DELETE QOS TRAFFICCLASS
Syntax
delete qos trafficclass=integer
flowgrouplist=integers
Parameter
flowgroup Specifies the ID number of the traffic class you want
to modify. You can modify only one traffic class at a
time.
flowgrouplist Specifies the IDs of the flow groups you want to
remove from the traffic class. Separate multiple flow
groups with commas (e.g., 4,11,12). (The online help
for this command includes a NONE option for this
parameter. Specifying the NONE option does not
remove any flow groups. Since the purpose of this
command is to remove flow groups from a traffic
class, it is unlikely you would ever use that option.)
Description
This command removes flow groups from traffic classes.
Example
This command removes flow group 5 from traffic class 22:
delete qos trafficclass=22 flowgrouplist=5
