Chapter 11 Configuring Failover

Configuring Failover

c. Enable the interface.

hostname(config)# interface

phy_if

hostname(config-if)# no shutdown

Step 3 (Optional) Designate this unit as the secondary unit.

hostname(config)# failover lan unit secondary

Note This step is optional because by default units are designated as secondary unless previously

configured otherwise.

Step 4 Enable failover.

hostname(config)# failover

After you enable failover, the active unit sends the configuration in running memory to the standby unit.

As the configuration synchronizes, the messages

Beginning configuration replication: Sending to

mate

and End Configuration Replication to mate appear on the active unit console.

Step 5 After the running configuration has completed replication, enter the following command to save the

configuration to Flash memory:

hostname(config)# copy running-config startup-config

Step 6 If necessary, force any failover group that is active on the primary to the active state on the secondary

unit. To force a failover group to become active on the secondary unit, enter the following command in

the system execution space on the primary unit:

hostname# no failover active group

group_id

The group_id argument specifies the group you want to become active on the secondary unit.

Configuring Optional Active/Active Failover Settings

The following optional Active/Active failover settings can be configured when you are initially

configuring failover or after you have already established failover. Unless otherwise noted, the

commands should be entered on the unit that has failover group 1 in the active state.
