The following issues must be taken into consideration when editing VLAN IDs:
• The NATIVE VLAN cannot be deleted from the table and the attribute cannot be edited.
• All untagged/tagged packets arriving at the LAN port will be tagged (four byte VLAN “frame”
will be added) with the configured VLAN ID.
• If the port is in NATIVE mode, any packet arriving from the WAN that matches
this VLAN ID, will have the VLAN tag removed and passed out the Ethernet.
• If the port is in NATIVE mode and the packet does not match the PVID, the VLAN
table must be checked to determine if the packet should pass.
• If the port is set to TAGGED mode, then the VLAN table is referenced to determine
if the packet should pass.
