Description
Use this command to create a classifier. The classifier defines criteria in
order to filter traffic. Classifiers are assigned to a flow group.
Here are the guidelines for creating a flow group:
 You cannot use the iptos and ipdscp parameters at the same time.
 When the tcpsport and tcpdport parameters are specified, you
cannot use the udpsport and udpdport parameters.
 When the iptos, ipdscp, ipprotocol, ipdaddr, or ipsaddr parameter
is specified, the protocol parameter is automatically set to ip.
Confirmation Command
“SHOW CLASSIFIER” on page 489
Example
The following command creates classifier 10:
Manager > create classifier=10 ipdaddr=192.168.10.0/24
