Task Flow for Configuring Redundancy

Follow these steps to configure redundancy on the ACE:
If you are operating in multiple contexts, observe the CLI prompt to verify that you are operating in the
Step 1
desired context. If necessary, change to the correct context.
host1/Admin# changeto C1
host1/C1#
The rest of the examples in this table use the Admin context, unless otherwise specified. For details on
creating contexts, see the Cisco 4700 Series Application Control Engine Appliance Virtualization
Configuration Guide.
Enter configuration mode.
Step 2
host1/Admin# config
host1/Admin(config)#
Configure one of the Ethernet ports on the ACE for fault tolerance using a dedicated fault-tolerant (FT)
Step 3
VLAN for communication between the members of an FT group.
host1/Admin(config-if)# ft-port vlan 200
Configure a dedicated FT VLAN for communication between the members of the FT group. This FT
Step 4
VLAN is global and is shared by all contexts. Specify the IP address and netmask of the FT VLAN and
the IP address and netmask of the remote peer.
host1/Admin(config)# ft interface vlan 200
host1/Admin(config-ft-intf)# ip address 192.168.12.1 255.255.255.0
host1/Admin(config-ft-intf)# peer ip address 192.168.12.15 255.255.255.0
host1/Admin(config-ft-intf)# no shutdown
host1/Admin(config-ft-intf)# exit
Configure a VLAN with an alias IP address that floats between the active and standby ACEs and serves
Step 5
as a shared gateway for the two devices.
host1/Admin(config)# interface vlan 100
