Queue Policing
Label Description
Port The port number for which the configuration below applies.
Enable(E) Check to enable queue policer for individual switch ports
Rate
Configures the rate of each queue policer. The default value is 500 . This
value is restricted to 100 to 1000000 when the Unit is kbps , and is
restricted to 1 to 3300 when the Unit is Mbps .
This field is only shown if at least one of the queue policers is enabled.
Unit

5.6.6 Scheduling and Shaping
Port scheduling can solve performance degradation during network congestions. The
schedulers allow switches to maintain separate queues for packets from each source and
prevent specific traffic to use up all bandwidth. This page allows you to configure Scheduler
and Shapers for individual ports.
QoS Egress Port Scheduler and Shaper
Strict Priority
Strict Priority uses queues based only priority. When traffic arrives the device, traffic on the
highest priority queue will be transmitted first, followed by traffic on lower priorities. If there is
always some content in the highest priority queue, then the other packets in the rest of queues
will not be sent until the highest priority queue is empty. The SP algorithm is preferred when
the received packets contain high priority data, such as voice and video.
