Configuring Failover
Note
Configure the basic failover parameters in the system execution space.
Step 2
a.
Designate the unit as the primary unit:
hostname(config)# failover lan unit primary
b.
Specify the failover link:
hostname(config)# failover lan interface if_name vlan vlan
The if_name argument assigns a logical name to the interface specified by the vlan argument. This
interface should not be used for any other purpose (except, optionally, the state link).
c.
Specify the failover link active and standby IP addresses:
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 failover link IP address does not change at failover.
The active IP address always stays with the primary unit, while the standby IP address stays with
the secondary unit.
(Optional) To enable Stateful Failover, configure the state link. The state link must be configured on an
Step 3
unused interface.
Specify the interface to be used as the state link:
a.
hostname(config)# failover link if_name [vlan vlan]
The if_name argument assigns a logical name to the interface specified by the vlan argument. This
interface should not be used for any other purpose (except, optionally, the failover link).
Note
Assign an active and standby IP address to the state link.
b.
Note
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 address subnet mask.
The state link IP address does not change at failover. The active IP address always stays with the
primary unit, while the standby IP address stays with the secondary unit.
Configure the failover groups. You can have at most two failover groups. The failover group command
Step 4
creates the specified failover group if it does not exist and enters the failover group configuration mode.

In multiple context mode, you must configure the interface addresses from within each context.
Use the changeto context command to switch between contexts. The command prompt changes
to
hostname/context(config-if)#
If the state link uses the failover link, then you only need to supply the if_name argument.
If the state link uses the failover link, skip this step. You have already defined the failover
link active and standby IP addresses.
, where context is the name of the current context.
