Configuring VLAN Interfaces
You can configure VLAN behavior for specific interfaces, including the
default VLAN identifier (PVID) and accepted frame types. The 802.1Q
Per Port Configuration page allows you to change the VLAN parameters
for individual ports. Each row of the table corresponds to one port or
static trunk; trunked ports cannot be configured individually. Also, note
that the VLAN attributes of dynamically configured LACP trunks cannot
be modified.
Field Attributes
Port/Trunk – The port-number of the port or the ID of a trunk.
VLAN Aware Enabled – VLAN aware ports are able to use VLAN
tagged frames to determine the destination VLAN of a frame. (Default:
Enabled)
VLAN aware ports will strip the VLAN tag from received frames and
insert the tag in transmitted frames (except for the PVID). VLAN
unaware ports will not strip the tag from received frames or insert the tag
in transmitted frames.
For QinQ operation, a customer port should be set to VLAN unaware
and a provider port (trunk port) should be set to VLAN aware.
Ingress Filtering Enabled – If enabled, incoming frames for VLANs
which do not include this ingress port in their member set will be
discarded. (Default: Disabled)
QinQ – A QinQ enabled port will accept packets up to 1526 bytes in
length, which means double tag header frames can be accepted. QinQ
should be enabled for provider ports but not for customer ports.
QinQ “customer” ports are those ports that are connected to normal
VLAN aware switches in the customer’s network. QinQ “network”
ports are those which are connected to the service provider's network.
To tunnel packets through a service provider’s metro network, QinQ
needs to be enabled on the network port.
Packet Type – Sets the interface to accept all frame types, including
tagged or untagged frames, or only tagged frames. (Default: All)
If the Packet Type is set to “All,” the port can accept incoming tagged
