Why does the Cam Table on a Catalyst 5500 Switch Show Out of Range Ports?

<pre>When I issue the following command on my Catalyst 5500 switch:

sh cam dynamic 00-10-2f-f9-78-00

I get this output:

<ul>

147 00-10-2f-f9-78-00 R 2/1-4 [ALL]

145 00-10-2f-f9-78-00 R 16/64 [ALL]

1 00-10-2f-f9-78-00 R 5/1 [ALL]

3 00-10-2f-f9-78-00 R 5/1 [ALL]

7 00-10-2f-f9-78-00 5/5 [ALL]

131 00-10-2f-f9-78-00 5/1 [ALL]

137 00-10-2f-f9-78-00 R 5/1 [ALL]</ul>

The entry for VLAN 145 shows that it is associated with a non-existent port number 16/64. How do I interpret this?

The address is the MAC address on a neighboring Catalyst 5500 switch with a RSM module. The rest of the ports are trunks on the local Catalyst.</pre>

16/64 must be an aggregate port (port-channel interface).  Use the command show agport to find out what port-channel is referenced by 16/64.  The RSM uses the same mac for all VLANs.
