Chapter 5 Clustering Switches

Network Port

A network port cannot link cluster members. For more information about the network port, see the
"Enabling a Network Port" section on page

NAT Commands

When you create a cluster, Network Address Translation (NAT) commands are added to the
configuration file of the command switch. Do not remove these commands.

LRE Profiles

A configuration conflict occurs if a switch cluster has Long-Reach Ethernet (LRE) switches that use 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 that use different private profiles.

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.

Creating a Switch Cluster

Using CMS to create a cluster is easier than using the CLI commands. This section provides this
