it gets the node ID of 2 and the third switch gets the node ID of 3, and so on.

Cluster View

The cluster view is the set of switches that are part of the operational cluster.
