14 CONFIGURING SLIP
This chapter contains information on the following topics:
■SLIP Overview
■Configure SLIP
■Display and Debug SLIP
■Typical SLIP Configuration Example
SLIP Overview SLIP (Serial Link Internet Protocol) can transmit data over the asynchronous serial
link. Through SLIP, the user can dial up to access the Internet. Compared with
other link layer protocols, SLIP is very simple. It does not provide protocol address,
error check, header compression. In addition, SLIP does not distinguish packet
types, so it supports only one type of network protocol at one time.
For further details about SLIP, you can refer to RFC1055.
Configure SLIP Because SLIP does not negotiate the name of the remote end, SLIP dialer can only
be used with the standard BDR.
SLIP dialer on the physical port configuration includes:
■Configure the synchronous/asynchronous serial interface to asynchronous
mode
■Configure the incoming and outgoing call authorities of Modem
■Enable BDR
■Configure the link layer protocol of the interface to SLIP
■Configure Dialer Group and Dialer Rule of activated calls
■Configure the dial string of interface
For the specific configuration methods of BDR and Modem, please refer to related
chapters of BDR, Modem in Operation Manual – Dial-up.
