Configuring ACLs
NOTE:
The IPv6 ACL configuration is available only at the CLI.
Overview
An access control list (ACL) is a set of rules (or permit or deny statements) for identifying traffic based on
criteria such as source IP address, destination IP address, and port number.
You can use ACLs in QoS, firewall, routing, and other technologies for identifying traffic. The packet drop
or forwarding decisions varies with modules that use ACLs. See the specific module for information about
ACL application.
ACL categories
Category ACL number IP version Match criteria
Basic ACLs 2000 to 2999
IPv4 Source IPv4 address
IPv6 Source IPv6 address
Advanced ACLs 3000 to 3999
IPv4
Source IPv4 address, destination IPv4 address,
packet priority, protocols over IPv4, and other
Layer 3 and Layer 4 header fields
IPv6
Source IPv6 address, destination IPv6 address,
packet priority, protocols over IPv6, and other
Layer 3 and Layer 4 header fields
Ethernet frame
header ACLs
4000 to 4999 IPv4 and IPv6
Layer 2 header fields, such as source and
destination MAC addresses, 802.1p priority,
and link layer protocol type
ACL numbering and naming
Each ACL category has a unique range of ACL numbers. When creating an ACL, you must assign it a
number for identification. In addition, you can assign the ACL a name for the ease of identification. After
creating an ACL with a name, you cannot rename it or delete its name.
For an Ethernet frame header ACL, the ACL number and name must be globally unique. For an IPv4 basic
or advanced ACLs, its ACL number and name must be unique among all IPv4 ACLs, and for an IPv6
basic or advanced ACL, among all IPv6 ACLs. You can assign an IPv4 ACL the same number and name
as an IPv6 ACL.
