Advanced Tab Field Descriptions
Configure the following parameters:
MTU The Maximum Transmission Unit (MTU) parameter restricts the size of
individual SLIP packets being sent by the IOLAN. Enter a value between 256
and 1006 bytes; for example, 512. The default value is
256. If your user is
authenticated by the IOLAN, this MTU value will be overridden when you
have set a
Framed MTU value for the user. If your user is authenticated by
RADIUS and the RADIUS parameter
Framed-MTU is set in the RADIUS file,
the IOLAN will use the value in the RADIUS file in preference to the value
configured here.
Default: 256
Routing Determines the routing mode (RIP, Routing Information Protocol) used on the
SLIP interface as one of the following options:
z None—Disables RIP over the SLIP interface.
z Send—Sends RIP over the SLIP interface.
z Listen—Listens for RIP over the SLIP interface.
z Send and Listen—Sends RIP and listens for RIP over the SLIP interface.
This is the same function as the
Framed-Routing attribute for RADIUS
authenticated users.
Default: None
VJ Compression When enabled, Van Jacobson compression is used on this link. When enabled,
C-SLIP, or compressed SLIP, is used. When disabled, plain SLIP is used. C-
SLIP greatly improves the performance of interactive traffic, such as Telnet or
Rlogin.
If your user is authenticated by the IOLAN, this VJ compression value will be
overridden if you have set a
Framed Compression value for a user. 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.
Default: Enabled
Direct Connect If the device is remote and will be dialing in via modem or ISDN TA, enable
this parameter.
Default: Disabled
