WAN interfaces, then apply a service profile to the desired interface(s). Examples of this
process are displayed in
“PPP Port Configuration” on page 330 .
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:
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
PPP traffic. The following command line displays all of the possible attributes used to
define a PPP service profile:
Define the type and location of
a PPP WAN port. port set
