Description
Port 2 port-based VLAN mask bits – Use to select which
ports may transmit packets received on port 2.
PV21 = 1, port 1 may transmit packets received on port 2
PV21 = 0, port 1 will not transmit any packets received on
port 2
PV23 = 1, port 3 may transmit packets received on port 2
PV23 = 0, port 3 will not transmit any packets received on
port 2
Digital ground
3.3V digital V
Port 1 port-based VLAN mask bits – Use to select which
ports may transmit packets received on port 1.
PV12 = 1, port 2 may transmit packets received on port 1
PV12 = 0, port 2 will not transmit any packets received on
port 1
PV13 = 1, port 3 may transmit packets received on port 1
PV13 = 0, port 3 will not transmit any packets received on
port 1
Enable 802.1p priority classification on port 3 ingress
1 = enable
0 = disable
Enable is from the receive perspective. If 802.1p processing
is disabled or there is no tag, priority is determined by the
P3_PP pin.
Enable 802.1p priority classification on port 2 ingress
1 = enable
0 = disable
Enable is from the receive perspective. If 802.1p processing
is disabled or there is no tag, priority is determined by the
P2_PP pin.
Enable 802.1p priority classification on port 1 ingress
1 = enable
0 = disable
Enable is from the receive perspective. If 802.1p processing
is disabled or there is no tag, priority is determined by the
P1_PP pin.
Select transmit queue split on port 3
1 = split
0 = no split
The split sets up high and low priority queues. Packet priority
classification is done on ingress ports, via port-based, 802.1p
or TOS based scheme. The priority enabled queuing on port 3
is set by P3_TXQ2.
