Port tracking by IP address

We use 6509 switches in our core with 5500's as floor switches. The 6509's both have MSFC's for routing.

Is there an easy way to track down an IP address to a port on a particular switch. Currently, I capture the ARP table listing from the MSFC's to a text file, then associate the IP address with a MAC address, then use SH CAM to track down the MAC address on our infrastructure. A simple "sh me which port this IP address originates from" command would be great.

You need to use some greens. (Buy CW2000/LMS).

There you have the automatic correlation between mac- ip-port-device-...-....

You can also write scripts that capture the arp table, store it in a database and you can then run querys (ex. through a web interface). The scripts can also capture mac address from the sh cam and link them to the IP address. If you have the greens, it will be much simpler.
