This is normal. You need to copy the POS configuration into the startup
config of the second MSFC. When the switch over occurs then the second MSFC
will see the FlexWAN interfaces and load the config.
What you must not do is do a write mem on the second MSFC because it will
not have the FlexWAN config in it's running config and will erase it from
the startup config. Any changes that you make to the primary MSFC should be
made to the secondary's running config and also changed in it's startup
config file via TFTP.
There are different ways to overcome this. You can have the second MSFC as a
standby (i.e. not running) and once the primary fails it loads up and
becomes the primary. This gets around the config issue as any changes
written to memory on the primary are copied over to the secondary. The
Native IOS solution also works in this way. The only problem with this is
both routers are not active as the same time so you cannot do load-balancing
with HSRP etc and I think the fail over takes longer.

Subject: 6500 Flexwan modules & Msfc
Hi all:
We have a 6500 switch with a flex wan card to support POS interfaces. We
are using catos 6.3.8 and IOS (msfc) 12.1.8bE11. The problem we have is
that the POS interface only appears in one of the two msfcs we have in the
chassis (we have two SP cards & 2 msfcs).
Anyone knows if this is normal? Supposing the main SP goes down, then
you`d need to configure the second msfcs for operating with the pos
interfaces. It seems a very limited implementation, if this is so.
Any help would be apreciated.
Regards
