Chapter 11 Configuring Failover

Configuring Failover

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.

b. Assign an active and standby IP address to the state link:

hostname(config)# failover interface ip

if_name ip_addr mask

standby

ip_addr

The standby IP address must be in the same subnet as the active IP address. You do not need to

identify the standby IP address subnet mask.

The state link IP address and MAC address do not change at failover. The active IP address always

stays with the primary unit, while the standby IP address stays with the secondary unit.

c. Enable the interface:

hostname(config)# interface

phy_if

hostname(config-if)# no shutdown

Step 5 Enable failover:

hostname(config)# failover

Step 6 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 7 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

Configuring LAN-Based Active/Standby Failover

This section describes how to configure Active/Standby 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.

Note If you are changing from cable-based failover to LAN-based failover, you can skip any steps, such as

assigning the active and standby IP addresses for each interface, that you completed for the cable-based

failover configuration.

This section includes the following topics:

• Configuring the Primary Unit, page 11-18

• Configuring the Secondary Unit, page 11-19
