Chapter 1 ACL Configuration

Huawei Technologies Proprietary

1-3

Note:

The depth-first principle is to put the statement specifying the smallest range of packets

on the top of the list. This can be implemented through comparing the wildcards of the

addresses. The smaller the wildcard is, the less hosts it can specify. For example,

129.102.1.1 0.0.0.0 specifies a host, while 129.102.1.1 0.0.255.255 specifies a network

segment, 129.102.0.1 through 129.102.255.255. Obviously, the former one is listed

ahead in the access control list.

The specific standard is as follows.

For basic access control list statements, comparing the source address wildcards

directly. If the wildcards are same, follow the configuration sequence.

For the access control list based on the interface filter, the rule that is configured with

any

is listed in the end, while others follow the configuration sequence.

For the advanced access control list, comparing the source address wildcards first. If

they are the same, then comparing the destination address wildcards. For the same

destination address wildcards, comparing the ranges of port number, the one with

smaller range is listed ahead. If the port numbers are in the same range, follow the

configuration sequence.

1.1.2 ACL Supported by the Ethernet Switch

For Ethernet Switch, ACLs are divided into the following categories:

Numbered basic ACL.

Named basic ACL.

Numbered advanced ACL.

Named advanced ACL.

Numbered Layer-2 ACL.

Named Layer-2 ACL.

Numbered user-defined ACL.

Named user-defined ACL.

The table below lists the limits to the numbers of different ACL on a switch.
