ONFIGURATION
Introduction to SLIP
SLIP (Serial Line Internet Protocol) defines a method of forwarding packets via
standard RS-232 asynchronous serial line.
standard RS-232 asynchronous serial line.
The advantage of SLIP lies in its inexpensive price. It enables a computer to access
the Internet by dialing-up without dedicated line. Furthermore, as SLIP does not
provide address, or error detection and correction, or compression algorithm, it is
simple for implementation.

Please note that SLIP does not recognize packet types, which makes it only
capable of supporting one kind of network protocol at one time.

For more detailed introduction about SLIP, refer to RFC1055.
Configuring SLIP
As SLIP does not negotiate the peer name, SLIP dialing can only coordinate with
standard DCC.
standard DCC.
SLIP configuration includes:
■
Configure synchronous/asynchronous interface to work in asynchronous mode
■
Configure the link layer protocol of an interface to be SLIP
■
Configure the incoming and outgoing call authority of Modem
■
Enable DCC
■
Activate Dialer Group and Dialer Rule
■
Configure dialing string on an interface
For specified configuration about DCC and Modem, refer to the module about
“Dialing-up”.
“Dialing-up”.
