Information
By default, when rate policing and shaping, the system does not include the Preamble, SFD, or the IFG
fields. These fields are overhead; only the fields from MAC destination address to the CRC are used for
forwarding and are included in these rate metering calculations.

Specify a minimum bandwidth for queues.
Syntax

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.
service-class dot1p-mapping
Configure a service-class criterion based on a dot1p value.
Syntax
service-class dot1p-mapping {dot1p0 queue | dot1p1 queue | dot1p2 queue |
dot1p3 queue | dot1p4 queue| dot1p5 queue | dot1p6 queue | dot1p7 queue}
Parameters
queue Enter a value from 0 to 7.
Defaults For each dot1p Priority, the default CoS queue value is:
● Dot1p Priority : 0 1 2 3 4 5 6 7
● Queue : 1 0 2 3 4 5 6 7
