Option Description
VJ Compression This determines whether Van Jacobson compression is used on this link; i.e.
whether you are using SLIP or C-SLIP (compressed SLIP). The choices are 'on'
(C-SLIP) or 'off' (SLIP); the default is 'on'. Select 'on' will turn on VJ
compression. C-SLIP greatly improves the performance of interactive traffic,
such as Telnet or Rlogin; see
information.
In the cli, example syntax would be: set slip li 1 vj on.
If your user is authenticated by the unit this VJ compression value will be
overridden if you have set a 'framed compression' value for a user; see
Configuring a user account on page
If your user is authenticated by RADIUS and the RADIUS parameter 'Framed-
Compression' is set in the RADIUS file the unit will use the value in the
RADIUS file in preference to the 'VJ compression' value configured here.
TX parameters Meaning Transmit parameters. This will output to the screen of the user all the
SLIP parameters configured for that line/port. TX parameters are useful in some
applications such as Trumpet Winsock. Options are 'on' or 'off'.
