Figure 11-12 CoS Queue Group Configuration Window—DRR Tab
The DRR tab has two areas: DRR Mapping and DRR Queue. There is also a Low-latency field.
DRR Mapping
The DRR Mapping area allows you to map a particular IP precedence to a regular DRR queue (values
0-6 or low-latency).
DRR Queue
The DRR Queue area allows you to give a relative weight to each DRR queue.
Low-latency—Only applicable for MDRR. This value can be set to one of the following values:
Alternate priority—You must specify a weight in the DRR queue area.
Strict priority—No weight is specified.
None—If low latency is not mapped to any of the IP Precedences in the DRR Queue, then you must
set the low latency to none.
