I was working with a customer after a switch upgrade and we noticed some ports going off and online.
The natural reaction is to ask, “who is that and is it a problem”.
The new switches weren’t added to the management system, so I showed them how to do it manually and they were very grateful.
So in this video I walk you through how to determine the MAC, IP address and device name.
Here are some of the switch commands I used:
sh log
sh run int gig 2/0/13
sh mac address-table interface gig 2/0/13
sh arp | inc 0026.228e.8c85
conf t
int gig 2/0/13
description Cable E - Sues Desk
exit
exit
sh run int gig 2/0/13
Here is the Microsoft commands
nbtstat -A 10.44.10.132
