Chapter 6 Clustering Switches
Creating a Switch Cluster
Figure 6-12 Using the Topology View to Add Member Switches
Creating a Cluster Standby Group
The cluster standby group members must meet the requirements described in the “Standby Command
Switch Characteristics” section on page 6-3 and “HSRP and Standby Command Switches” section on
page 6-12. To create a cluster standby group, select Cluster > Standby Command Switches
(Figure 6-13).
Instead of using CMS to add switches to a standby group and to bind the standby group to a cluster, you
can use the standby ip, the standby name, and the standby priority interface configuration commands
and the cluster standby group global configuration command.
• When the command switch is a Catalyst 3550 switch, all standby command switches must be
Catalyst 3550 switches.
• When the command switch is a Catalyst 2955 switch, all standby command switches must be
Catalyst 2955 switches.
• When the command switch is a Catalyst 2950 LRE switch, all standby command switches must be
Catalyst 2950 LRE switches.
• When the command switch is a non-LRE Catalyst 2950 switch running Cisco IOS
Release 12.1(9)EA1 or later, all standby command switches must be non-LRE Catalyst 2950
switches running Cisco IOS Release 12.1(9)EA1 or later.
Thin line means a
