finding port info on 6509 running IOS

[mwidina]

Are there any commands that I could issue to the switch that would give me back the port info if I know either the IP address of a workstation or it's MAC address? Meaning I want to know where a particular workstation is plugged in without tracing cables.

[state]

sh arp

This will give you the stations IP adress, MAC address and the VLAN it belongs to. Once you have this info you can use the

sh mac-address-table vlan #

This will show you the MAC address and which port it's connected to.

sh mac-address-table ?

This will give you all kinds of options you can use to drill down to whatever your needs may be.

Hope this helps.

sh mac-add add 00d0.d456.0000

This will give you the exact port number of where that mac address it on the switch. I use this one all the time.

I would suggest putting a description on the port when you find it. Very helpful in the future.

thanks
