Access Control Lists
In this chapter
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, or 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.
TABLE 57 Access Control List Commands
Command Group Function
IPv4 ACLs Configures ACLs based on IPv4 addresses, TCP/UDP port number, protocol type,
and TCP control code
IPv6 ACLs Configures ACLs based on IPv6 addresses, DSCP traffic class, or next header type
MAC ACLs Configures ACLs based on hardware addresses, packet format, and Ethernet type
ARP ACLs Configures ACLs based on ARP messages addresses
ACL Information Displays ACLs and associated rules; shows ACLs assigned to each port
