ACL

The following sections describe how to view, add, modify, delete ACLs and ACL effective period, and configure the ACL function. The S2700SI switches do not support the ACL function.

The access control list (ACL) is used to identify flows. A network device filters packets according to certain rules. It must identify packets first, and then permits or denies the packets according to the policy that you have configured.

• Effective Period
  By configuring the effective period, you can apply an ACL to packets in a certain period of time.
• ACL
  An ACL classifies packets according to matching rules. The rules can be source addresses, destination addresses, or the port numbers of the packets.
