Hi Ghassan.

Thanks for the info.

Is this regardless of Supervisor engine?
Did they mention if this is considered a bug? if yes, did they gave you the bug id?

Some are saying "mls-qos vlan-based" has to be configured for it to work.

Not sure if this is true, im still searching...

I faced the same issue with 7613 on interface vlan ingress policing.
After a lot of trials I opened a TAC case and yes it was not supported on interface vlan ingress direction.
The only solution proposed was to apply aggregate policing on the L2 trunks (i.e. All the vlans) which was inconvenient to me.
