Broadcast Storm Protection Enable
1 = enable broadcast storm protection for ingress packets on the port.
0 = disable broadcast storm protection.

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

802.1p Priority Classification Enable
1= enable 802.1p priority classification for ingress packets on the port.
0 = disable 802.1p.

0x0
RW
Port-Based Priority Classification
00 - ingress packets on port are classified as priority 0 queue if “DiffServ” or “802.1p”
classification is not enabled or fails to classify.
01 - ingress packets on port are classified as priority 1 queue if “DiffServ” or “802.1p”
classification is not enabled or fails to classify.
10 - ingress packets on port are classified as priority 2 queue if “DiffServ” or “802.1p”
classification is not enabled or fails to classify.
11 - ingress packets on port are classified as priority 3 queue 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.

0
RW
Tag Insertion
1 = when packets are output on the port, the switch adds 802.1p/q tags to packets
without 802.1p/q 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.
1
0
RW
Tag Removal
1 = when packets are output on the port, the switch removes 802.1p/q tags from packets
with 802.1p/q tags when received. The switch will not modify packets received without
tags.
0 = disable tag removal.
0
RW
TX Multiple Queues Select Enable
1 = the port output queue is split into four priority queues.
0 = single output queue on the port. There is no priority differentiation even though
packets are classified into high or low priority.
