Description
reserved
Ingress VLAN filtering
1 = the switch will discard packets whose VID port membership in VLAN
table bits [18:16] does not include the ingress port.
0 = no ingress VLAN filtering.
Discard Non PVID packets
1 = the switch will discard packets whose VID does not match ingress port
default VID.
0 = no packets will be discarded.
Reserved.
For factory testing purpose only. Always write 0.
Reserved
Must be 0
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 sniffer port and will transmit packets that are
monitored.
0 = Port is a normal port
Receive sniff
1 = All the packets received on the port will be marked as “monitored
packets” and forwarded to the designated “sniffer port”
0 = no receive monitoring
Transmit sniff
1 = All the packets transmitted on the port will be marked as “monitored
packets” and forwarded to the designated “sniffer port”
0 = no transmit monitoring
Reserved
User Priority Field
1 = if the packet’s “user priority field” is greater than the “user priority bits”
in host’s VID Control register bits [15:13], replace the packet’s “user
priority field” with the “user priority bits” in host’s VID Control register bits
[15:13].
0 = do not compare and replace the packet’s ‘user priority field”
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. An ‘1’ includes a port in the membership; an ‘0’ excludes a
port from the membership.
