The following section lists the commands for this feature 178
Weighted fair queuing wfq guarantees each queue s minimum bandwidth based on its bandwidth weight portion when there is traffic congestion wfq is activated only when a port has more traffic than it can handle queues with larger weights get more guaranteed bandwidth than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues by default the weight for q0 is 1 for q1 is 2 for q2 is 3 and so on guaranteed bandwidth is calculated as follows 178
Weighted round robin scheduling wrr services queues on a rotating basis and is activated only when a port has more traffic than it can handle a queue is a given an amount of bandwidth based on the queue weight value queues with larger weights get more service than queues with smaller weights this queuing mechanism is highly efficient in that it divides any available bandwidth across the different traffic queues and returns to queues that have not yet emptied hybrid mode wrr spq or wfq spq some switch models allow you to configure higher priority queues to use spq and use wrr or wfq for the lower level queues 178
