Configuring Station Weight; Configuring Rpr Timers; Configuring The Atd Timer - HPE FlexNetwork HSR6800 series Configuration Manual

Step
2. Enter RPR logical
interface view.
3. Configure reserved
bandwidth or rate limit
for a class on a certain
ringlet.
NOTE:
The total bandwidth reserved for subclass A0 by the stations on a ringlet must be less than the
ringlet bandwidth.

Configuring station weight

On an RPR ring, bandwidth resources are shared among stations. When traffic size is small, RPR
can handle bandwidth requests of all stations on the ring. When traffic size gets heavy, congestion
might occur. To prevent some stations from taking advantage of their spatially or chronologically
favorable position on the ring to occupy excessive bandwidth, RPR adopts a fairness algorithm to
ensure bandwidth allocation fairness.
The fairness algorithm of RPR mainly regulates class B-EIR and class C traffic on the RPR ring. You
can assign a weight to a station to adjust the ratio of its available service bandwidth to the total
non-reserved bandwidth on a ringlet. The fairness weight of a station is configured as an exponent of
two.
To configure the fairness weight of an RPR station on a ringlet:
Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Configure the weight of the
station.

Configuring RPR timers

Configuring the ATD timer

The ATD timer defines the interval at which attribute discovery frames are sent.
To configure the ATD timer:
Step
1. Enter system view.
2. Enter RPR logical interface
view.
3. Set the ATD timer.

By default, no bandwidth is reserved for
subclass A0. The rate limit is 2‰ for
subclass A1, 0‰ for class B-CIR, and
1000‰ for B-EIR and class C.
