Port-Based
Priority
Classification
R/W
=00, Ingress packets on port 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 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 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 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.
00
2
Tag Insertion
R/W
=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
Note: For the tag insertion available, the register 194 bits [5-0] have to be set
first.
0
1
Tag Removal
R/W
=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
TXQ Split Enable
R/W
=1, Split TXQ to 4 queue configuration. It cannot be enable at the same time
with split 2 queue at register 18, 34,50 bit 7.
=0, No split, treated as 1 queue configuration
0
