Managing Access Control List (ACL) Entries

Access control lists allow you to handle network traffic in a switch by using controlled rule sets. Each ACL rule
is specific to a user-created set of conditions that a data packet must meet to match the rule. In the instance
that a data packet has no ACL rule match, the switch applies the default rule. Otherwise, the switch matches
the data packet to the rule and permits or denies the packet.
You can use ACLs to control host access to different parts of a network or to control traffic forwarding or
blocking at the switch level.
