Installing LAN-Based Failover
Installing LAN-Based Failover
LAN-based failover supports failover between two units connected over a dedicated Ethernet interface.
LAN-based failover eliminates the need for a special failover cable and overcomes the distance
limitations imposed by the failover cable.
Both PIX security appliances must be the same model number, have the same amount of RAM, Flash
Note
memory, number and type of interfaces, and be running the same software version.
To set up a LAN-based failover connection, perform the following steps:
Disconnect both PIX security appliance, so that there is no traffic flow between them. If the failover
Step 1
cable is connected to the PIX security appliance, disconnect it.
Configure the PIX security appliance for LAN-based failover. Refer to the chapter on configuring
Step 2
LAN-based failover in the configuration guide online at:
