For more information about switch stacks, see
TACACS+ and RADIUS
If Terminal Access Controller Access Control System Plus (TACACS+) is configured on a cluster
member, it must be configured on all cluster members. Similarly, if RADIUS is configured on a cluster
member, it must be configured on all cluster members. Further, the same switch cluster cannot have some
members configured with TACACS+ and other members configured with RADIUS.
For more information about TACACS+, see the

section on page

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.
Using the CLI to Manage Switch Clusters
You can configure cluster member switches from the CLI by first logging into the cluster command
switch. Enter the rcommand user EXEC command and the cluster member switch number to start a
Telnet session (through a console or Telnet connection) and to access the cluster member switch CLI.
The command mode changes, and the Cisco IOS commands operate as usual. Enter the exit privileged
EXEC command on the cluster member switch to return to the command-switch CLI.
This example shows how to log into member-switch 3 from the command-switch CLI:
switch# rcommand 3
If you do not know the member-switch number, enter the show cluster members privileged EXEC
command on the cluster command switch. For more information about the rcommand command and all
other cluster commands, see the switch command reference.
The Telnet session accesses the member-switch CLI at the same privilege level as on the cluster
command switch. The Cisco IOS commands then operate as usual. For instructions on configuring the
switch for a Telnet session, see the
The CLI supports creating and maintaining switch clusters with up to 16 switch stacks. For more

If a cluster member switch stack reloads and a new stack master is elected, the switch stack loses
connectivity with the cluster command switch. You must add the switch stack back to the switch
cluster.
If a cluster command switch stack reloads, and the original stack master is not re-elected, you must
rebuild the entire switch cluster.
