Hi,
I have a quick question on failover design using two 5540 firewall running in active/standby mode. What is the Pros/Cons of using a crossover cable
between the 2 firewalls VS using a dedicated vlan? I have two 6500 switches with a layer 2 trunk connecting them.
Scenario 1:
I use a dedicated vlan for failover and connect one firewall to Switch A and the other firewall to switch B. If I reboot one of the switches (takes more than 5 minutes), will that caused the firewalls to failover? If so, is there a way to prevent it. I don't want the firewalls to failover unnecessarily.
Scenario 2:
I use a crossover cable between 2 firewalls for failover. One of the drawbacks I heard is that if something goes wrong with the cable, is very hard to troubleshoot.
Any thoughts on which is the prefer failover design?
