Chapter 18: Quality of Service (QoS) Commands
274 Section I: Basic Features
Description
This command modifies an existing traffic class. To initially create a traffic
class, refer to “CREATE QOS TRAFFICCLASS” on page 253. 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 247.
When modifying a traffic class, note the following:
ˆ You cannot change a traffic class’ ID number.
ˆ 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
