Example: PPPoE Credit-Based Flow Control Configuration
Verifying Credit-Flow Control
Purpose
Action
42
The interfaces statement includes the radio-router attribute, which contains the
parameters used for rate-based scheduling and OSPF link cost calculations. It also
includes the credit attribute to indicate that credit-based packet scheduling is supported
on the PPPoE interfaces that reference this underlying interface. Interfaces that set the
encapsulation attribute support the PPPoE Active Discovery Grant (PADG) and PPPoE
Active Discovery Credit (PADC) messages in the same way that the radio-router attribute
provides active support for the PPPoE Active Discovery Quality (PADQ) message.
The credit interval parameter controls how frequently the router generates credit
announcement messages. For PPPoE this corresponds to the interval between PADG
credit announcements for each session.
This example shows a PPPoE credit-based flow control configuration.

Display PPPoE credit-flow control information about credits on each side of the PPPoE
session when credit processing is enabled on the interface.
