George:
I have a few Flexwan modules running in Cat6509s. Let me first start by
saying that trying to run the two MSFCs as completely separate routers is
not recommended and not supported by Cisco. Everything I read about the
MSFCs (and especially when using a FlexWAN module) is that the two MSFCs
must have identical configs. Try typing this on your MSFC:
show redundancy
you should see something like this:
MSFC#sho redundancy
Designated Router: 1 Non-designated Router: 2
Redundancy Status: designated
When the switch/msfc boots up, it has to pick a designated and
non-designated MSFC. You will see that your Flexwan interface (in my case
it is a POS OC-3 card) will map to the designated msfc.
Cisco gives you a few options here:
#1. You can set up config synch and use the alt commands
#2. You can set up SRM, which is new, but seems to work well.
or
#3. You can continue to run it like it is, but you are asking for trouble.
The Flexwan, MSFC, SUP and PFC all need to work together. If you keep
resetting the designated MSFC and the Non-designated one has a different
config, you will introduce instability. Trust me on this.

Subject: FlexWAN & MSFC mapping
Hi,
Anyone know if this is possible.
We have 2 Supervisor cards with MSFC's and would like to run them
separately. We also have a FlexWAN card. When the one msfc is reloaded the
flexWAN is mapped to the other MSFC. How do we make it switch back to the
orignal MSFC without reloading the one that the FlexWAN is currently mapped
to.
Thanks
George
