The following table describes the fields in this screen.

VDSL Port Setup: VLAN Setup
LABEL DESCRIPTION
UP Click this to return to the previous screen.
PVID / Priority PVID refers to the customer’s VLAN ID. In the first field, enter the VLAN ID (from 1 to
4094) to use for untagged frames received on this port.
In the second field, enter the priority level for the customer VLAN ID. "0" is the lowest
priority level and "7" is the highest.
TLS Enable Transparent LAN Service (also known as VLAN stacking or Q-in-Q) allows a service
provider to distinguish multiple customers VLANs, even those with the same (customer-
assigned) VLAN ID, within its network.
Once you enable TLS, all packets will be added an extra “VLAN tag” (SPVID/SPriority) and
forwarded toward Gigabit Ethernet interface(s).
Select this option to enable TLS (Transparent LAN Service). Clear this check box to disable
this feature. Refer to
Section 9.2.12 on page 209 for more information.
TLS SVID /
SPriority This is the service provider’s VLAN ID (the outer VLAN tag). In the first field, enter the
service provider ID (from 1 to 4094) for frames received on this port.
In the second field, enter the priority level for the service provider’s VLAN ID. "0" is the
lowest priority level and "7" is the highest.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The
system loses these changes if it is turned off or loses power, so use the Config Save link
on the navigation panel and then the Save button to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring the screen again.
DT SVID When using double-tagging, this is the service provider’s VLAN ID (the outer VLAN tag)
that the line card assigns to untagged frames received on this port. Refer to
Section
9.2.14 on page 211 for more information.
SPriority This field displays the IEEE 802.1p priority level for the service provider tag that the line
card adds to untagged frames that come in on this port. "0" is the lowest priority level
and "7" is the highest.
DT Enable Select this to turn on double-tagging for this port.
DT CVID When using double-tagging, this is the customer VLAN ID (the inner VLAN tag) that the
line card assigns to untagged frames received on this port.
CPriority This field displays the IEEE 802.1p priority level for the customer tag that the line card
adds to untagged frames that come in on this port. "0" is the lowest priority level and "7"
is the highest.
Apply Click Apply to save the changes in this screen to the system’s volatile memory. The
system loses these changes if it is turned off or loses power, so use the Config Save link
on the navigation panel and then the Save button to save your changes to the non-
volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring the screen again.
VID Type a VID (VLAN ID) to add this port as a member.
This must be the VLAN ID of a VLAN that is already configured. The port that you are
configuring must also be set to the fixed status in the VLAN.
Registration Select join to have the port be a member of the specified VLAN.
Select leave to remove the port from the specified VLAN.
Tag Select the check box to tag all frames transmitted on this port with the port’s VID.
