type of line card you selected automatically displays.
Port Select the number of a DSL port on the line card.
Load Click Load to display the port’s DTPVC settings in the DTPVC Table .
Index This is the number of the DTPVC on this port.
VPI/VCI This field displays the Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI). The VPI
and VCI identify a channel on this port.
Profile This field displays the ATM profile that this channel uses.
MUX This field displays the encapsulation type ( llc or vc ) for this channel.
Type This field shows that the channel is a DTPVC ( dtag ).
SVID This is the service provider’s VLAN ID (the outer VLAN tag) that the line card assigns to
untagged frames received on this DTPVC.
SPri 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 DTPVC. "0" is the lowest priority level and "7" is
the highest.
CVID This is the customer VLAN ID (the inner VLAN tag) that the line card assigns to untagged
frames received on this DTPVC.
CPri 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 DTPVC. "0" is the lowest priority level and "7" is the
highest.
Mvlan This field displays the DTPVC’s current multicast VLAN setting. “-” indicates the multicast VLAN

VPI/VCI Type the Virtual Path Identifier and Virtual Circuit Identifier for a channel on this port.
Mvlan
Enable Select this option to send multicast VLAN traffic through this DTPVC.
Multicast VLAN allows one single multicast VLAN to be shared among different customer VLANs
on the network. This improves bandwidth utilization by reducing multicast traffic in the
subscriber VLANs and simplifies multicast group management.

ID (from 1 to 4094) for untagged frames received on this DTPVC.
SPri Enter the priority level for the service provider’s VLAN ID. "0" is the lowest priority level and "7"
is the highest.
CVID CVID refers to the customer VLAN ID (the inner VLAN tag). Enter the customer ID (from 1 to
4094) for untagged frames received on this DTPVC.
CPri Enter the priority level for the customer 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
