Defaults none
Command Modes CONFIGURATION
Command History
Version 9.0(1.3) Introduced on the S5000.
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 this traffic is flowing.
Policy-Based QoS Commands
Policy-based traffic classification is handled with class maps. These maps classify unicast traffic into one of four
classes on the S5000. FTOS 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.
S5000

Parameters

Enter the percentage assignment of weight to the class/queue. The
range is 0 to 100% (granularity 1%).
Defaults none
Command Modes CONFIGURATION (conf-qos-policy-out)
Command History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
The unit of bandwidth percentage is 1%. A bandwidth percentage of 0 is allowed and disables
the scheduling of that class. If the sum of the bandwidth percentages given to all eight classes
exceeds 100%, the bandwidth percentage automatically scales down to 100%.
