Configuring and Managing SLIP Ports
Compressed SLIP
Introduction
The access server has the ability to enable compressed SLIP (CSLIP). Enabling
CSLIP compresses the lengthy headers of IP datagrams on low-speed
asynchronous serial lines. Therefore, enabling CSLIP can improve performance.
Enabling CSLIP
Use the SET/CHANGE PORT n SLIP COMPRESSION command to enable or
disable CSLIP. By default, compression is disabled. When you enable CSLIP, make
sure that it is enabled at both ends of the communications link. If only one end of
the link is running CSLIP, performance degrades.
Example: Enabling CSLIP
The following example shows how to enable CSLIP on port 5:
Local> CHANGE PORT 5 SLIP COMPRESSION ENABLED
Disabling CSLIP
The following example shows how to disable CSLIP on a port:
Local> CHANGE PORT 5 SLIP COMPRESSION DISABLED
Automatic CSLIP
You can enable a port to start CSLIP automatically if the port receives compressed
data over an already existing SLIP session. The following example shows how to
enable automatic CSLIP on a given port:
Local> CHANGE PORT 5 SLIP COMPRESSION AUTOCOMPRESS
Compression States
You can specify the number of connections that can be compressed over the data
link at one time. The following example shows how to change the number of
compression states on a port:
Local> CHANGE PORT COMPRESSION STATES 10
The default number of compression states is 16.
