Access Control Lists (ACL) provide packet filtering for IPv4 frames (based

on address, protocol, Layer 4 protocol port number or TCP control code), 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.

S

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.
