WAN interfaces, then apply a service profile to the desired interface(s). Examples of this process are displayed in “PPP Port Configuration” on page 348.

Defining the Type and Location of a PPP Interface

To configure a PPP WAN port, you need to first define the type and location of one or more PPP WAN ports on your SSR. The following command line displays a simplified example of a PPP WAN port definition:

Define the type and location of a PPP WAN port.

port set <port> wan-encapsulation ppp speed <number>

If the port is an HSSI port that will be connected to a HSSI port on another router, you can specify clock <clock-source>in the definition. (This feature is supported on HSSI boards, part number SSR-HSSI-02-AA.)

Setting up a PPP Service Profile

Once you have defined the type and location of your PPP WAN interface(s), you can configure your SSR to more efficiently utilize available bandwidth for PPP communications.

Note: The SSR comes with a set of “default values” for PPP interface configuration settings, which means that setting up a PPP service profile is not absolutely necessary to begin sending and receiving PPP traffic on your SSR.

After you configure one or more service profiles for your PPP interface(s), you can then apply a service profile to active PPP WAN ports, specifying their behavior when handling

PPPtraffic. The following command line displays all of the possible attributes used to define a PPP service profile:
