Point-to-point software compression can be configured on serial
interfaces that use PPP encapsulation. Compression is performed in
software and might significantly affect system performance.
Compression is not recommended if most of the traffic consists of
compressed files.</font></p>
<p>
<font face="Arial" size="2">To configure compression over PPP, enter
the following commands:
