I have a c6509 (IOS 5.4(3)) with redundant sups with MSFCs and PFCs. The IOS on the MSFCs is 12.0(7)XE1.
If I upgrade to IOS 12.1(6)E, will I be able to recognize and configure a flex wan module with a PA-A3 OC3 adapter from the MSFC on the primary supervisor (module 15)? My understanding was that I could not use a flexwan in a c6509 with redundant supervisors.
