Chapter 18: Quality of Service (QoS) Commands
246 Section I: Basic Features
yes, on, true Replaces the user priority value in the
packets with the new value specified
with the PRIORITY parameter.
no, off, false Does not replace the user priority value
in the packets with the new value
specified in with the PRIORITY
parameter. This is the default.
classifierlist Specifies the classifiers to be assigned to the flow
group. Separate multiple classifiers with commas (e.g.,
4,7,8). The classifiers must already exist.
Description
This command creates a new flow group.
Note
For examples of command sequences used to create entire QoS
policies, refer to “CREATE QOS POLICY” on page 247.
Examples
This command creates a flow group with an ID of 10 and the description
“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
