IPv4 Access Control Lists (ACLs)
Introduction
Notes IPv4 ACLs can enhance network security by blocking selected traffic, and can
serve as part of your network security program. However, because ACLs do
not provide user or device authentication, or protection from malicious
manipulation of data carried in IPv4 packet transmissions, they should not
be relied upon for a complete security solution.
IPv4 ACLs on the switches covered by this manual do not filter non-IPv4 traffic
such as IPv6, AppleTalk, and IPX packets.
