encapsulation. It uses unspecified bit rate and has the maximum rate (peak cell rate) set to

You cannot delete a virtual channel profile that is assigned to any of the DSL ports. Assign a

different profile to any DSL ports that are using the profile that you want to delete, and then

you can delete the profile.

The following example deletes the silver virtual channel profile.

53.3 PVC Channels

Channels (also called Permanent Virtual Circuits or PVCs) let you set priorities for different

services or subscribers. You can define up to eight channels on each DSL port and use them

for different services or levels of service. You set the PVID that is assigned to untagged frames

received on each channel. You also set an IEEE 802.1p priority for each of the PVIDs. In this

way you can assign different priorities to different channels (and consequently the services

that get carried on them or the subscribers that use them). Use the following commands to

define channels.
