  • Finding an IP Address

    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.

    Hi parklabel,

    Good question but I don't have any 6509 experience.

    Does anyone out there have any experience on the "big box" to help out our friend????

      Show arp on the firewall to get the mac and then paste that into sh mac-addr | inc blah where blah is the mac in the dotted (0000.1111.2222) format on the 6500. Should give you the port.
