Enabling The Ft Vlan; Configuring An Alias Ip Address - Cisco ACE-4710-K9 Administration Manual

Chapter 7 Configuring Redundant ACE Appliances

Enabling the FT VLAN

Configuring an Alias IP Address

OL-11157-01
To enable the FT VLAN, use the no shutdown command in FT interface
configuration mode. The syntax of this command is:
no shutdown
For example, to enable the FT VLAN, enter:
host1/Admin(config-ft-intf)# no shutdown
To disable the FT VLAN after you have enabled it, enter:
host1/Admin(config-ft-intf)# shutdown
When you configure redundancy, configure a VLAN interface that has an alias IP
address that floats between the active and standby appliances. The alias IP address
serves as a shared gateway for the two ACE appliances.
To configure an alias IP address, use the alias command in interface configuration
mode. The syntax of this command is:
alias ip_address netmask
The ip_address netmask arguments specify the IP address and netmask for the
VLAN interface. Enter the IP address and subnet mask in dotted-decimal notation
(for example, 192.168.1.1 255.255.255.0).
For example, to configure an alias IP address, enter:
host1/Admin(config)# interface vlan 100
host1/Admin(config-if)# alias 192.168.12.15 255.255.255.0
To remove an alias IP address, enter:
host1/Admin(config-if)# no alias 192.168.12.15 255.255.255.0
