Cisco have always stated that if using dual supervisors they must be
identical (sup version, PFC and MSFC). Anything else is un-supported. I
don't know if will work or not, I haven't tried, but it wouldn't damage the
sup.
Remember that you can purchase a redundant supervisor with MSFC for half
price. It is not licensed to use as a primary so you cannot order one and a
blank chassis and then move it over (without purchasing the upgrade license)
but it does save you a large sum of money. The part numbers are
WS-X6K-S1A-MSFC2/2 and WS-X6K-S2-MSFC2/2.

Subject: OT: MSFC2 redundancy
Anyone,
Sorry for the OT, but couldn't find a definitive answer on CCO.
I've got a client who purchased two 6509 switches, one with redundant sup2's
and the other with redundant sup2's with MSFC2's. This was the config
recommended by our Cisco salesperson. Redundant MSFC2's in each switch were
too pricey. Anyway, my question is can I put a sup2/MSFC2 in each switch's
slot one, with the non-MSFC2 in each slot 2? Cisco was intending both
MSFC2's in the same switch, but if I lose that switch totally, I've lost all
inter-VLAN routing. The two switches will be tied together with multiple
(channeled) gig trunks. I was just going to go ahead and try it, but not at
the risk of damaging a supervisor. Does anyone know if this is supported?
Thanks in advance,
Chuck Church
