Incoming Connections; Starting Ppp/Slip For Incoming Connections - Lantronix SCS Reference Manual

Basic Remote Networking
To set a site's IP RIP metric, use the Define Site IP RIP Metric command.
Local>> DEFINE SITE irvine IP RIP METRIC 4
In the example above, all routes learned through site irvine will be associated with cost 4. The higher the
cost number, the less desirable the route.
If IP RIP sending is disabled on a site, the Update and Metric values will be

4.5 Incoming Connections

This section describes how the SCS deals with incoming connections. When a remote device or network
tries to connect, the SCS forms a serial connection using its asynchronous serial lines. A protocol is then run
on this serial connection to allow network packets to be sent.
The SCS supports the use of PPP and SLIP to send network packets.
PPP
SLIP
PPP is enabled by default, while SLIP is disabled by default. To change these settings, use the Define Ports
PPP and Define Ports SLIP commands. For more information on these commands, see Port Modes on page
8-3.
Local>> DEFINE PORT 2 PPP DISABLED
Local>> DEFINE PORT 2 SLIP ENABLED

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.
For a description of the port modes, see Port Modes on page 8-3.
Note:
Figure 4-17: Configuring a Site's RIP Metric
The Point to Point protocol (PPP) is recommended whenever possible. PPP
enables devices to simultaneously transport IP packets, negotiate certain
options, authenticate users, and use checksums with virtually no performance
loss.
The Serial Line Internet Protocol (SLIP) is supported primarily for backwards
compatibility with equipment that does not support PPP. SLIP can only
transport IP packets—it does not support negotiation of IP address or other
options, nor does it provide any diagnostic facilities.
