Priority-Tagged Frames on the Default VLAN

Priority-tagged frames are 802.1Q tagged frames with VLAN ID 0. For VLAN classification, these
packets are treated as untagged. However, the dot1p value is still honored when you configure
or
dynamic dot1p trust dot1p
When priority-tagged frames ingress an untagged port or hybrid port the frames are classified to the default
VLAN of the port, and to a queue according to their dot1p priority if you configure
or . When priority-tagged frames ingress a tagged port, the frames are dropped because for a
dotp trust dot1p
tagged port the default VLAN is 0.
FTOS Behavior: Hybrid ports can receive untagged, tagged, and priority tagged frames. The rate
metering calculation may be inaccurate for untagged ports because an internal assumption is made
that all frames are treated as tagged. Internally, the ASIC adds a 4-bytes tag to received untagged
frames. Though these 4-bytes are not part of the untagged frame received on the wire, they are
included in the rate metering calculation resulting in metering inaccuracy.

Configure Port-based Rate Policing

To configure rate policing ingress traffic on an interface, use the
mode (Figure 24-4). If the interface is a member of a VLAN, you may specify the VLAN for which ingress
packets are policed.
