Configuration procedure
# Create advanced ACL 3000, and configure a rule to match packets whose source port number is 21.
<DeviceA> system-view
[DeviceA] acl number 3000
[DeviceA-acl-basic-3000] rule 0 permit tcp source-port eq 21
[DeviceA-acl-basic-3000] quit
# Create a class named classifier_1, and reference ACL 3000 in the class.
[DeviceA] traffic classifier classifier_1
[DeviceA-classifier-classifier_1] if-match acl 3000
[DeviceA-classifier-classifier_1] quit
