55.3 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.

55.3.1 PVC Set Command

The following example sets a PVC on ADSL port 1 with VPI 1, VCI 34, default VID 100 and

priority 3. It sets the “platinum” profile for downstream traffic shaping and a VC profile

named “plus” for upstream traffic policing.

55.4 Priority-based PVCs

A PPVC (Priority-based PVC) allows you to give different priorities to PVCs that are

members of the same VLAN.

The IES-612-51 uses eight priority queues (also called levels) for the member PVCs. The

system maps frames with certain IEEE 802.1p priorities to a PVC with a particular priority

queue. See Table 169 on page 391 for the factory default mapping.

Table 144 PVC Commands

COMMAND DESCRIPTION P

adsl pvc show

[<portlist>[<vpi><vci>]]

Displays the Permanent Virtual Circuit (PVC) parameters of the

specified ADSL port(s) or all of the ADSL ports if you do not specify

any.

M/L

adsl pvc set

<portlist><vpi><vci><super|

vlanid<priority>><ds-

vcprofile[,us-vcprofile]>

Allows the configuration of a PVC (permanent virtual circuit) for one

or a range of ADSL ports.

super: Enable the super channel option to allow a channel to

forward frames belonging to multiple VLAN groups (that are not

assigned to other channels). The IES-612-51 forwards frames

belonging to VLAN groups that are not assigned to specific channels

to the super channel. The super channel functions in the same way

as the channel in a single channel environment. One port can have

only one super channel.

H/H

adsl pvc delete

[<portlist>[<vpi><vci>]]

Deletes the specified PVC channel. H/H
