Serial Line Internet Protocol (SLIP)

SLIP Sessions
Ports can be configured with Automatic Protocol Detection enabled or can be
dedicated only for SLIP/CSLIP connections. For ports that are dedicated for
SLIP/CSLIP connections, when you enable SLIP on a port, the port expects
only SLIP or CSLIP packets from the remote location. Each packet is
transformed into an IP packet and then forwarded to the destination Internet
address. All packets received from the local network, and destined for the
device or network connected to the port, are put in SLIP or CSLIP packets and
forwarded over the serial link.
To terminate a SLIP session, you disconnect the dial-up link or log out the
SLIP port through another port on the communication server. SLIP processing
terminates when you log out the port.
If a port has a dedicated connection to the remote location, you can use the
DEFINE PORT INTERNET SLIP ENABLED command to establish a
permanent SLIP link. In this case, the only way to disable SLIP on the port is to
use the DEFINE PORT INTERNET SLIP DISABLED command and then log
the port out from another port.
Example Configurations
The Multiprotocol software supports two models for the utilization of SLIP: the
single-node model and the network model.
Single-Node Applications
Direct Connection of a Host to a Serial Port
This configuration is used to connect a host, workstation, or PC directly to the
network through a connection to a serial port. One might use this configuration
in order to connect a host that does not have an Ethernet connection to the
network. Figure 5-1 depicts this configuration.
To configure this connection, assign the local Internet address to the SLIP port.
The remote device supplies its own address. Since the idea is to allow the
remote device to be part of the network, a special SLIP network-mask (subnet
mask) variable is not needed. The communication server will assign
255.255.255.255 as the SLIP network mask.
For example, to assign a local address of 182.13.130.1 to port 8 of the
communication server shown in Figure 5-1, and assign no remote-address
(meaning that the remote device must supply its own address) or special
network-mask variable, use this command:
TS3395>> define port 8 internet slip address 182.13.130.1
NOTE:
If this is a DTE-to-DTE connection, the configuration will use
“null-modem” cabling.
