If I have an ip address of a server on a remote switch how do I find out what port it is on?? I know I can get the Mac of the server and look at the Mac table but what if I only have ip. I used to get this but can't remember what I did. I console into switch and ping it but no entries in arp table.

Thanks

With ip only:

Log on the L3 device and do 'show ip arp --> gets you MAC

If you have only one switch and router then you know the exercise.

Thanks!!!!  I knew I was missing something and just forgot.....need to be on the L3 not L2 switch....sometime the most obvious is overlooked.   Thanks for the kick in the butt.....:-))
