Configuring Traffic Policing

Configuring Traffic Policing

Context

To protect network resources and prevent network congestion, configure traffic policing to limit the rate of traffic entering the WLAN.

Traffic policing on a WLAN can be configured in a traffic profile or user profile.

Monitored Object

Description

Command

SSID-based QoS CAR

If the QoS CAR in an SSID profile is set to car-value, the total bandwidth of all the STAs associating with all the VAPs with this SSID profile bound does not exceed car-value.

qos car (SSID profile view)

Rate limiting for a single VAP

If the rate limit in a traffic profile is set to limit, the total bandwidth of all the STAs associating with a single VAP with this SSID profile bound does not exceed limit.

rate-limit vap { up | down } rate-value

Rate limiting for a single STA

If the rate limit in a traffic profile is set to limit, the bandwidth of a single STA with a VAP with this SSID profile bound does not exceed limit.

rate-limit client { up | down } rate-value

Pre-configuration Tasks

Before configuring traffic policing, perform the task of WLAN Service Configuration.

Procedure

  • Configure traffic policing in a traffic profile.
    1. Run:

      system-view

      The system view is displayed.

    2. Run:

      wlan

      The WLAN view is displayed.

    3. Run:

      traffic-profile name profile-name

      A traffic profile is created and the traffic profile view is displayed.

    4. Run:

      rate-limit { client | vap } { up | down } rate-value

      The rate limit is configured for upstream and downstream traffic of all STAs or a single STA on a VAP.

      • By default, the rate limit for upstream and downstream traffic of all STAs on a VAP is 4294967295 kbit/s.

      • By default, the rate limit for upstream and downstream traffic of a single STA on a VAP is 4294967295 kbit/s.

    5. Run:

      quit

      Exit from the traffic profile view.

    6. Run:

      vap-profile name profile-name

      The VAP profile view is displayed.

    7. Run:

      traffic-profile profile-name

      A traffic profile is bound to the VAP profile.

      By default, the traffic profile default is bound to a VAP profile.

    8. Run:

      quit

      Return to the WLAN view.

    9. Run:

      commit { all | ap-name ap-name | ap-id ap-id }

      The configurations are delivered to APs.

  • Configure traffic policing in an SSID profile.
    1. Run:

      NOTE:

      QoS CAR parameters configured in an SSID profile are valid only when the service data forwarding mode is set to tunnel forwarding.

      system-view

      The system view is displayed.

    2. Run:

      wlan

      The WLAN view is displayed.

    3. Run:

      ssid-profile name profile-name

      The SSID profile view is displayed.

    4. Run:

      qos car inbound cir cir-value [ cbs cbs-value [ pbs pbs-value ] | pir pir-value [ cbs cbs-value pbs pbs-value ] ]

      QoS CAR parameters are configured.

      By default, no QoS CAR parameters are configured in an SSID profile.

    5. Run:

      quit

      Return to the WLAN view.

    6. Run:

      commit { all | ap-name ap-name | ap-id ap-id }

      The configuration is delivered to APs.

Verifying the Configuration

  • Run the display traffic-profile { all | name profile-name } command to check the configuration of the rate limit for upstream and downstream traffic of the STAs on the VAP in the traffic profile.

  • Run the display ssid-profile { all | name profile-name } command to check QoS CAR parameter settings in the SSID profile.
