DiffServ Priority Classification
Enable
1, enable DiffServ priority classification for ingress packets on
port.
0, disable DiffServ function.

Port-Based Priority Classification
Enable
1, ingress packets on the port will be classified as high
priority if “DiffServ” or “802.1p” classification is not enabled or
fails to classify.
0, ingress packets on port will be classified as low priority if
“DiffServ” or “802.1p” classification is not enabled or fails to
classify.
Note: “DiffServ”, “802.1p” and port priority can be enabled at
the same time. The OR’ed result of 802.1p and DSCP
overwrites the port priority.

Tag insertion
1, when packets are output on the port, the switch will add
802.1q tags to packets without 802.1q tags when received.
The switch will not add tags to packets already tagged. The
tag inserted is the ingress port’s “port VID.”
0, disable tag insertion.
R/W
0
1
Tag Removal
1, when packets are output on the port, the switch will
remove 802.1q tags from packets with 802.1q tags when
received. The switch will not modify packets received without
tags.
0, disable tag removal.
R/W
0
Priority Enable
1, the port output queue is split into high and low priority
queues.
0, single output queue on the port. There is no priority
differentiation even though packets are classified into high or
low priority.
