Usage Guidelines
No IPv4 ACLs are defined by default.
Use IPv4 ACLs to filter IPv4 traffic.
When you use the
ip access-list
command, the device enters IP access list configuration mode, where you
can use the IPv4
deny
and
permit
commands to configure rules for the ACL. If the ACL specified does not
exist, the device creates it when you enter this command.
Use the
ip access-group
command to apply the ACL to an interface as a router ACL. Use the
ip port
access-group
command to apply the ACL to an interface as a port ACL.
Every IPv4 ACL has the following implicit rule as its last rule:
deny ip any any
This implicit rule ensures that the device denies unmatched IP traffic.
Unlike IPv6 ACLs, IPv4 ACLs do not include additional implicit rules to enable the neighbor discovery
process. The Address Resolution Protocol (ARP), which is the IPv4 equivalent of the IPv6 neighbor discovery
process, uses a separate data link layer protocol. By default, IPv4 ACLs implicitly allow ARP packets to be
sent and received on an interface.
Use the
statistics per-entry
command to configure the device to record statistics for each rule in an IPv4
ACL. The device does not record statistics for implicit rules. To record statistics for packets that would match
the implicit
deny ip any any
rule, you must explicitly configure an identical rule.
This command does not require a license.
