9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
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the default bandwidth allocation ratio for egress queues are superseded by ETS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.

Usage Information
After you configure a unicast queue as strict-priority, that particular queue, on the
entire chassis, is treated as a strict-priority queue. Traffic for a strict priority
is scheduled before any other queues are serviced. For example, if you send 100%
line rate traffic over the SP queue, it starves all other queues on the ports on which
