HQoS scheduler policy
HQoS is configured by first defining the HQoS scheduler policies and then mapping them to the
physical ports. The same HQoS scheduler policy can be applied to multiple ports to enable
provisioning.
To build a complete HQoS scheduler, you must define the types of scheduler elements used by the
HQoS hierarchy at each hierarchy level.
shows the elements that must be configured for the HQoS policy.
