Netbios name resolution on 6500 ports

I heard that there was a way that was posted in Packet magazine to find out the device name within CatOS on the actual port. Does anyone know what this command is?

To the best of my knowledge, I know NetBios Name Service Inspection Engine

Enabled by default for UDP ports 137 and 138

Not Configurable

The NetBios inspection engine translates IP addresses in the NetBios name service (NBNS) packets according to the FWSM NAT configuration

Thanks, I looked and the person I heard it from was full of it... The only way to do it is to get the MAC from the CAM table on the switch, go to a router (locally) and do a "show ip arp xxxx.xxxx.xxxx", then take the IP address that is associtated and look it up via "nbtstat -A x.x.x.x"

Thanks again.

Kiwi Enterprises 'CatTool' product will create a report containing this info automatically. It's much easier than gathering various tables and correlating them manually.
