Mike,

Yes, it is my understanding that "match input-interface" only works with
traffic arriving on the referenced interfaces. Such a class-map would
likely be in a policy applied outbound on a different interface.

Hi Bob,

Just want to confirm that "match input-interface" will only work for
incoming traffic correct? (I tried with a 3 router setup with ICMP and
this seems to be the case)

thanks

Mike,

If you reference the physical interface in the class-map command "match
input-interface", then it will match traffic on all subinterfaces.

Hope that helps,

If you have multiple sub interfaces and you want to match all traffic
from
them, do you specify all sub interfaces in the class-map or just the
physical interface to capture all traffic on the subs?
