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.
