Tag Removal
1 = when packets are output on the port, the switch removes 802.1p/q tags from packets with
802.1p/q tags when received. The switch will not modify packets received without tags.
0 = disable tag removal.
0
RW
TX Multiple Queues Select Enable
1 = the port output queue is split into four priority queues.
0 = single output queue on the port. There is no priority differentiation even though packets are
classified into high or low priority.
Bank 48 Port 1 Control Register 2 (0x02): P1CR2
This register contains the global per port control for the switch function.

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.

RW
Discard Non PVID Packets
1 = the switch discards packets whose VID does not match the ingress port default VID.
0 = no packets are discarded.

RW
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.

RW
Back Pressure Enable
1 = enable port’s half-duplex back pressure.
0 = disable port’s half-duplex back pressure.

Learning Disable
1 = disable switch address learning capability.
0 = enable switch address learning.

0
RW
Sniffer Port
1 = port is designated as a sniffer port and transmits packets that are monitored.
0 = port is a normal port.
6
0
RW
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.

0
RW
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.
