How to Configure a Switch Cluster

DETAILED STEPS FROM THE CLI

 

Command or Action

Purpose

Step 1

 

 

cluster member

Adds members to the cluster.

 

 

• The example shows how to add a switch with MAC

 

Example:

address 00E0.1E00.3333 to the cluster. This switch

 

Switch(config)# cluster member mac-address

does not have a password. The cluster command switch

 

00E0.1E00.3333

selects the next available member number and assigns

 

 

it to the switch that is joining the cluster.

Step 2

 

 

password

Allows you to enter a password if the candidate service

 

 

module has a password.

 

Example:

• The example shows how to add a switch as member 2

 

Switch(config)# cluster member 2 mac-address

with MAC address 00E0.1E00.2222 and the password

 

00E0.1E00.2222 password key vlan 3

key to a cluster. The cluster command switch adds the

 

 

candidate to the cluster through VLAN 3.

 

 

 

Creating a Cluster Standby Group

This section describes how to add Cisco EtherSwitch service modules to a cluster standby group and to bind the cluster standby group to a cluster.

Note Standby cluster command Cisco EtherSwitch service modules must be the same type of service modules as the cluster command service module.

These abbreviations are appended to the Cisco EtherSwitch service module hostnames in the standby command group list to show their eligibility or status in the cluster standby group:

•AC—Active cluster command service module

•SC—Standby cluster command service module

•PC—Member of the cluster standby group but not the standby cluster command service module

•HC—Candidate service module that can be added to the cluster standby group

•CC—Cluster command service module when HSRP is disabled

The Standby Command Configuration window uses the default values for the preempt and name commands that you have set by using Network Assistant or the CLI. If you use this window to create the standby group, all Cisco EtherSwitch service modules in the group have the preempt command enabled. You must also provide a name for the group.

Note 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.
