Q-in-Q Folder
This function allows the user to enable or disable the Q-in-Q function. Q-in-Q is designed for service
providers to carry traffic from multiple users across a network.
Q-in-Q is used to maintain customer specific VLAN and Layer 2 protocol configurations even when the
same VLAN ID is being used by different customers. This is achieved by inserting SPVLAN tags into
the customer’s frames when they enter the service provider’s network, and then removing the tags
when the frames leave the network.
Customers of a service provider may have different or specific requirements regarding their internal
VLAN IDs and the number of VLANs that can be supported. Therefore customers in the same service
provider network may have VLAN ranges that overlap, which might cause traffic to become mixed up.
So assigning a unique range of VLAN IDs to each customer might cause restrictions on some of their
configurations requiring intense processing of VLAN mapping tables which may exceed the VLAN
mapping limit. Q-in-Q uses a single service provider VLAN (SPVLAN) for customers who have
multiple VLANs. Customer’s VLAN IDs are segregated within the service provider’s network even
when they use the same customer specific VLAN ID. Q-in-Q expands the VLAN space available while
preserving the customer’s original tagged packets and adding SPVLAN tags to each new frame.
Parameter Description
VID List (e.g.: 2-5) Enter a VLAN ID List that can be added, deleted or configured.
Advertisement Enabling this function will allow the Switch to send out GVRP packets to
outside sources, notifying that they may join the existing VLAN.
Port List (e.g.: 1-5) Allows an individual port list to be added or deleted as a member of the
VLAN.
Tagged Specifies the port as 802.1Q tagged. Checking the box will designate the port
as Tagged.
Untagged Specifies the port as 802.1Q untagged. Checking the box will designate the
port as untagged.
Forbidden Select this to specify the port as not being a member of the VLAN and that
the port is forbidden from becoming a member of the VLAN dynamically.
