Figure 5-86 System-Level VLAN Configuration (SU/End Point A/End Point B)
1. VLAN Status: This parameter is used to either enable or disable VLAN feature on the device. By default, this
parameter is disabled. To enable VLAN, select the VLAN Status box. If VLAN status is enabled, it indicates that locally
configured VLAN parameters will be applied on the device. If VLAN status is disabled, it indicates that the device is
open for remote VLAN configuration.
2. Management VLAN Id: This parameter enables the user to configure VLAN Id for management frames (SNMP, ICMP,
Telnet and TFTP). The stations that manage the device must tag the management frames with the management VLAN
Id. By default, the Management VLAN Id is set to -1 which indicates no tag is added to the management frame. To set
VLAN tag to the management frame, enter a value ranging from 1 to 4094.
: 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.
:
·
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.

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.
