8.1 Console object types

The ppp process presents its setup in terms of a number of distinct object types:

• The upper limit on the number of each of these objects permitted in a system is

configured using the config resource console command.

• The current state of each object is saved by config save.

8.1.1 Channels

The ppp process provides a number of PPP connection channels. A channel is a

single PPP connection. Channels are numbered from 1. Many ppp console

commands affect only a single channel. The command is prefixed with the channel

number.

8.1.2 Users

A user is a user name and password. All users must have distinct names. The user

console command controls these.

8.1.3 Tunnels

A tunnel is a PPTP or L2TP connection. Tunnels are numbered from 1. PPP

channels must be associated with a tunnel to be involved in PPP tunnelling. The

tunnel console command provides control of these.

8.1.4 Interfaces

An interface is an internal MAC (Ethernet) device. PPP channels must be associated

with an interface to be involved with bridging or routing.

8.1.5 Interface 1 and Channel 1

Interface 1 has some special functions associated with it, allowing dynamic IP

address assignment to be performed. Channel 1 is by default associated with

Interface 1. These two should be used only for IP dial-out functions, and for this

function should be attached to the router interface named ppp_device. The dial-out

example in the following section makes this clearer. These specializations have been

made to make the configuration of an IP dial-out simpler.

8.2 Console examples

8.2.1 Simple test

The simplest thing you can do to test ATMOS PPP, between two PPP channels in a

single ATMOS system, is to create a PVC in the switch to which the test box is

connected, between two VCIs (say 32 and 33 here) on the connected switch port.

Type the following:

1 2 ... 48 49 50 51 52 53 54 55 56 57 58 ... 111 112
