Configuration procedure
# Create advanced ACL 3000, and configure a rule to match packets whose source port number is
not 21.
<Router> system-view
[Router] acl number 3000
[Router-acl-adv-3000] rule 0 permit tcp source-port neq 21
[Router-acl-adv-3000] quit
# Create a class named classifier_1, and use ACL 3000 as the match criterion in the class.
[Router] traffic classifier classifier_1
[Router-classifier-classifier_1] if-match acl 3000
[Router-classifier-classifier_1] quit
# Create a behavior named behavior_1, and configure the traffic filtering action to drop packets.
[Router] traffic behavior behavior_1
[Router-behavior-behavior_1] filter deny
[Router-behavior-behavior_1] quit
# Create a policy named policy, and associate class classifier_1 with behavior behavior_1 in the
policy.

[Router-qospolicy-policy] quit
# Apply the policy named policy to the incoming traffic of GigabitEthernet 1/0/1.
