General steps for implementing ACLs

Procedure
  1. Configure one or more ACLs.
  2. This creates and stores the ACL(s) in the switch configuration.
  3. Assign an ACL.
  4. This step uses one of the following applications to assign the ACL to an interface:
    1. VACL (any IPv4 traffic entering the switch on a given VLAN)
    2. Static Port ACL (any IPv4 traffic entering the switch on a given port, port list, or static trunk)
