Thanks Brian ! I tested service-policy input with the following sceneriso:
applied bandwidth statment to the policy map-----------> and agree with you
input won't be accepted
applied priority statement tg othe policy map-------------> and agree with
you input won't be accepted.
I applied policing/cir to the policy map --------------------> and still
input was not accepted.
Shouldn't Policy/CIR allow you to configure interface with service-policy
input.
Regards,
Ahmed
