Configuring an Alias IP Address

This section describes how to configure an alias IP address. When you configure redundancy, configure
a VLAN interface that has an alias IP address thatfloats between the active and standby appliances. The
alias IP address serves as a shared gateway for the two ACE appliances.
Detailed Steps
Command
Step 1
config
Example:
host1/Admin# config
host1/Admin#(config)#
Step 2
interface vlan vlan_id
Example:
host1/Admin(config)# interface vlan 100
host1/Admin(config-if)#
Step 3
alias ip_address netmask
Example:
host1/Admin(config-if)# alias 192.168.1.1
255.255.255.0
