mls qos input-queue
Configures the scheduling algorithm for one or more input fabric queues. If the scheduler is
weighted round robin (WRR), a weighting can also be specified. You must specify at least one
queue when setting this command.
The
no
variant of this command resets the scheduling algorithm for one or more input fabric
queues. Default is priority.

Usage
Queues may be serviced in either priority sequence or a weighted round-robin sequence. By
default all queues are set to priority servicing.
Priority Sequencing
In this mode the queue with the highest number, i.e. queue 3 will be emptied first, then queues
2, 1 and 0. Note that the lower queues will only be serviced if there is no data waiting in the
higher numbered queues.
Weighted Round Robin Sequencing
In this mode the weighting that you assign to each queue will determine how often it is serviced
with respect to the other WRR queues. For example, if queue 0 is configured with a weight of
5 and queue 1 is configured with a weight of 1, then queue 0 will be serviced 5 times more
than queue 1. Setting all weights to the same value will therefore apply an unweighted round
selection method.
Mixed Sequencing
If you configure the queues with a mix of priority queueing and WRR, the priority queues will
be completely emptied, before the any WRR queue is serviced.
Parameter
Description
mls
Multi-Layer Switch(L2/L3)
qos
Quality of Service
input-queue
The one or more input queues being configured by this command
0, 1, 2, 3
Input queues being configured
priority
Applies strict priority queue servicing to the selected queues
wrr
Applies weighted round robin queue servicing to the selected queues
weight
Specify weight for weighted round robin selection. Queues will then be
serviced in proportion to their applied weights. See

Returns the selected ports to priority queueing
