3.27.2 QoS Port Policing Configuration

Use this command to configure the Port Policer settings for all switch ports. A Policer can limit the bandwidth of received frames. It is located in front of the ingress queue.

Command Syntax:

qos policer <rate> [ kbps | mbps | fps | kfps ] [ flowcontrol ]
Table 3-109. Command Description

Argument

Description

Parameter

<rate>

Controls the rate for the port policer. This value is restricted to 100–3276700 when the 'Unit' is kbps or fps, and 1–3276 when the 'Unit' is Mbps or kfps. The rate is internally rounded up to the nearest value supported by the port policer.

flowcontrol

If flow control is enabled and the port is in flow control mode, then pause frames are sent instead of discarding frames.

Default

Disabled.

Mode

Port List Interface mode

Usage

Configure the policer rate and enable flow control. To revert to the default, use the ‘no’ version of the command.

Example 1:

Set policer to 200 Mbps with flow control enabled on port 1.
