Creating a Switch Cluster

You can globally change the management VLAN for the cluster as long as each member switch has either
a trunk connection or connection to the new command-switch management VLAN. Use the cluster
management vlan global configuration command from the command switch to change the current
management VLAN of the cluster to a different management VLAN.
If you add a new switch to an existing cluster and the cluster is using a management VLAN other than
the default VLAN 1, the command switch automatically senses that the new switch has a different
management VLAN and has not been configured. The command switch issues commands to change the
management VLAN of the new switch to match the one in use by the cluster. This automatic change of
the VLAN only occurs for new, out-of-box switches that do not have a config.text file and for which there
have been no changes to the running configuration.
For more information about changing the management VLAN, see the
VLAN for a New Switch" section on page

LRE Profiles

A configuration conflict occurs if a switch cluster has LRE switches using both private and public
profiles. If one LRE switch in a cluster is assigned a public profile, all LRE switches in that cluster must
have that same public profile. Before you add an LRE switch to a cluster, make sure that you assign it
the same public profile used by other LRE switches in the cluster.
A cluster can have a mix of LRE switches using different private profiles.
For more information about the Catalyst 2900 LRE XL switches and LRE technology, refer to the
Catalyst 2900 XL and Catalyst 3500 XL documentation for Cisco IOS Release 12.0(5)WC2.

Availability of Switch-Specific Features in Switch Clusters

The menu bar on the command switch displays all options available from the switch cluster. Therefore,
features specific to a member switch are available from the command-switch menu bar. For example,
Device > LRE Profile appears in the command-switch menu bar when at least one
Catalyst 2900 LRE XL switch is in the cluster.
