Quidway S3500 Series Ethernet Switches
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 0~7.
queue-weight: Queue weight, in the range of 1~255.
&<1-8>: You can input the queue-id and queue-weight parameters eight times at most.
Description
Using the queue-scheduler command, you can choose queue scheduling algorithm
and parameters. Using the undo queue-scheduler command, you can 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 3, 4 and 5 into WRR priority group 1 and queues 0, 1 and 2 into
WRR priority group 2. Then a queue will selected respectively from theses three groups
according to their own scheduling algorithms. Then these three selected queues will
scheduled in SP algorithm.
Note:
You must follow these rules to group eight outgoing queues at a port:
The queues in one group must have consecutive queue numbers. For example,
queue 3, 4 and 5 have consecutive queue numbers and thus can be grouped in one
queue scheduling group; whereas queue 3, 4 and 7 cannot be grouped in one
group.
You must group the queues with high priority in the SP group, the queues with
comparatively lower priority in the WRR1 group, and the queues with the lowest
priority in the WRR2 group. Ensure that the priorities of all the queues in SP are
higher than that of all the queues in WRR1, and the priorities of all the queues in
WRR1 are higher than that of all the queues in WRR2.
For the related command, see display queue-scheduler.
Example
# Set queues 0~5 in WRR algorithm, queues 0, 1 and 2 belong to group 2, with weight
respectively as 20, 20 and 10; queues 3, 4 and 5 belong to group 1, with weight
respectively as 20, 20 and 10. Set queues 6 and 7 in SP algorithm, the default one.
