Port Registers
The following registers are used to enable features that are assigned on a per port basis. The register bit
assignments are the same for all ports, but the address for each port is different, as indicated.
Register 16 (0x10): Port 1 Control 0
Register 32 (0x20): Port 2 Control 0
Register 48 (0x30): Port 3 Control 0
Register 64 (0x40): Port 4 Control 0
Register 80 (0x50): Port 5 Control 0

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.
R/W

802.1p Priority
Classification Enable
1, enable 802.1p priority classification for ingress
packets on port.
0, disable 802.1p.
R/W

4–3
Port-Based Priority
Classification Enable
= 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.
R/W

2
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.
