Access Control List Commands
Access Control Lists (ACL) provide packet filtering for IP frames (based on address,
protocol, or 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.
IP ACLs
The commands in this section configure ACLs based on IP addresses, TCP/UDP port
number, protocol type, and TCP control code. To configure IP ACLs, first create an
access list containing the required permit or deny rules, and then bind the access list to
one or more ports.
