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.
Note Both chassis must be the same model number, have the same amount of RAM, Flash 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 appliances, so that there is no traffic flow between them. If the failover

cable is connected to the PIX security appliance, disconnect it.
Configure the PIX security appliances for LAN-based failover. Refer to the chapter on configuring

A dedicated LAN interface and a dedicated switch (or VLAN) is required to implement
LAN-based failover. You cannot use a crossover Ethernet cable to connect the two PIX security
appliances.
