Description
Reserved
Ingress VLAN Filtering
1= the switch discards packets whose VID port membership in VLAN table bits [18:16]
does not include the ingress port VID.
0 = no ingress VLAN filtering.
Discard Non PVID Packets
1 = the switch discards packets whose VID does not match the ingress port default
VID.
0 = no packets are discarded.
Force Flow Control
1 = always enable flow control on the port, regardless of AN result.
0 = the flow control is enabled based on AN result.
Back Pressure Enable
1 = enable port’s half-duplex back pressure.
0 = disable port’s half-duplex back pressure.
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.
Sniffer Port
1 = port is designated as a sniffer port and transmits packets that are monitored.
0 = port is a normal port.
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.
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.
Reserved
User Priority Ceiling
1 = if the packet’s “priority field” is greater than the “user priority field” in the port VID
control register bit[15:13], replace the packet’s “priority field” with the “user priority
field” in the port VID control register bit[15:13].
0 = do no compare and replace the packet’s “priority field.”
Port VLAN Membership
Define the port’s Port VLAN membership. Bit 2 stands for the 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.
