The system supports the 802.1 QinQ standard, which defines the way to have 2 VLAN tags (double-tagged frames). This procedure allows an additional VLAN tag, called Metro VLAN tag, to be inserted into an existing IEEE 802.1Q tagged frame. This is a solution to transport multiple customers' VLANs across the service provider's network without interfering with each other. The expanded VLAN space allows the service provider to provide certain services, such as Internet access, on specific VLANs for specific customers, and yet provide other types of services for other customers on other VLANs.

The Q in Q page comprises the following components:
Ethertype: The EtherType to be used with the Metro tags. The available options are 8100, 9100 and 9200.
Metro Tags Table: Enables adding, deleting and editing the properties of up to four Metro Tags. The table includes the following properties for each entry:
Parameter |
Description |
ID |
An auto- sequential number from 1 to 4 for a modular Base Station, or from 1 to 2 for a Micro Base Station. |
Metro Tag |
TheMetro Tag to be added to packets with a VLAN ID within the range specified by Start VLAN and End VLAN parameters of the entry. The range is from 0 to 4094. |
Start VLAN |
The lower limit of the range defining the VLAN IDs associated the applicable Metro Tag. The range is from 0 to 4094. |
End VLAN |
The upper limit of the range defining the VLAN IDs associated the applicable Metro Tag.The range is from 0 to 4094. End VLAN cannot be lower than Start VLAN. |

NOTE |
VLAN ranges defined for different Metro Tags cannot overlap. |
