[c-nsp] No warning in conf t ?

[Phibee Network Operation Center]

Hi

I want know if it's possible to say at the IOS that don't sent "Warning".

Ex:
     C7606(config)#no interface Serial0/1/0.1 multipoint
     Not all config may be removed and may reappear after reactivating 
the sub-interface

I want don't see "Not all config may be removed and may reappear after 
reactivating the sub-interface"
that he delete the interface without errors because it's a perl script.

I want remove all config systematiquely

Thanks for your help
