(Optional)Configuring Grade-based Bandwidth Adjustment

(Optional)Configuring Grade-based Bandwidth Adjustment

You can configure grade-based bandwidth adjustment to optimize SQ resource usage.


The allowed sum of CIRs or PIRs of SQs on a device cannot be infinite. Therefore, if the sum of CIRs or PIRs of SQs has reached the maximum processing performance of the device, the user that is applying for SQ resources is prone to request denies. To resolve such problems, you can configure grade-based bandwidth adjustment to supplement bandwidth or reclaim bandwidth in real time so that SQ resource usage is optimized and bandwidth is guaranteed.

Perform the following steps on the router:


  1. Run system-view

    The system view is displayed.

  2. Run slot slot-id

    The slot view is displayed.

  3. Run qos bandwidth-adjustment { degrade-cycle cycle-num | upgrade-cycle cycle-num | monitor-number monitor-number | adjust-number adjust-number | disable-percent disable-value enable-percent enable-value | upgrade-threshold upgrade-value degrade-threshold degrade-value [ inbound | outbound ] }

    Parameters for grade-based bandwidth adjustment are configured.

  4. Run commit

    The configuration is committed.
