The following example creates a virtual channel profile named economy that uses LLC
encapsulation. It uses unspecified bit rate and has the maximum rate (peak cell rate) set to
50,000 cells per second. The acceptable tolerance of the difference between a cell’s transfer
delay and the expected transfer delay (CDVT) is set to 100 cells.

53.2.3 Delete Virtual Channel Profile Command
Syntax:
ras> adsl vcprofile delete <vcprofile>
where
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.

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.
