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

Description
Default
7
Broadcast Storm
Protection Enable
R/W
1 = Enable broadcast storm protection for ingress packets on
port
0 = Disable broadcast storm protection
0
6
DiffServ Priority
Classification Enable
R/W
1 = Enable DiffServ priority classification for ingress packets
(IPv4 and IPv6) on port
0 = Disable DiffServ function
0
5
802.1p Priority
Classification Enable
R/W
1 = Enable 802.1p priority classification for ingress packets on
port
0 = Disable 802.1p
0
4-3
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
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
TX Multiple Queues
Select Enable
R/W
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.
