You must follow these rules when creating or adding a VLAN table entry:
•
The VLAN ID (0001-4095) must be unique – it cannot be a duplicate of any previously
assigned VLAN ID, including PVIDs in the VLAN ID table.
• If a port is not in Trunk Mode (PortMode = Trunk), the behavior attribute for each port may
be set as Tagged or Filtered.
For any VLAN ID (Trunk Mode) created, at a minimum, one port must be
defined as ‘Tagged’.
You must follow these rules when assigning PVIDs:
• The PVID (0001-4095) must be unique – it cannot be a duplicate of any previously assigned
VLAN ID, including PVID. The only exception to this rule is that the default value 0001 may
be assigned as the PVID for all ports.
•
If a port is in Access Mode (Port Mode = Access), the behavior attribute for each port may
be set as Untagged or Filtered.
•
PVIDs are automatically ENTER ed into the VLAN ID Table when changed.
• When a new PVID entry is added to the VLAN ID Table, the “other” ports will default to
Filtered .
•
When a PVID is changed, the entry in the VLAN ID Table for that port will change to
Filtered
.
If the rest of the ports are also Filtered , then
delete
that entry. If any other port has been
marked Tagged , leave the entry in the table.
