CLEAR-Flow is an extension to ACLs, so you must be familiar with configuring ACLs before you add CLEAR-Flow rules to your ACL policies. Creating ACLs is described in detail in the ACLs chapter. The chapter describes how to create ACL policies, the syntax of an ACL policy file, and how to apply ACL policies to the switch.
In this chapter, you will find information about the CLEAR-Flow rules that you add to ACL policies, including the CLEAR-Flow rules' syntax and behavior.
After creating the ACLs that contain CLEAR-Flow rules, and after applying the ACLs to the appropriate interface, you enable CLEAR-Flow on the switch. When CLEAR-Flow is enabled, the agent on the switch evaluates the rules, and when any rules are triggered, the CLEAR-Flow actions are executed.
NoteAny actions triggered while CLEAR-Flow is enabled will continue when CLEAR-Flow is disabled, unless explicitly stopped.
