Feature Limitations

  • When permit and other actions are configured in a traffic behavior, the actions are performed in sequence. deny cannot be configured with other actions except traffic statistics and flow mirroring. When deny is used, the only configured actions that take effect are traffic statistics and flow mirroring.
  • The action taken for packets matching an Active Control List (ACL) rule depends on the permit and deny configuration in the traffic behavior if the packets match an ACL rule that defines permit. However, packets are discarded regardless of traffic behavior configuration if they match an ACL rule that defines deny.
