Access Control Lists
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, DSCP traffic class, next header type, 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.
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.
