Authentication Tab Field Descriptions

Configure the following parameters:

Authentication	The type of authentication that will be done on the link. You can use PAP or
	CHAP to authenticate a serial port or user on the IOLAN, from a remote
	location, or authenticate a remote client/device, from the IOLAN.
	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.
	Data Options:
	z None
	z 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.
	z 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.
	Default: CHAP
User	Complete this field only if you have specified PAP or CHAP (security
	protocols) in the Authentication field, and
	z you wish to dedicate this line to a single remote user, who will be
	authenticated by the IOLAN, or
	z you are using the IOLAN as a router (back-to-back with another IOLAN).
	When Connect is set to Dial Out or both Dial In/Dial Out are enabled, the User
	is the name the remote device will use to authenticate a port on this IOLAN.
	The remote device will only authenticate your IOLAN’s port when PAP or
	CHAP are operating. You can enter a maximum of sixteen alphanumeric
	characters; for example, tracy201. When connecting together two networks,
	enter a dummy user name; for example, DS_HQ.
	Note If you want a reasonable level of security, the user name and password
	should not be similar to a user name or password used regularly to login to the
	IOLAN. External authentication can not be used for this user.
	Field Format: You can enter a maximum of 254 alphanumeric characters.
