Configuring Rate Limiting on the Management Interface

Configuring Rate Limiting on the Management Interface


If there is heavy traffic on the management interface due to attacks or network exceptions, the CPU of the device is overloaded, which affects system operations. You can configure a rate limit on the management interface to limit the rate of traffic entering the device through the management interface, ensuring normal system operations.


  1. Run system-view

    The system view is displayed.

  2. Run interface ethernet 0/0/0

    The management interface view is displayed.

  3. Run qos lr pps packets

    A rate limit is set for the management interface.


    A small rate limit may affect the FTP, Telnet, SFTP, STelnet, and SSH functions.
