port as
Tagged
or
Filtered
for a Trunk port, or
Untagged
or
Filtered
for an Access port.
The “Untagged” option is available only when Port Mode has been set to Access
for the selected port.
You may not designate the behavior attributes for all four ports as “Filtered” –
is this is done, and you
Press
es ENTER to save this configuration change, an
error message will display as follows:
ERROR: Entry with FILTERED on all ports
is not allowed.
Once the port attributes have been changed (with
ACT=Edit
active), press

You must take into consideration, when editing VLAN table entries, the following rules:
o
The modem cannot filter VLAN 1.
o
All
Untagged
/
Tagged
packets arriving at the LAN port are tagged (four byte
VLAN
“frame” is added) with the configured
VLAN ID
.
o
If the port is in
Port Mode
, any packet arriving from the WAN that matches this
PVID
will have the
VLAN
tag removed and passed out the Ethernet.
o
If the port is in
Port Mode
and the packet does not match the
PVID
, the
VLAN
table
must be checked to determine if the packet should pass. Packets leaving a port in Port
Mode are always untagged.
o
If the port behavior Port Mode attribute is set to Trunk, then the
VLAN
table is
referenced to determine if the packet should pass. In this mode, packets will either be
filtered (dropped) or passed “as is” with the VLAN header intact.
