Chapter 7 Configuring Redundant ACE Appliances
Configuring Redundancy
Enabling the FT VLAN
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
Configuring an Alias IP Address
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
