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:

Display a particular PPP service	ppp show service <service name>
profile.
Display all available PPP service	ppp show service all
profiles.
Display bridge NCP statistics for	ppp show stats port <port name> bridge-
specified PPP WAN port.	ncp
Display IP NCP statistics for	ppp show stats port <port name> ip-ncp
specified PPP WAN port.
Display link-status statistics for a	ppp show stats port <port name> link-
specified PPP WAN port.	status
Displays information for PPP ports	ppp show mlp <mlp list>all-ports
that are added to MLP bundles.

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:

ssr(config)# port set hs.5.1 wan-encapsulation ppp speed 45000000
