Register Name:
Register Description:
Register Address:
086h:
Default
Whenever a read operation is performed on this configuration register, the data stored in the VLAN Table at the
address specified by the SU.VTAA register is read. The VTAA value must be initialized prior to the read operation.
VLAN Forwarding. These values determine whether to forward a frame to an extract or forwarding queue or (in
the LAN to WAN direction) whether to discard the frame, There are 4096 VLAN IDs. The user may configure any
number of these 4096 VLAN IDs. The data in this register provides the read data that was retrieved from a VLAN
Table Read operation.
Bit 5: WAN-VLAN Extract Forwarding (WAN-VLAN Trap) (WVEFR)
Bit 4: WAN-VLAN Queue Forwarding (WVQFR; Only valid in Forwarding Mode 5)
Bit 3: LAN-VLAN Discard (LVDR)
Bit 2: LAN-VLAN Extract Forwarding (LAN-VLAN Trap) (LVEFR)
Bits 0-1: LAN-VLAN Queue Forwarding (LVQFR[2:1])
NOTE:
Rev: 063008
087h:
Default
LAN Extract forwarding takes precedence over LAN Queue forwarding.
LAN Discard takes precedence over LAN Extract forwarding (trapping).
WAN Extract forwarding (trapping) takes precedence over WAN Queue forwarding.

0 = Do nothing.
1 = Trap frames received from the WAN with this VID and place them in the WAN Extract Queue.
0 = Forward frames received from the WAN with this VID value to Ethernet Port 1
1 = Forward frames received from the WAN with this VID value to Ethernet Port 2
0 = Do nothing.
1 = Discard frames received from the LAN with this VID
0 = Do not forward this frame to the LAN Extract Queue
1 = Forward this frame to the LAN Extract Queue
00 = Forward frames with a VID value equal to this table address to LAN Queue Group 1
01 = Forward frames with a VID value equal to this table address to LAN Queue Group 2
10 = Forward frames with a VID value equal to this table address to LAN Queue Group 3
11 = Forward frames with a VID value equal to this table address to LAN Queue Group 4
