Priority-tagged Frames on the Default VLAN
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
is configured.

FTOS Behavior: Hybrid ports can receive untagged, tagged, and priority tagged frames. The rate metering
calculation might be inaccurate for untagged ports, since 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.
