Usage Information When you apply rate-shape in QoS policy both on the Queue Level and in Aggregate mode, the queue-
based shaping occurs rst then aggregate rate shaping.
service-class bandwidth-percentage
Specify a minimum bandwidth for queues.
Syntax
service-class bandwidth-percentage queue0 number queue1 number queue2
number queue3 number
Parameters
number Enter the bandwidth-weight, as a percentage. The range is from 1 to 100.
Defaults none
Command Modes CONFIGURATION
Supported Modes Programmable-Mux (PMUX)
Command History
Version Description
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 dierent 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egress queues are superseded by ETS congurations. 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 congured parameters are applied.
service-class dot1p-mapping
Congure a service-class criterion based on a dot1p value.
Syntax
service-class dot1p-mapping {dot1p0 value | dot1p1 value | dot1p2 queue |
dot1p3 value | dot1p4 value| dot1p5 value | dot1p6 value | dot1p7 value}
Parameters
value Enter a dot1p list number and value. The list number range is from 0 to 7. The range
is from 0 to 3.
Defaults For each dot1p Priority, the default CoS queue value is:
• dot1p CoS Queue
