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 port
0 = disable diffserv function

RW
Port based priority classification
00 = ingress packets on port 1 will be classified as priority 0 queue if
“Diffserv” or “802.1p” classification is not enabled or fails to classify.
01 = ingress packets on port 1 will be classified as priority 1 queue if
“Diffserv” or “802.1p” classification is not enabled or fails to classify.
10 = ingress packets on port 1 will be classified as priority 2 queue if
“Diffserv” or “802.1p” classification is not enabled or fails to classify.
11 = ingress packets on port 1 will be 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 will add 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 will remove 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 fourpriority queues.
0 = single output queue on the port. There is no priority differentiation
even though packets are classified into high or low priority.
