Configuring Users
Set Default User
Description Configures the Default User. When adding a new user, the profile of the default user
will be used to assign the values of the various parameters of the new user. For example
if you set the
service parameter of the default user to ppp , when a new user is added,
their service parameter will be set to ppp .

Options callback
When On , enter a phone number for the IOLAN to call the user back (the Callback
parameter is unrelated to the Line Dial parameter).
Note: the IOLAN will allow callback only when a user is authenticated. If the protocol
over the link does not provide authentication, there will be no callback. Therefore, when
the
Line Service is set to PPP , you must use either PAP or CHAP , because these
protocols provide authentication. The default is Off .
The IOLAN supports another type of callback, Roaming Callback , which is
configurable when the Line Service is set to PPP .
framed-compression
Used for User Service PPP or SLIP , determines whether Van Jacobsen Compression is
used on the link. VJ compression is a means of reducing the standard TCP/IP header
from 40 octets to approximately 5 octets. This gives a significant performance
improvement, particularly when interactive applications are being used. For example,
when the user is typing, a single character can be passed over the link with a packet as
small as 5 octets as opposed to 40 octets when no JV compression is used. VJ
Compression has little effect on other types of links, such as ftp, where the packets are
much larger. The
Framed Compression value will be used in preference to the VJ
Compression value set for a Line . The default is Off .
framed-ip
Used for User Service PPP or SLIP , sets the IP address of the remote user. Enter the
address in dot decimal notation as follows:
z 255.255.255.254 (default)—The IOLAN will use the Remote IP Address set in
the PPP settings for the line.
z 255.255.255.255 —When the User Service is PPP , the IOLAN will allow the
remote machine to specify its IP address (overriding the Remote IP Address
configured in the line,
PPP settings). When the User Service is SLIP , the IOLAN
will use the Remote IP Address set for the line (no negotiation).
z n.n.n.n —(where n is a number) Enter the IP address of your choice. This IP
address will then be used in preference to the Remote IP Address set for a line.
framed-interface-id
Used for User Service PPP , sets the IPv6 address of the remote user.
