qos-group dscp
Configures a DSCP trust map to the traffic class.
Syntax
qos-group tc-list [dscp values]
Parameters
● qos-group tc-list — Enter the traffic single value class ID, from 0 to 7.
● dscp values — (Optional) Enter either single, comma-delimited, or a hyphenated range of DSCP
values, from 0 to 63.
Default 0
Command Mode TRUST-MAP
Usage
Information
If the trust map does not define DSCP values to any traffic class, those flows map to the default traffic
class 0. If some of the DSCP values are already mapped to an existing traffic class, you will see an error.
The no version of this command returns the value to the default.
Example
OS10(conf-tmap-dscp-qos)# qos-group 5 dscp 42
