Chapter 6 Clustering Switches
Instead of using CMS to add members to the cluster, you can use the cluster member global
configuration command from the cluster command switch. Use the password option in this command if
the candidate switch has a password.
You can select 1 or more switches as long as the total number of switches in the cluster does not
exceed 16 (this includes the cluster command switch). When a cluster has 16 members, the Add to
Cluster option is not available for that cluster. In this case, you must remove a cluster member switch
before adding a new one.
If a password has been configured on a candidate switch, you are prompted to enter it before it can be
added it to the cluster. If the candidate switch does not have a password, any entry is ignored.
If multiple candidates switches have the same password, you can select them as a group, and add them
at the same time.
If a candidate switch in the group has a password different from the group, only that specific candidate
switch is not added to the cluster.
When a candidate switch joins a cluster, it inherits the command-switch password. For more information
about setting passwords, see the
For additional authentication considerations in switch clusters, see the
