Description
Default: Edge
This parameter specifies how the port determines its membership
in VLANs. There are few types of ports:
• Edge - the port is only a member of one VLAN (its native VLAN
specified by the PVID parameter).
• Trunk - the port is automatically a member of all configured
VLANs. Frames transmitted out of the port on all VLANs except
the port's native VLAN will be always tagged. It can also be
configured to use GVRP for automatic VLAN configuration.
• PVLANEdge - the port is only a member of one VLAN (its native
VLAN specified by the PVID parameter), and does not forward
traffic to other PVLANedge ports within the same VLAN.
• QinQ - the port is a trunk port using double-VLAN tagging, or
nested VLANs. An extra VLAN tag is always added to all frames
egressing this port. VID in the added extra tag is the PVID of the
frame's ingress port. VLAN tag is always stripped from frames
ingressing this port.
NOTE
Depending on the hardware installed, some
switch models allow only one switch port be
configured to QinQ mode at a time.
Synopsis: 1 to 4094
Default: 1
The Port VLAN Identifier specifies the VLAN ID associated with
untagged (and 802.1p priority tagged) frames received on this
port.
Frames tagged with a non-zero VLAN ID will always be associated
with the VLAN ID retrieved from the frame tag.
Modify this parameter with care! By default, the switch is
programmed to use VLAN 1 for management and every port on
the switch is programmed to use VLAN 1. If you modify a switch
port to use a VLAN other than the management VLAN, devices on
that port will not be able to manage the switch.
Synopsis: { Untagged, Tagged }
Default: Untagged
Specifies whether frames transmitted out of the port on its
native VLAN (specified by the PVID parameter) will be tagged or
untagged.
NOTE
When QinQ is enabled, all non-QinQ ports will be
untagged and cannot be changed, and all QinQ
ports will be tagged, and cannot be changed.
Synopsis: { Adv&Learn, Adv Only, Disabled }
Default: Disabled
Configures GVRP (Generic VLAN Registration Protocol) operation
on the port. There are several GVRP operation modes:
• DISABLED - the port is not capable of any GVRP processing.
• ADVERTISE ONLY - the port will declare all VLANs existing in the
switch (configured or learned) but will not learn any VLANs.
• ADVERTISE & LEARN - the port will declare all VLANs existing in
the switch (configured or learned) and can dynamically learn
VLANs.
Only Trunk ports are GVRP-capable.
