ACL 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.
ACLs are essentially used for packet filtering. A packet filter drops packets that match a deny rule and
permits packets that match a permit rule. ACLs are also widely used by many modules, for example,
QoS and IP routing, for traffic identification.
This section covers these topics:

z Implementing Time-Based ACL Rules
z IPv4 Fragments Filtering with ACLs
ACL Categories
ACLs fall into four categories, as shown in Table 4-1.
Table 4-1 ACL categories
Category ACL number IP version Match criteria
WLAN ACLs 100 to 199 IPv4 Wireless client SSID
IPv4 Source IPv4 address
Basic ACLs 2000 to 2999
IPv6 Source IPv6 address
IPv4
Source/destination IPv4 address, protocols over
IPv4, and other Layer 3 and Layer 4 header fields
Advanced ACLs 3000 to 3999
IPv6
Source/destination IPv6 address, protocols over
IPv6, and other Layer 3 and Layer 4 header fields
Ethernet frame
header ACLs
4000 to 4999 IPv4
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, and in addition, you can also assign the ACL a name for the ease of
identification. After creating an ACL with a name, you can neither rename it nor delete its name.
You cannot assign a name for a WLAN ACL.
For a WLAN and Ethernet frame header, 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.
Match Order
The rules in an ACL are sorted in certain order. When a packet matches a rule, the device stops the
match process and performs the action defined in the rule. If an ACL contains overlapping or conflicting
rules, the matching result and action to take depend on the rule order.
Two ACL match orders are available:
z config – Sorts ACL rules in ascending order of rule ID. A rule with a lower ID is matched before a
rule with a higher ID. If you use this approach, check rule content and order carefully.
4-3
z auto – Sorts ACL rules in depth-first order. Depth-first ordering ensures that any subset of a rule is
always matched before the rule.
Table 4-2 lists the sequence of tie breakers that depth-first
ordering uses to sort rules for each type of ACL.
The match order of WLAN ACLs can only be config.
Table 4-2 Sort ACL rules in depth-first order
ACL category Sequence of tie breaker
IPv4 basic ACL
1) VPN instance
2) More 0s in the source IP address wildcard (more 0s means a narrower IP address
range)
3) Smaller rule ID
IPv4 advanced ACL
1) VPN instance
2) Specific protocol type rather than IP (IP represents any protocol over IP)
3) More 0s in the source IP address wildcard mask
4) More 0s in the destination IP address wildcard
5) Narrower TCP/UDP service port number range
6) Smaller ID
IPv6 basic ACL
1) Longer prefix for the source IP address (a longer prefix means a narrower IP
address range)
2) Smaller ID
IPv6 advanced ACL
1) Specific protocol type rather than IP (IP represents any protocol over IPv6)
2) Longer prefix for the source IPv6 address
3) Longer prefix for the destination IPv6 address
4) Narrower TCP/UDP service port number range
5) Smaller ID
Ethernet frame
header ACL
1) More 1s in the source MAC address mask (more 1s means a smaller MAC
address)
2) More 1s in the destination MAC address mask
3) Smaller ID
z The AP does not support ACL rules with the VPN instance attribute.
z A wildcard mask, also called an inverse mask, is a 32-bit binary and represented in dotted decimal
notation. In contrast to a network mask, the 0 bits in a wildcard mask represent 'do care' bits, while
the 1 bits represent 'don’t care bits'. If the 'do care' bits in an IP address identical to the 'do care' bits
in an IP address criterion, the IP address matches the criterion. All 'don’t care' bits are ignored. The
0s and 1s in a wildcard mask can be noncontiguous. For example, 0.255.0.255 is a valid wildcard
mask.
4-4
ACL Rule Numbering
What is the ACL rule numbering step
If you do not assign an ID for the rule you are creating, the system automatically assigns it a rule ID. The
rule numbering step sets the increment by which the system automatically numbers rules. For example,
the default ACL rule numbering step is 5. If you do not assign IDs to rules you are creating, they are
numbered 0, 5, 10, 15, and so on. The wider the numbering step, the more rules you can insert between
two rules.
By introducing a gap between rules rather than contiguously numbering rules, you have the flexibility of
inserting rules in an ACL. This feature is important for a config order ACL, where ACL rules are matched
in ascending order of rule ID.
Automatic rule numbering and re-numbering
The ID automatically assigned to an ACL rule takes the nearest higher multiple of the numbering step to
the current highest rule ID, starting with 0.
For example, if the numbering step is 5 (the default), and there are five ACL rules numbered 0, 5, 9, 10,
and 12, the newly defined rule will be numbered 15. If the ACL does not contain any rule, the first rule
will be numbered 0.
Whenever the step changes, the rules are renumbered, starting from 0. For example, if there are five
rules numbered 5, 10, 13, 15, and 20, changing the step from 5 to 2 causes the rules to be renumbered
0, 2, 4, 6 and 8.
Implementing Time-Based ACL Rules
You can implement ACL rules based on the time of day by applying a time range to them. A time-based
ACL rule takes effect only in any time periods specified by the time range.
Two basic types of time range are available:
z Periodic time range, which recurs periodically on a day or days of the week.
z Absolute time range, which represents only a period of time and does not recur.
You may apply a time range to ACL rules before or after you create it. However, the rules using the time
range can take effect only after you define the time range.
IPv4 Fragments Filtering with ACLs
Traditional packet filtering matches only first fragments of IPv4 packets, and allows all subsequent
non-first fragments to pass through. Attackers can fabricate non-first fragments to attack networks.
To avoids the risks, the H3C ACL implementation:
z Filters all fragments by default, including non-first fragments.
z Provides standard and exact match modes for matching ACLs that contain advanced attributes
such as TCP/UDP port number and ICMP type. Standard match is the default mode. It considers
only Layer 3 attributes. Exact match considers all header attributes defined in IPv4 ACL rules.

Configuring an Advanced ACL
Configuring an IPv4 advanced ACL
IPv4 advanced ACLs match packets based on source and destination IP addresses, protocols over IP,
and other protocol header information, such as TCP/UDP source and destination port numbers, TCP
flags, ICMP message types, and ICMP message codes.
IPv4 advanced ACLs also allow you to filter packets based on three priority criteria: type of service (ToS),
IP precedence, and differentiated services codepoint (DSCP) priority.
Compared with IPv4 basic ACLs, IPv4 advanced ACLs allow of more flexible and accurate filtering.
Follow these steps to configure an IPv4 advanced ACL:
To do… Use the command… Remarks
Enter system view

Configuring an IPv6 Advanced ACL
IPv6 advanced ACLs match packets based on the source IPv6 address, destination IPv6 address,
protocol carried over IPv6, and other protocol header fields such as the TCP/UDP source port number,
TCP/UDP destination port number, ICMP message type, and ICMP message code.
Compared with IPv6 basic ACLs, they allow of more flexible and accurate filtering.
