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-weight command from CONFIGURATION mode. The
command is applied in the same way as the
bandwidth-weight command in an
output QoS policy. The bandwidth-weight command in QOS-POLICY-OUT
mode supersedes the
service-class bandwidth-weight 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the default bandwidth allocation ratio for egress queues are superseded by ETS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 recommends disabling ETS when you wish to apply these features
exclusively. After you disable ETS on an interface, the configured parameters are
applied.
Policy-Based QoS Commands
Policy-based traffic classification is handled with class maps. These maps classify unicast traffic into one
of four classes. The system allows you to match multiple class maps and specify multiple match criteria.
Policy-based QoS is not supported on logical interfaces, such as port-channels, VLANs, or Loopbacks.
bandwidth-percentage
Assign a percentage of weight to the class/queue.
Syntax
bandwidth-percentage percentage
To remove the bandwidth percentage, use the no bandwidth-percentage
command.
Parameters
percentage Enter the percentage assignment of weight to the class/
queue. The range is from 0 to 100% (granularity 1%).
