Chapter 11 Configuring Failover

Configuring Failover

Step 7 Enable failover.

hostname(config)# failover

Step 8 Power on the secondary unit and enable failover on the unit if it is not already enabled:

hostname(config)# 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 primary console.

Step 9 Save the configuration to Flash memory on the Primary unit. Because the commands entered on the

primary unit are replicated to the secondary unit, the secondary unit also saves its configuration to Flash

memory.

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

Step 10 If necessary, force any failover group that is active on the primary to the active state on the secondary.

To force a failover group to become active on the secondary unit, issue 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 LAN-Based Active/Active Failover

This section describes how to configure Active/Active failover using an Ethernet failover link. When

configuring LAN-based failover, you must bootstrap the secondary device to recognize the failover link

before the secondary device can obtain the running configuration from the primary device.

This section includes the following topics:

• Configure the Primary Unit, page 11-25

• Configure the Secondary Unit, page 11-27

Configure the Primary Unit

To configure the primary unit in an Active/Active failover configuration, perform the following steps:

Step 1 Configure the basic failover parameters in the system execution space.

a. (PIX security appliance platform only) Enable LAN-based failover.

hostname(config)# hostname(config)# failover lan enable

b. Designate the unit as the primary unit.

hostname(config)# failover lan unit primary

c. Specify the failover link.

hostname(config)# failover lan interface

if_name

phy_if

The if_name argument assigns a logical name to the interface specified by the phy_if argument. The

phy_if argument can be the physical port name, such as Ethernet1, or a previously created

subinterface, such as Ethernet0/2.3. This interface should not be used for any other purpose (except,

optionally, the state link).
