Chapter 44: Access Control List Commands

Access Control Lists (ACL) provide packet filtering for IPv4 frames (based on
address, protocol, Layer 4 protocol port number or TCP control code), IPv6 frames
(based on address, next header type, or flow label), or any frames (based on MAC
address or Ethernet type). To filter packets, first create an access list, add the
required rules, and then bind the list to a specific port. This section describes the

Access Control List commands.

ACL Information
IPv4 ACLs
The commands in this section configure ACLs based on IPv4 addresses, TCP/UDP
port number, protocol type, and TCP control code. To configure IPv4 ACLs, first
create an access list containing the required permit or deny rules, and then bind the
access list to one or more ports
Command
access-list ip
permit, deny
permit, deny
show ip access-list
ip access-group
show ip access-group
