4.5.1 Starting PPP/Slip for Incoming Connections
When you initiate an incoming LAN to LAN or remote node connection, you can start PPP or SLIP one of
several ways:
◆ The caller may be presented with a Local> prompt (the port will be in character mode), requiring him
to enter commands in order to run PPP or SLIP.
Note: For a description of the port modes, see Port Modes on page 8-3.
◆ The port may detect when a PPP or SLIP packet is received and automatically run the appropriate
protocol.
◆ The port may be dedicated to PPP or SLIP; the protocol will automatically run when any character is
received.
A port may be configured to offer a combination of these methods, giving the incoming remote node or
router flexibility in how the connection is started.
To configure the SCS for incoming LAN to LAN and remote node connections, see Configuring Incoming
Connections on page 4-13.
4.5.1.1 Starting PPP or SLIP from the Local> Prompt
You can enter the Set PPP and Set SLIP commands at the Local> prompt. The remote router or node must
then pass through the authentication procedures, if enabled, on the port in character mode. The remote
device must support chat scripts or must rely on a user to enter the required information and type Set PPP
or Set SLIP at the Local> prompt.
Note: For a complete description of authentication, refer to Chapter 11, Security. For
information on chat scripts, see Chat Scripts on page 5-3.
If no site name is given in the Set PPP or Set SLIP command, a temporary copy of the default site will be
started. If a custom site is to be started, it can be specified as a string: Set PPP sitename.
Note: To prevent users from starting inappropriate sites, users can be prompted for the
site’s local password.
To use the Set PPP and Set SLIP commands, enable PPP and/or SLIP on the port used for the connection.
See Incoming Connections on page 4-9.
