I have understood that layer 2 switch is only interested in MAC addresses so why do switches keep an ARP table?
We have some issues with a client who has connected a switch between multiple WAN connections and an ISA server. Each of the WAN devices is on a separate subnet, some are offering DHCP. My common sense tells me that this is not a good setup as there is one broadcast domain and multiple subnets attached to it. I would appreciate any pointers to understand better why this is not working well.
