Description
This command is used to create new flow groups.
Note
For examples of the command sequences used to create entire QoS
policies, refer to “CREATE QOS POLICY” on page 356.
Examples
This command creates a flow group with an ID of 10 and a description of
“VoIP flow”. The flow group is assigned a priority level of 7 and defined by
classifiers 15 and 17. In this example, the packets of the flow group leave
the switch with the same priority level as when they entered. The new
priority level is relevant only as the packets traverse the switch. To alter
the packets so that they leave containing the new level, you would include
the REMARKPRIORITY parameter:
create qos flowgroup=10 description=”VoIP flow”
priority=7 classifierlist=15,17
This command creates a similar flow group as in the previous example.
The REMARKPRIORITY parameter is added so that the tagged packets of
the flow group leave the switch with the new priority level of 7:
create qos flowgroup=10 description=”VoIP flow”
priority=7 remarkpriority=yes classifierlist=15,17
This command creates a flow group whose DSCP value is changed to 59.
The MARKVALUE parameter overwrites the current DSCP value in the
packets, meaning the packets leave the switch with the new value. The
classifiers of the flow group are 3, 14, and 24:
create qos flowgroup=10 description=”DSCP 59 flow”
markvalue=59 classifierlist=3,14,24
