	You are seeing the MFSC memory.

	You need to login to to the supervisor
(do a sh mod to determine the slot)

Then:

Router#attach 5
Trying Switch ...
Entering CONSOLE for Switch
Type "^C^C^C" to end this session


Router-sp#

	You'll be able to see you're on the supervisor there.

	a quick "sh ver" on the sup will indicate the amount of
memory installed.

Evidentally, you can't execute-on (or I don't have the syntax
right)

Router#execute-on ?
  <1-9>      slot number
  all-mwams  All MWAM slots in chassis

Router#execute-on 5 ?
% Unrecognized command

	You can also do this:

Router#remote login switch
