API Guide

Usage 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.
Use this command in Configuration Terminal Batch mode to enable the QoS rate adjustment in a dual-homing
setup.

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.
Use this command in Configuration Terminal Batch mode to specify the minimum bandwidth for queues in a dual-
homing setup.
service-class dot1p-mapping
Configure a service-class criterion based on a dot1p value.
C9000 Series
Syntax
service-class dot1p-mapping {dot1p0 value | dot1p1 value | dot1p2 value |
dot1p3 value | dot1p4 value| dot1p5 value | dot1p6 value | dot1p7 value}
