Line Service Commands

ruser

This field is used to authenticate a user connecting to this line. It is used in conjunction
with the

rpassword

field. By specifying a name here, this line becomes dedicated to

that user only. If left blank, the internal user database will be used to authenticate the
connection and any user configured will be able to access this line. You can enter a
maximum of sixteen alphanumeric characters.

This option does not work with external authentication.

authentication

The type of authentication that will be done on the link:

None

,

PAP

, or

CHAP

. The

default is

CHAP

. You can use

PAP

or

CHAP

to authenticate a port or user on the

IOLAN, from a remote location, or authenticate a remote client/device, from the
IOLAN (not commonly used for

Dial Out

).

PAP is a one time challenge of a client/device requiring that it respond with a valid
username and password. A timer operates during which successful authentication must
take place. If the timer expires before the remote end has been authenticated
successfully, the link will be terminated.

CHAP challenges a client/device at regular intervals to validate itself with a username
and a response, based on a hash of the secret (password). A timer operates during which
successful authentication must take place. If the timer expires before the remote end has
been authenticated successfully, the link will be terminated.

When setting either

PAP

and

CHAP

, make sure the IOLAN and the remote client/device

have the same setting. For example, if the IOLAN is set to

PAP

, but the remote end is

set to

CHAP

, the connection will be refused.

tr-retry

The maximum number of times a

terminate request

packet will be re-sent before

the link is terminated.

tr-tmout

The maximum time, in seconds, that LCP (Link Control Protocol) will wait before it
considers a

terminate request

packet to have been lost.

user

This field is used by a remote peer to authenticate a PPP connection on this line. It is
used in conjunction with the

password

field. You can enter a maximum of sixteen

alphanumeric characters.

vj-comp

This determines whether Van Jacobson Compression is used on this link. The default is

On

. If your user is authenticated by the IOLAN, this VJ compression value will be

overridden if you have set the

User Framed Compression On

. If your user is

authenticated by RADIUS and the RADIUS parameter

Framed-Compression

is set in

the RADIUS file, the IOLAN will use the value in the RADIUS file in preference to the
value configured here.
