Ingress VLAN Filtering
1 = the switch discards packets whose VID port membership in VLAN table bits [18:16] does
not include the ingress port.
0 = no ingress VLAN filtering.
13
0
RW
Discard Non PVID Packets
1 = the switch discards packets whose VID does not match the ingress port default VID.
0 = no packets are discarded.

Transmit Enable
1 = enable packet transmission on the port.
0 = disable packet transmission on the port.

Receive Enable
1 = enable packet reception on the port.
0 = disable packet reception on the port.

Learning Disable
1 = disable switch address learning capability.
0 = enable switch address learning.
7

Sniffer Port
1 = port is designated as the sniffer port and transmits packets that are monitored.
0 = port is a normal port.
6
0
RW
Receive Sniff
1 = all packets received on the port are marked as “monitored packets” and forwarded to the
designated “sniffer port”.
0 = no receive monitoring.
5
0
RW
Transmit Sniff
1 = all packets transmitted on the port are marked as “monitored packets” and forwarded to
the designated “sniffer port”.
0 = no transmit monitoring.

User Priority Ceiling
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.”
2-0

RW
Port VLAN Membership
Define the port’s Port VLAN membership. Bit 2 stands for host port, bit 1 for port 2, and bit 0
for port 1. The port can only communicate within the membership. A ‘1’ includes a port in the
membership; a ‘0’ excludes a port from the membership.
