Configuring Timers - H3C S9500 Series Operation Manual

Operation Manual – RPR
H3C S9500 Series Routing Switches
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 2.
Follow these steps to assign the bandwidth allocation fairness weight to the RPR
station on a ringlet:
Enter system view
Enter RPR logical
interface view
Configure the weight of
the station
