LOL........ We have enough fun with that when going to new IOS
releases...... LOL.
We went to one IOS release 12.1(19)E9 (I believe E9, but it was 12.1(19)
for sure) to fix that "vunverability" a while back then come to find out
on Native IOS there's a bug where if Power Supply 1 (on the left) shuts
down or loses power (or fails) then the whole chassis reboots instead of
failing over to PS2 (assuming you're not in "combined" power mode)...
Seems to only affect Sup2/MSFC2 under Native IOS.......... We found this
out the HARD way....... I hate finding IOS bugs =)

True, but you miss out on joy of finding all of the new bugs!

Yeah........ We have Sup2/MSFC2 on our 6500s. The Sup720 does a lot in
hardware, but we can't justify spending 25,00-30,000 for new Sup720s
when we're not even toppping out the 256Gbps on the SFM and CPU on the
MSFC2 hardly goes over 3%.

What supervisor engine is in the 6500? The Sup720 will do GRE in
hardware....

LOL......... Well, problem is these little offsites are all in one VLAN
(many of them have just a hub to connects to the router). What we
thought of doing is leaving the 2500 there, and upon installing the
3550, setup a tunnel and send the IPX traffic across the tunnel (there
would be a 6500 on the other end of the tunnel). Doesn't the 6500 have
the process switch all traffic to/from the tunnel interface? Just
thinking about the reality of using that as a workaround.....
Thanks!

Doesn't look like it. Didn't find anything about IPX other than ACL
support in the 12.1.14 config guide. Can't do IRB or CRB either on
those switches, so looks like you're stuck. Maybe create a single VLAN
at those sites for all the IPX devices, and when they no longer need
IPX, move them out of that VLAN to a routed IP-only VLAN.
