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) priority.  

Using advanced ACLs, you can define classification rules that are more accurate, more abundant, and 

more flexible than those defined for basic ACLs.  

z 

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 

z 

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.  

Follow these steps to define an advanced ACL rule:  

Enter system view  

— 

Create an advanced 
ACL and enter 
advanced ACL view  

acl number acl-number 
[ match-order { auto | config } ] 

Required 

config by default 

Define an ACL rule  

rule [ rule-id ] { permit | deny } 
protocol [ rule-string ] 

Required  

For information about protocol and 
rule-string, refer to ACL Command. 

Assign a description 
string to the ACL rule  

rule rule-id comment text 

Optional  

No description by default 

Assign a description 
string to the ACL 

description text 

Optional  

No description by default 

 

Note that: 

z 

With the config match order specified for the advanced ACL, you can modify any existent rule. The 

unmodified part of the rule remains. With the auto match order specified for the ACL, you cannot 

modify any existent rule; otherwise the system prompts error information.  

z 

If you do not specify the rule-id argument when creating an ACL rule, the rule will be numbered 

automatically. If the ACL has no rules, the rule is numbered 0; otherwise, it is the maximum rule 

number plus one.  

z 

The content of a modified or created rule cannot be identical with the content of any existing rules; 

otherwise the rule modification or creation will fail, and the system prompts that the rule already 

exists.
