Hello folks -
I have a couple of Cisco 3550 48 ports switch running 12.1 IOS version. When I issue the command "show arp" on either of the switches, I get a very short arp table which only lists switches that the switch in question is connected to. I do not see any host IP's listed in the ARP table. The switches have atleast 30 hosts individually connected to each of them.
So why would the ARP table be so short?
Thanks for your help!!
you can search by ip address but you need to look at the right device:
you go on the default gateway
sh ip arp x.y.z.w
note the mac address
go on the switch and look for
sh mac-address-table address
so you can find the port where a PC with ip x.y.z.w is connected
Hope to help
