Advanced Configuration Options

Model 2160 Series Getting Started Guide 

In the Scheduling Configuration table, you can set up the type of QoS operation from 1 to 3. You can also set 
up the Queue Weight from 1 to 15.

WRR Scheduling Configuration Example. For example, you 
can set the Model 2160 use Weighted Round-Robin (WRR) queu-
ing that specifies a relative weight of each queue. WRR uses a pre-
defined relative weight for each queue that determines the 
percentage of service time to services each queue before moving on 
to the next queue. This prevents the head-of-line blocking that can 
occur with strict priority queuing.

For this example, set up the WRR (Type 1) to share bandwidth by using scheduling weights 1, 2, 4 and 8 for 
queues 0 through 3 respectively.

According to above two tables, we can get the mapping QoS values to Egress Queues as the following:ely.
