“Configuring the Secondary Unit” section on page 62-11

.

Configuring the Primary Unit

Follow the steps in this section to configure the primary unit in a LAN-based, Active/Standby failover
configuration. These steps provide the minimum configuration needed to enable failover on the primary
unit.

Restrictions

Do not configure an IP address in interface configuration mode for the Stateful Failover link if you are
going to use a dedicated Stateful Failover interface. You use the failover interface ip command to
configure a dedicated Stateful Failover interface in a later step.

Prerequisites

Configure standby addresses for all IP addresses according to

Chapter 8, “Completing Interface

Configuration (Routed Mode),”

or

Chapter 9, “Completing Interface Configuration

(Transparent Mode).”

For multiple context mode, complete this procedure in the system execution space. To change from
the context to the system execution space, enter the changeto system command.
