Weighted Round-Robin of Subscriber Traffic on a Port Limitations

The following list describes the limitations for WRR:

  • The delay-buffer rate must be configured for WRR to work correctly.

  • A discrepancy in the delay-buffer rate values among the VLANs belonging to the same level 2 scheduler node can cause the WRR to work incorrectly.

  • WRR does not work correctly if the ratio of the shaping rate is greater than 100 among all the subscribers.

  • The number of level 2 scheduler nodes and the number of subscribers per level 2 scheduler node must be equal to 32,000 for it to work correctly.

  • Any modification to the level 2 scheduler node configuration requires an FPC reset.
