Catalyst Switch (6000 series) help!

greetings. i am still a fledgling CCNA...i have inherited a rather interesting "mess". i have clients plugged into a 6000 series switch. however the cables are a mess and a half...and no documentation too boot. i am trying to figure out which ip address goes to which port (for the wires are not plugged in where the computer says they are)...is there a specific command that will show me which port is assigned which ip address? i thank you in advance for any assistance.

Would you be able to post the configuration of the switch. Can you also post the output to the, show mod

command, from the switch.

Campus Manager can help you with this giving you an overview of both layer 2 and 3. You can export the CM Toplogy Manager's maps in Visio format for documentation.

Jonathan,

Just so you know, you can run a show cam dyn 3/14 (for port 3/14) and it will show you the mac that is in the arp cache for that port. Then you can telnet to the router on that subnet, run a sh arp, and match mac to ip. It's kind of tedious but I've had to do it my self.

Re: Catalyst Switch (6000 series) help!

If your Cat6k has an MSFC (router) you can session into the module, or telnet if there is an ip address assigned to the management vlan. Once telnetted into the MSFC you can use the command "show ip arp" and use the IP address of the workstation in question. This will give you the mac address of the workstation, you can then use the "show cam mac_addr" command with the mac_addr in the format of 00-12-ba.... (using the mac address you learned earlier). This will identify the port the workstation is connected to, or the port of the trunk of the switch that the workstation is plugged into if trunking.

The "show ip arp" should also work on a router plugged into the switch if you don't have an MSFC configured for routing.

Hope this helps
