Configuring Group-based WRR Queues 849
Configuring
Group-based WRR
Queues
With a queue on a port configured as a group-based WRR queue, the queue
scheduling algorithm on the current port is the mix of WRR queue scheduling
algorithm and SP queue scheduling algorithm. The queues which are not
configured as group-based WRR queues are allocated to the SP queue group.
Configuration Procedure Group-based WRR queue configuration task list
Follow these steps to configure group-based WRR queues:
n
■ POS interfaces do not support WRR.
■ In group-based WRR queue configuration, the outgoing ports of 3C17526,
3C17532, and 3C17538 modules support four queues, that is, the queue-id
argument is in the range of 0 to 3; this argument is in the range of 0 to 7 for
the other modules.
Configuration Examples Network requirements
■ Configure the queues on a port as WRR queues.
■ Allocate queue 1, queue 3, and queue 4 to WRR group 1, with the weight 1, 5,
and 10.
■ Allocate queue 5 and queue 6 to WRR group 2, with the weight 20 and 10.
