Apply QOS to vrf traffic?(Ethernet SubInts)

Question

Hi,
I'm trying to apply "GOLD" QOS to vrf traffic that is terminated on eth subints, but class-map is not allowing me to match on subinterfaces:
class-map match-any GOLD
match mpls experimental topmost 5
match ip precedence 5
match input-interface fastEthernet 0/0 (Subints not allowed)
I also cannot match on access-group, as the traffic is within a vrf.
Should I be creating a seperate policy-map marking the traffic as GOLD, and then apply this as a "service-policy input" to each eth subint the vrf is associated with?

Hi,
when you apply the service-policy to an interface you do NOT need to specify the interface in the class-map! Example:
class-map match-any VoIP
match ip precedence 5
match ip dscp ef
policy-map Marking
class VoIP
set mpls experimental imposition 5
interface FastEthernet0/0.100
ip address ...
encapsulation dot1q 100
service-policy input Marking
This will set MPLS exp bits on all traffic coming into F0/0.100 and being marked with either Prec 5 or DSCP EF.
Sidenote: using an ACL in class VoIP will also only match traffic on the interface, where the policy is applied. So overlapping customer addresses are not an issue.
Hope this helps! Please rate all posts.
