Usage Information

Guarantee a minimum bandwidth to different queues globally using the service-class bandwidth-percentage command from CONFIGURATION mode. The command is applied in the same way as the bandwidth-percentage command in an output QoS policy. The bandwidth-percentage command in QOS-POLICY-OUT mode supersedes the service-class bandwidth-percentage command.

When you enable ETS, the egress QoS features in the output QoS policy-map (such as service-class bandwidth-percentage and bandwidth-percentage), the default bandwidth allocation ratio for egress queues are superseded by ETS configurations. This is to provide compatibility with DCBX. Therefore, Dell Networking OS recommends disabling ETS when you wish to apply these features exclusively. After you disable ETS on an interface, the configured parameters are applied.
