3. Management VLAN Priority: This parameter is used to set IEEE 802.1p priority for the management frames. By

default, the priority is set to 0. To set the VLAN priority, enter a value ranging from 0 to 7.

4. Double VLAN (Q in Q) Status: Q in Q (also called as Double VLAN or Stacked VLAN) mechanism expands the VLAN

space by tagging the tagged packets, thus producing a “double-tagged” frame. The expanded VLAN space allows the
service provider to provide certain services, such as Internet access on specific VLANs for specific customers, and still
allows the service provider to provide other types of services for their other customers on other VLANs.

By default, Double VLAN is disabled on the device. To enable, select Enable from the Double VLAN (Q in Q) Status 
box and click OK.

•

Only SU, End Point A and End Point B support Double VLAN (Q in Q) feature.

•

If Double VLAN (Q in Q) Status is enabled, device expects Double VLAN tagged packet in Downlink direction. 
Management can be accessed with single VLAN based on the management VLAN ID configured.

For more details on QinQ, refer to Appendix 

. 

5. Service VLAN TPID: The Tag Protocol Identifier (TPID) helps to identify the frame as VLAN tagged frame. The user can

configure Service VLAN TPID as either 0x8100, 0x9100, or 0x88a8. By default the Service VLAN TPID is set to 0x8100.

6. Service VLAN Id: This parameter enables the user to configure outer/service provider VLAN ID for the data frames. By

default, the Service VLAN ID is set to -1 which indicates no outer/service VLAN tag is added to the data frame. To set
VLAN tag to the frame, enter a value ranging from 1 to 4094.

7. Service VLAN Priority: This parameter is used to set IEEE 802.1p priority in outer/service VLAN tag for the data

frames. By default, the priority is set to 0. To set the VLAN priority, enter a value ranging from 0 to 7.

You can configure VLAN on the Ethernet interface(s) by using any one of the following VLAN Modes:

1. Transparent Mode

2. Access Mode

3. Trunk Mode

Transparent mode can be configured in a BSU, SU and End Point devices. This mode is equivalent to NO VLAN support and is
the default mode. It is used to connect VLAN aware or unaware networks. In this mode, the device transfers both tagged and
untagged frames received on the Ethernet or WORP interface. 

To configure the Ethernet interface of the device in VLAN Transparent Mode, navigate to ADVANCED CONFIGURATION >
VLAN > Ethernet. The VLAN Ethernet Configuration screen appears:
