hello , thanks for reply
1 Po1(RU) Te0/0/0(P) Te0/0/1(P) Te2/0/0(P) Te2/0/1(P)
so i can apply it in each port in EtherChannel

Don't recall if there are differences for whatever IOS version you're running on your ASR, but for use in a policy-map class, you shouldn't need to enable NBAR protocol-discovery to match "known" (by NBAR) protocols.

Second, I recall (?) later IOSs require a feature license, or feature set, for NBAR.
