Currently when I need to find a device on a switch that I dont know where it is plugged in, I go through this process.
Say you want to find a machine with the IP address of 192.168.2.7 From the enable prompt you would type in
"sh arp | include 192.168.2.7 "
This would result in this if found on that switch
Internet 192.168.2.7 4 000b.cdaf.1d29 ARPA Vlan192
From here, to find the port you would type in
"sh mac address-table dynamic | include 000b.cdaf.1d29"
And the results, if found would be like this
"192 000b.cdaf.1d29 dynamic ip GigabitEthernet7/10"
Can anyone recommend a easier fast way to do this ON THE SWITCH, without using a third party application.
