Queue Scheduling
Modify the correspondence between 802.1p priority levels and local priority levels
to change the mapping between 802.1p priority levels and queues. That is, put
packets into outbound queues according to the new mapping. Use WRR
algorithm, and the weight for different queues is respectively 5, 5, 10, 10, 15, 15,
9 and 9. The mapping between the modified 802.1p priority levels and the local
priority levels is listed in the following figure (See Queue Scheduling for the default
mapping).
The 20-Port 10/100/1000BASE-T and 20-Port 1000BASE-X-SFP I/O modules
support SP, WRR and RR algorithm.
Other interface units support only SP algorithm.

To create this configuration:
1 Respecify mapping between 802.1p priority levels and local priority levels.

2 Define WRR algorithm for the switch and specify the weight of outbound queues
as 5, 5, 10, 10, 15, 15, 9 and 9.
