Configuring Default Ringlet Selection; Configure The Rpr Fairness Algorithm; Configuring Reserved Bandwidth Or Rate Limiting - HPE FlexNetwork HSR6800 series Configuration Manual

Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Add a static ringlet selection
entry.
NOTE:
Static ringlet selection entries take effect only when the RPR ring is closed.

Configuring default ringlet selection

Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Configure default ringlet
selection.
NOTE:
When a span is faulty and unable to forward data on the default ringlet configured, another ringlet
works as the default ringlet.

Configure the RPR fairness algorithm

By configuring the RPR fairness algorithm, you can better guarantee the transmission quality over
RPR rings.

Configuring reserved bandwidth or rate limiting

RPR traffic includes three classes: class A, class B, and class C, with decreasing priorities.
•
Class A is further divided into two subclasses: A0 and A1. RPR can reserve bandwidth for
subclass A0. When congestion occurs, the unused reserved bandwidth cannot be used by
lower priority traffic. Subclass A1 is rate limited. When congestion occurs, subclass A1 allows
lower priority traffic to use its unused bandwidth, and bandwidth allocation is regulated by the
fairness algorithm.
•
Class B can also be divided into two subclasses: B-CIR and B-EIR. For class B traffic, the
portion within the predefined rate limit belongs to class B-CIR and the portion exceeding the
limit belongs to class B-EIR. Similar to traffic of class C, traffic of class B-EIR is regulated by the
fairness algorithm.
•
Traffic of class C is regulated by the fairness algorithm and takes the lowest priority.
To configure reserved bandwidth or rate limit for a certain traffic class:
Step
1. Enter system view.
