We have two Catalyst 4006 switches with the Layer 3 services card. Both switches are trunked over the two GigE ports on the supervisor. I have added a permanent cam entry on each switch for a multicast MAC address sending it to port(s) 2/47 and 1/1-2 (trunk ports) When I reboot switch number one it's almost like the CAM entry disapears, when you do a show config, it is still in the config, doing a show cam perm also shows the entry. When I do a clear cam perm and then re-add the two entries it woulds fine. The other switch does not have this problem. Any ideas?
