Chapter 5 Clustering Switches

Creating a Cluster Standby Group

The cluster standby group members must meet the requirements described in the
Command Switch Characteristics" section on page 5-3
Switches" section on page
Switches
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.
Standby cluster command switches must be the same type of switches as the cluster command switch.
Note
For example, if the cluster command switch is a Catalyst 3560 switch, the standby cluster command
switches must also be Catalyst 3560 switches. Refer to the switch configuration guide of other
cluster-capable switches for their requirements on standby cluster command switches.
These abbreviations are appended to the switch host names in the Standby Command Group list to show
their eligibility or status in the cluster standby group:
•
•
•
•

You must enter a virtual IP address for the cluster standby group. This address must be in the same subnet
as the IP addresses of the switch. The group number must be unique within the IP subnet. It can be from
0 to 255, and the default is 0. The group name can have up to 31 characters.
The Standby Command Configuration window uses the default values for the preempt and name
commands that you have set by using the CLI. If you use this window to create the standby group, all
switches in the group have the preempt command enabled. You must also provide a name for the group.
The HSRP standby hold time interval should be greater than or equal to three times the hello time

interval. The default HSRP standby hold time interval is 10 seconds. The default HSRP standby hello
time interval is 3 seconds. For more information about the standby hold time and standby hello time
intervals, see the

(Figure 5-11).
