processing by MLP. If compression is enabled on a link, the packets will be compressed
after the MLP processing.
In general, choose bundle compression over link compression whenever possible.
Compressing packets before they are “split” by MLP is much more efficient for both the
compression algorithm and the WAN card. Link compression is supported to provide the
widest range of compatibility with other vendors’ equipment.
Monitoring PPP WAN Ports
Once you have configured your PPP WAN interface(s), you can use the CLI to monitor
status and statistics for your WAN ports. The following table describes the monitoring
commands for WAN interfaces, designed to be used in Enable mode:
PPP Port Configuration
To configure PPP WAN ports, you must first define the type and location of the WAN
interface, optionally “set up” a library of configuration settings, then apply those settings
to the desired interface(s). The following examples are designed to give you a small model
of the steps necessary for a typical PPP WAN interface specification.
To define the location and identity of a High-Speed Serial Interface (HSSI) PPP WAN port
located at router slot 5, port 1 with a speed rating of 45 million bits per second:
Display a particular PPP service
profile.
ppp show service <service name>
Display all available PPP service
profiles.
ppp show service all
Display bridge NCP statistics for
specified PPP WAN port.
ppp show stats port <port name> bridge-
ncp
Display IP NCP statistics for
specified PPP WAN port.
ppp show stats port <port name> ip-ncp
Display link-status statistics for a
specified PPP WAN port.
ppp show stats port <port name> link-
status
Displays information for PPP ports
that are added to MLP bundles.
