DTPVCs (Double-Tag Permanent Virtual Circuits) add double VLAN tags to untagged frames received
from an ADSL, SHDSL, or VDSL2 (operating in ADSL2+ connection mode) port on the specified
PVC. These double VLAN tags consist of an inner c-tag (customer tag) and an outer s-tag (service
provider tag).
Double-tagged VLAN can be used for applications such as distinguishing between multiple service
providers or distinguishing multiple customers VLANs, even those with the same customer VLAN ID.
The service provider can manage up to 4,094 service provider VLAN groups with each group
containing up to 4,094 customer VLANs. This allows a service provider to provide different services,
based on specific VLANs, for many different customers.
The line card drops any tagged frames received on the DTPVC. DTPVCs support DHCP relay, IGMP,
IEEE 802.1x and PPPoE agent. See
and Section 9.11 on page 255
Click Port > DTPVC to view and configure DTPVCs for ADSL, SHDSL, or VDSL2 (operating in
ADSL2+ connection mode) subscriber ports.
