Chapter 20: Quality of Service (QoS) Commands
340
flowgrouplist Specifies the flow groups to be assigned to the
traffic class. Any flow groups already assigned to
the traffic class are replaced. The specified flow
groups must already exist. Separate multiple IDs
with commas (e.g., 4,11,13).
Description
This command modifies an existing traffic class. To initially create a
traffic class, refer to CREATE QOS TRAFFICCLASS on page 320. The only
parameter you cannot change is a traffic classes ID number.
Note
For examples of command sequences used to create entire QoS
policies, refer to CREATE QOS POLICY on page 314.
When modifying a traffic class, note the following:
❑You cannot change a traffic class’ ID number.
❑Specifying an invalid value for a parameter that already has a
value causes the parameter to revert to its default value.
Examples
This command changes the exceed action in traffic class 18 to remark
and specifies a remark value of 24. This command changes the DSCP
value in traffic that exceeds the maximum bandwidth to 24:
set qos trafficclass=18 exceedaction=remark
exceedremarkvalue=24
This command changes the user priority value to 17 for traffic belonging
to traffic class 42:
set qos trafficclass=42 priority=17
This command changes the maximum bandwidth for traffic class 41 to
80 Mbps and the burst size to 400 Kbps.
set qos trafficclass=41 maxbandwidth=80
burstsize=400
