Virtual Channel Management

This chapter shows you how to use commands to configure virtual channels.

26.1About Virtual Channels

See the web configurator chapter on virtual channel management for background information on virtual channels. The configuration of virtual channels is the same for both the AAM and SAM network modules.

26.2Virtual Channel Profile Commands

Use the following commands to configure virtual channel profiles.

26.2.1Set VCP Command

The syntax is as follows whenever the class is cbr or ubr.

192.168.1.1 adsl> set vcp <profile name> <encap> <aal> <class> <pcr> <cdvt> [<scr/mcr> <bt/nrm>]

The syntax is as follows whenever the class is rt-vbr or nrt-vbr.

192.168.1.1 adsl> set vcp <profile name> <encap> <aal> <class> <pcr> <cdvt> <scr> <bt>

The syntax is as follows whenever the class is abr.

192.168.1.1 adsl> set vcp <profile name> <encap> <aal> <class> <pcr> <cdvt> <mcr> <nrm>

where

<encap>

The type of encapsulation (llc or vc).

<aal>

The ATM Adaptation Layer (aal0, aal3, aal4 or aal5).

<class>

=

The type of ATM traffic class: cbr (constant bit rate), rt-vbr (real-time variable bit

 

 

rate), nrt-vbr (non real-time variable bit rate), ubr (unspecified bit rate) or abr

 

 

(available bit rate).

<pcr>

=

The Peak Cell Rate (0 to 300000 or *), the maximum rate at which the sender can
