Port Default VID and Priority
When the port VID table is selected (PVIDnVLAN=1 of the
VLAN Command Register
the default VID for the port and bits 14:12 specify the default priority. All
other bits of this field are reserved. These bits are used when a packet is
received without a VLAN tag or with a NULL VLAN ID. By default, the VID
and priority for all three ports is 0.
VLAN Data
When the VLAN table is selected (PVIDnVLAN=0 of the
VLAN Command Register
table entry as follows:
Switch Engine VLAN Read Data Register (SWE_VLAN_RD_DATA)
This register is used to read the VLAN or Port VID tables.

Register #:
Member Port 2
Indicates the configuration of Port 2 for this VLAN entry.
1 = Member - Packets with a VID that matches this entry
are allowed on ingress. The port is a member of the
broadcast domain on egress.
0 = Not a Member - Packets with a VID that matches this
entry are filtered on ingress unless the Admit Non Member
bit in the
(SWE_ADMT_N_MEMBER)
not a member of the broadcast domain on egress.
Un-Tag Port 2
When this bit is set, packets received on Port 2 with a VID
that matches this entry will have their tag removed when re-
transmitted by egress ports that are designated as Hybrid
ports via the
(BM_EGRSS_PORT_TYPE).
Member Port 1
See description for Member Port 2.
Un-Tag Port 1
See description for Un-Tag Port 2.
Member Port 0 (Host MAC)
