where
You cannot delete a virtual channel profile that is assigned to any of the ADSL ports. Assign a
different profile to any ADSL 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.
56.3 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.
56.3.1 PVC Show Command
Syntax:
ras> adsl pvc show [<portlist> [<vpi> <vci>]]
where
This command allows you to display the PVC parameters of the specified ADSL port(s) or all
of the ADSL ports if you do not specify any.
56.3.2 PVC Set Command
Syntax:
ras> adsl pvc set <portlist> <vpi> <vci> <super |vid = 1..4094 <priority>>
<DS vcprofile[,US vcprofile]>
where
<vcprofile> =
The name of the virtual channel profile (up to 31 ASCII characters). You
cannot delete the DEFVAL or DEFVAL_VC profiles.

<portlist> =
You can specify a single ADSL port <1>, all ADSL ports <*> or a list of
ADSL ports <1,3,5>. You can also include a range of ports <1,5,6~10>.
[<vpi> <vci>] = The VPI and VCI of an individual PVC.
<portlist> =
You can specify a single ADSL port <1>, all ADSL ports <*> or
a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.
<vpi> =
The VPI setting can be 0 to 255.
