Your options are as follows:
•
View , without changing, the behavior attributes assigned to each port under the
selected VLAN ID: ACT=NONE (default).
•
Edit the behavior attributes assigned to each port under the selected VLAN ID.
Once the VLAN ID targeted for editing is selected, use the
◄ ►
arrow keys to
select the ACT parameter, and then use the
▲ ▼ arrow keys to select
ACT=Edit.
2. Change the behavior attribute of a specific port as needed.
Use the
◄ ►
arrow keys to select P1 , P2 , P3 , or P4 . Then, use the
▲▼ arrow keys to
designate the attribute for that 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”
– if this is done, and you Presses 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 ENTER to save those
changes. ENTER must be pressed to save the change. CLEAR will discard the change.
You must take into consideration, when editing VLAN table entries, the following rules:
•
The modem cannot filter VLAN 1.
•
All Untagged / Tagged packets arriving at the LAN port are tagged (four byte VLAN
“frame” is added) with the configured VLAN ID .
•
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.
•
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.
•
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.
•
Delete the selected VLAN ID . After targeting a VLAN ID for deletion, use the
◄ ►
arrow
keys to select the ACT parameter, and then use the
▲▼ arrow keys to select
ACT=Del.
Press ENTER to execute deletion of the selected VLAN ID.
You must take into consideration that, when deleting VLAN IDs, an entry
associated with an enabled PVID cannot be deleted.
