Priscilla,
A quick look through the relevant chapters of Release 7.3 of the Catalyst
6000 Family Software Configuration Guide reveals nothing on static CAM
entries. Reference to the 'set cam perm' command is made on CCO but makes
no attempt to explain how the behavior of a permanent CAM entry interacts
with the behavior of Etherchannel:

A proof-of-concept test or TAC case may be the only options (hopefully
someone will prove me wrong).
