Configuring Rate Limiting on a Physical Interface

Configuring Rate Limiting on a Physical Interface

Pre-configuration Tasks

WAN-side physical interfaces support rate limiting. You can limit the rate of outgoing packets on a WAN-side physical interface by setting the percentage of traffic against the interface bandwidth.

Before configuring rate limiting on a physical interface, configure link layer attributes of the interface to ensure that the interface works properly.

Procedure

  1. Run system-view

    The system view is displayed.

  2. (Optional) Run qos overhead layer { link | physics }

    A mode is specified for calculating packet lengths during traffic policing or traffic shaping.

    By default, the system counts the physical-layer and link-layer compensation information in packet lengths during traffic policing or traffic shaping.

  3. Run interface interface-type interface-number

    The interface view is displayed.

  4. Run qos lr pct pct-value [ cbs cbs-value ]

    The percentage of the traffic rate against the interface bandwidth is set.

    By default, the percentage of traffic rate against the interface bandwidth is 100.

    NOTE:

    Rate limiting will not take effect until queue scheduling is configured.

Verifying the Configuration

  • Run the display this command on the interface to check the rate limiting configuration.
