My guess is that there really is only one Ethernet interface, but two 
cabling options: AUI or RJ-45.

Use the media-type {10Baset | aui | auto-select} command to select the one 
you want. Notice that supposedly auto select should figure out which one 
you're using but field experience says that it doesn't sometimes.

Check CCO to make sure on this, but that's probably what's happening.
