Configuration example
# Configure ACL 2000 to deny packets whose source IP addresses are 192.168.0.1.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule deny source 192.168.0.1 0
# Display the configuration information of ACL 2000.
[Sysname-acl-basic-2000] display acl 2000
Basic ACL
Acl's step is 1
rule 0 deny source 192.168.0.1 0

Configuring Advanced ACL

An advanced ACL can filter packets by their source and destination IP addresses, the
protocols carried by IP, and protocol-specific features such as TCP/UDP source and
destination ports, ICMP message type and message code.
An advanced ACL can be numbered from 3000 to 3999. Note that ACL 3998 and ACL 3999
cannot be configured because they are reserved for cluster management.
Advanced ACLs support analysis and processing of three packet priority levels: type of
service (ToS) priority, IP priority and differentiated services codepoint (DSCP).
Using advanced ACLs, you can define classification rules that are more accurate, more
abundant, and more flexible than those defined for basic ACLs.
Configuration prerequisites
To configure a time range-based advanced ACL rule, you need to create the
corresponding time ranges first. For information about of time range configuration,
refer to Configuring Time
The settings to be specified in the rule, such as source and destination IP addresses,
the protocols carried by IP, and protocol-specific features, are determined.
