Usage
Information
Use this command to specify the name of the output QoS policy. Once output policy is specified,
rate-shape, scheduler strict, bandwidth-percentage, and WRED can be defined. This command enables
the qos-policy-output configuration mode—(conf-qos-policy-out).
When rate-shape in QoS policy is applied both on queue level and aggregate mode, the queue-based
shaping occurs first followed by the aggregate rate shaping.
rate-police
s z
Specify the policing functionality on incoming traffic.

Parameters
Defaults
Burst size is 100 KB. peak-rate is by default the same as committed-rate. Granularity for
committed-rate and peak-rate is Mbps unless the kbps option is used.

S-Series make the following value a multiple of 64. On the Dell Networking
recommends using a value greater than or equal to 512 as lower values does not
yield accurate results. The default granularity is Megabits per second (Mbps).
Range: 0 to 40000

Enter the committed rate in Mbps.
Range: 0 to 40000 Mbps

(OPTIONAL) Enter the burst size in KB.
Range: 16 to 200000 KB
Default:100 KB
peak peak-rate
(OPTIONAL) Enter the keyword peak followed by the peak rate in Mbps.
Range: 0 to 40000 Mbps
