Queue Scheduling
Configuration Example
Modify the correspondence between 802.1p priority levels and local priority levels
to change the mapping between 802.1p priority levels and queues so that packets
are put into outbound queues according to the new mapping. Use WRR algorithm
for the queues 0 to 5 at the port GE7/1/1. Set the queues 0, 1 and 2 into WRR
queue 1, with weight respectively as 20, 20 and 30; set the queues 3, 4 and 5 into
WRR queue 2, with weight respectively as 20, 20 and 40. The queues 6 and 7 use
the SP algorithm. See
Queue Scheduling for the default mapping.

2 Use the WRR algorithm for the queues 0 to 5. Set the queues 0, 1 and 2 into WRR
queue 1, with weight respectively as 20, 20 and 30; set the queues 3, 4 and 5 into
WRR queue 2, with weight respectively as 20, 20 and 40. Use SP algorithm for the
queues 6 and 7.
