Command
History
Version 9.2(0.0) Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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the default bandwidth allocation ratio for egress queues are superseded by ETS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.
