Chapter 61: Switch Cluster Commands

Switch Clustering is a method of grouping switches together to enable centralized management through a single unit. A switch cluster has a “Commander” unit that is used to manage all other “Member” switches in the cluster. The management station uses Telnet to communicate directly with the Commander throught its IP address, and the Commander manages Member switches using cluster “internal” IP addresses. There can be up to 36 Member switches in one cluster. Cluster switches are limited to within a single IP subnet.

Command Usage

•To create a switch cluster, first be sure that clustering is enabled on the switch (the default is enabled), then set the switch as a Cluster Commander. Set a Cluster IP Pool that does not conflict with any other IP subnets in the network. Cluster IP addresses are assigned to switches when they become Members and are used for communication between Member switches and the Commander.

•Switch clusters are limited to a single IP subnet (Layer 2 domain).

•A switch can only be a Member of one cluster.
