Advanced Configuration
: Before setting the Management VLAN Id, make sure that the station that manages the device is a member of the
same VLAN; else, your access to the device will be lost.
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.
:
• 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/Double VLAN based on the management VLAN ID
configured.
• Only SU, End Point A and End Point B support Double VLAN (Q in Q) feature.
5. Service VLAN TPID: The Tag Protocol Identifier (TPID) helps to identify the frame as VLAN tagged frame. By default
the Service VLAN TPID is set to 0x8100. To interwork with few vendor devices that set the TPID to 0x9100, the device
allows the user to configure Service VLAN TPID as 0x9100. In this case, when a QinQ packet goes out of the device,
the Ether type of outer VLAN tag is changed to 0x9100.
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.
: When Double VLAN is enabled on the device, the Service VLAN ID should not be set to -1.
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.
5.8.2 Ethernet VLAN Configuration
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
5.8.2.1 Transparent 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:
