Serial Line Internet Protocol (SLIP)
Configuring Ports for SLIP mode
If you want to use these SLIP lines as normal CLI dial-up lines, that is, entering the slip command
puts the lines into SLIP mode, set the mode parameter to cli, adaptive, auto_detect, or auto_adapt:
admin: port 1–4
admin: set port mode cli speed 38400 control_lines both
admin: input_flow_control eia output_flow_control eia
admin: type dial_in
Configuring SLIP for Dial-out
Dial-out SLIP allows system administrators to define a database of information about a modem pool
and a set of virtual dial-out routes. The Model 5390 server assigns each virtual dial-out route
dynamically to ports in that pool. Each virtual dial-out route must be configured within the Model
5390 configuration file to start the SLIP line (for more details, see Dial-out Routes on page A14-42).
Dial-out SLIP also provides:
• On-demand dialing by logically tying the phone number to the virtual route.
• Dial-on-demand network routing by having the Model 5390 dial-out routes configured with
the proper static network routes (thus, the Model 5390 server can route traffic to a particular
network through a dial-out route's destination).
• The use of chat scripts (a sequence of commands that are used to log into the remote system
after the phone connection is established and before the IP framing protocol begins; for more
details, see Chat Scripts on page A14-43).

NOTE: Dial-out routes are defined in the Model 5390 configuration
file. Setting Up the Configuration File on page A14-5 provides a sample
configuration file; Creating dialout Entries in the Configuration File on
page A14-37 describes how to create dialout entries in the configura-
tion file. Dial-out SLIP applies only to IP framing protocols; it does not
apply to other protocols (for example, ARAP, IPX, etc.). Setting a port
to provide dial-out SLIP requires that you configure the port for both an
outgoing modem and a SLIP link (see Configuring SLIP for Dial-in on
page A7-10 for sample parameter settings). Set the mode parameter to
slave, adaptive, or auto_adapt.
