PV12
Ipu
109
PV13
Ipu
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.
110
P3_1PEN
Ipd
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.
111
P2_1PEN
Ipd
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.
112
P1_1PEN
Ipd
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.
113
P3_TXQ2
Ipd
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.
114
P2_TXQ2
Ipd
Select transmit queue split on port 2
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 2 is set by P2_TXQ2.
115
P1_TXQ2
Ipd
Select transmit queue split on port 1
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 1 is set by P1_TXQ2.
116
P3_PP
Ipd
Select port-based priority on port 3 ingress
1 = high
0 = low
<default>
802.1p and Diffserv, if applicable, will take precedence.
