Description (partial)

Even though Qos policy with policers are applied on Qos targets
such as port and vlan in input and/or output direction, traffic on certain
vlans does not get policed correctly.  However, any unconditional marking
does get applied correctly.

Assume QoS policy Q is configured to police certain class of traffic
to 5MB.  There are 2 configurations causing the problem:
(assume P=port, V=vlan and PV=vlan-port.
1.  When Q is applied on P and Q1 applied on V and no Qos policy on PV.
 2. When Q is applied on P, and no Qos policy on PV,
     V is configured as an SVI  and multicast pim is configured on SVI.
     Qos may or may not be configured on V.
3. Same config as 2, but no policy on P and PV but Q applied on V.

In both the above configuration, vlan traffic on port P and traffic from
all other vlans on that port are independently policed to 5MB.
But according to Qos config the expectation is that
all traffic on P irrespective of vlan should be policed to 5MB.
