Parameter
wrr: Weighted round robin algorithm.
group1: Adds the queue to WRR priority group 1.
group2: Adds the queue to WRR priority group 2.
queue-id: Outbound queue ID, in the range of 0 to 7.
queue-weight: Queue weight, in the range of 1 to 255.
&<1-8>: You can input the queue-id and queue-weight parameters eight times at most.
Description
Use the queue-scheduler command to choose queue scheduling algorithm and
parameters.
Use the undo queue-scheduler command to restore the default setting, SP algorithm.
By default, SP algorithm is selected for all outbound queues at a port.
The switch supports eight outbound queues at a port, with different scheduling
algorithms for them. You can configure these queues into different scheduling groups:
SP group, WRR priority group 1 and group 2. For example, you can set queues 6 and 7
into SP group, queues 0, 1 and 2 into WRR priority group 1 and queues 3, 4 and 5 into
WRR priority group 2. Then a queue will be selected respectively for theses three
groups according to their own scheduling algorithms. Then these three selected
queues will scheduled in SP algorithm.
The queue weight is based on bandwidth. For example, if queues 0, 1 and 2 belong to
WRR priority group 1 and their weight is respectively as 20, 20 and 30, then in process,
the proportion of their respective weight in the whole bandwidth is 20:20:30
Example
# Set queues 0 to 5 in WRR algorithm, queues 0, 1 and 2 belong to group 1, with weight
respectively as 20, 20 and 30; queues 3, 4 and 5 belong to group 2, with weight
respectively as 20, 20 and 40. Set queues 6 and 7 in SP algorithm, the default one.
