Viewing Traffic Control Policies

This operation enables you to view basic information about traffic control policies.


Two types of traffic control policies are available:

  • Upper-limit traffic control policy: controls the maximum bandwidth and IOPS.
  • Lower-limit traffic control policy: controls the minimum bandwidth and IOPS and maximum latency.

You can configure lower-limit traffic control policies only for file systems with a high I/O priority, and must not change the priorities of the file systems that are working with lower-limit traffic control policies.


  1. Choose Provisioning > Resource Performance Tuning > SmartQoS and click the Traffic Control tab page.
  2. View the information about traffic control policies.
