LRE Profiles

In Cisco IOS Release 12.1(14)EA1 or later, the Catalyst 2950 LRE switches do not support public
profiles.
In software releases earlier than Cisco IOS Release 12.1(14)EA1, a configuration conflict occurs if a
switch cluster has LRE switches that use both private and public profiles. If one LRE switch in a cluster
is assigned a public profile, all the 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 or Catalyst 2950 LRE switch is in the cluster.

If your cluster has these member switches running earlier software releases and if you have
read-only access to these member switches, some configuration windows for those switches display
incomplete information:
– Catalyst 2900 XL or Catalyst 3500 XL member switches running Cisco IOS
Release 12.0(5)WC2 or earlier
– Non-LRE Catalyst 2950 member switches running Cisco IOS Release 12.0(5)WC2 or earlier
– Catalyst 3550 member switches running Cisco IOS Release 12.1(6)EA1 or earlier
For more information about this limitation, refer to the release notes.
These switches do not support read-only mode on CMS:
Catalyst 1900 and Catalyst 2820
–
Catalyst 2900 XL switches with 4-MB CPU DRAM
–
In read-only mode, these switches appear as unavailable devices and cannot be configured from
CMS.
