ls there a Linux shell command which maps mac to ip addresses ie arp?

Question

l trying to collect ip information from my switches, although l can get it from switches console, l just want to feel more geek by doing it from my Ubuntu laptop?

On the Extreme switches, the command is Show iparp and on cisco switches its Show ip arp.

Answer 1

i usually use arp -a or arp -i eth1 where as eth1 is my NIC facing the LAN


again so you can use wireshark & capture any details you want that you could get from the switch. Wireshark will make you feel so good and it will bring everything to your finger tips. I used since the days it was called ethereal, guys at mweb used to change their ip's & hostnames that would kaak on my routing and with ethereal i could detect ip changes or hostname changes as and when it happened.
