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

R/W
= 1, enable broadcast storm protection for ingress packets on the
port
= 0, disable broadcast storm protection

R/W
= 1, enable diffserv priority classification for ingress packets on
port
= 0, disable diffserv function

R/W
= 1, enable 802.1p priority classification for ingress packets on
port

P2_1PEN (port 2),
P3_1PEN (port 3)

Port based
priority
classification
enable
R/W
= 1, ingress packets on the port will be classified as high priority
if
“Diffserv” or “802.1p” classification is not enabled or fails to
classify.
= 0, ingress packets on port will be classified as low priority 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.
Pin value
during reset:
P1_PP (port 1),
P2_PP (port 2),
P3_PP (port 3)
3
User Priority
Ceiling
R/W
= 1, if the packet’s “user priority field” is greater than the “user
priority field” in the port default tag register, replace the
packet’s “user priority field” with the “user priority field” in the
port default tag register.
= 0, do no compare and replace the packet’s ‘user priority field”
0
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
Pin value
during reset:
P1_TAGINS (port 1),
P2_TAGINS (port 2),
P3_TAGINS (port 3)
