Finding ARP entries through CATOS

[Basher]

Good morning all.

I am using a Cisco 4006 switch running CATOS, what I need to do is find out which port has a machine on with a certain IP address so I can shut it down (the port). Normally I'd do this by looking through the ARP table and finding the port relating to the IP, however I'm not so hot with CATOS, all i get when I issue a sh arp command is one IP address, which is weird as this is a fully populated switch with several ethernet switching modules.

Any ideas?

How about sh cam dynamic <VLAN>as this will show all ports and addresses per vlan.

I don't have any kit running CATOS to test it on but one of my colleagues suggested it.

the single ip address you see will be the managment interface (sc0), it'll only have an arp table if its a L3 switch, (L3 supervisor, or seperate RSM) in which case you'll need to look there for arp tables. The cam table in a L2 4006 will only show mac addresses and vlans.
