Serial Port Profiles

IPv6 Remote	The remote IPv6 interface identifier of the remote end of the PPP link. Choose
Interface Identifier	an address that is part of the same network or subnetwork as the IOLAN. If
	you enable Negotiate IP Address Automatically, the IOLAN will ignore the
	remote IP address value you enter here and will allow the remote end to
	specify its IP address. If your user is authenticated by RADIUS and the
	RADIUS parameter Framed-Interface-IDis set in the RADIUS file, the
	IOLAN will use the value in the RADIUS file in preference to the value
	configured here.
	Field Format: The first 64 bits of the Interface Identifier must be zero,
	therefore, ::abcd:abcd:abcd:abcd is the expected format.
ACCM	Specifies the ACCM (Asynchronous Control Character Map) characters that
	should be escaped from the data stream.
	Field Format: This is entered as a 32-bit hexadecimal number with each bit
	specifying whether or not the corresponding character should be escaped. The
	bits are specified as the most significant bit first and are numbered 31-0. Thus
	if bit 17 is set, the 17th character should be escaped, that is, 0x11 (XON). The
	value 000a0000 will cause the control characters 0x11 (XON) and 0x13
	(XOFF) to be escaped on the link, thus allowing the use of XON/XOFF
	(software) flow control. If you have selected Soft Flow Control on the Serial
	Port, you must enter a value of at least 000a0000 for the ACCM.
	Default: 00000000, which means no characters will be escaped
MRU	The Maximum Receive Unit (MRU) parameter specifies the maximum size of
	PPP packets that the IOLAN’s port will accept. If your user is authenticated by
	the IOLAN, the MRU value will be overridden if you have set a MTU value for
	the user. If your user is authenticated by RADIUS and the RADIUS parameter
	Framed-MTUis set in the RADIUS file, the IOLAN will use the value in the
	RADIUS file in preference to the value configured here.
	Range: 64-1500 bytes
	Default: 1500
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
