Command History
Version Description
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 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queues are superseded by ETS congurations.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
0 0-7
1 0-7
