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, takes precedence.
117
P2_PP
Ipd
Select port-based priority on port 2 ingress
1 = high
0 = low
<default>
802.1p and DiffServ, if applicable, takes precedence.
118
P1_PP
Ipd
Select port-based priority on port 1 ingress
1 = high
0 = low
<default>
802.1p and DiffServ, if applicable, takes precedence.
119
P3_TAGINS
Ipd
Enable tag insertion on port 3 egress
1 = enable
0 = disable
All packets transmitted from port 3 will have 802.1Q tag.
Packets received with tag will be sent out intact. Packets
received without tag will be tagged with ingress port’s default
tag.
120
P2_TAGINS
Ipd
Enable tag insertion on port 2 egress
1 = enable
0 = disable
All packets transmitted from port 2 will have 802.1Q tag.
Packets received with tag will be sent out intact. Packets
received without tag will be tagged with ingress port’s default
tag.
Note:
1. Ipd = Input w/ internal pull-down.
