Hi,
I'm not exactly sure about the design rationale behind it but you
won't find the option "mpls" on the ATM main interface. You will only
find that option when you create a sub interface.
It is not necessary to set "mpls atm control-vc x y". It will default
to 0 32 if the opposing switch is also in default. You can set it to
1 64 or a lot of other combinations but just has to match what the
opposing switch is expecting. You verify with the command "show atm
vc".
