Finding an IP Address

Answered Question
May 5th, 2007

Here's the setup:

One 6509 with FWSM and its 5 security contexts. Hosts are directly connected to the 6509, but are routed through security contexts.

I have an IP address of one of the hosts off the router. The IP obviously wouldn't show up on the ARP table. I get the security context's outside IP when I do a sh ip route x.x.x.x.

So, how do I find out which port contains the host with this IP? Am I out of luck without having a MAC?

Thank you.

I have this problem too.

Hi Greg

Could you not just look at the arp table within the right FWSM context which would give you the mac-address which you could then track down on the 6500 chassis.

Have i misunderstood the issue ?
