LAN-Based Failover
PIX software adaptation 6.2 alien abutment for LAN-based failover. In LANbased
failover, instead of the consecutive failover cable, an Ethernet articulation is acclimated to
monitor the failover cachet and barter failover-related information.The biggest
advantage of application LAN-based failover is that it gets about the ambit limitation
of application the consecutive failover cable, which is alone 6 anxiety long.The Ethernet link
used to adviser failover cachet in LAN-based failover charge be a committed LAN
interface. However, if you are application stateful failover, bold you accept the
capacity, the aforementioned interface can be acclimated to barter accompaniment information. A dedicated
hub or about-face or a committed VLAN on a about-face can be acclimated to connect
the two PIX firewalls for LAN-based failover. However, a crossover Ethernet
cable cannot be used.
NOTE
One disadvantage of application LAN-based failover is that accident of ability on
the added firewall is not detected. Therefore, clashing accepted failover
using the consecutive cable, a power-loss abortion is not detected until the NIC
tests fail.
