DELETE QOS FLOWGROUP
Syntax
delete qos flowgroup= value classifierlist= values
Parameter
flowgroup Specifies the ID number of the flow group you want to
modify. You can modify only one flow group at a time.
classifierlist Specifies the classifiers you want to remove from the flow
group. Separate multiple classifiers 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 classifiers. Since the purpose
of this command is to remove classifiers from flow groups,
you are unlikely ever to use that option.)
Description
This command removes classifiers from flow groups.
Example
This command removes classifier 6 from flow group 22:
delete qos flowgroup=22 classifierlist=6
