# Define ACL 2000 and specify “depth-first” as the match order.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] acl number 2000 match-order auto
[Sysname-acl-basic-2000]
# Add three rules with different numbers of zeros in the source wildcards.
[Sysname-acl-basic-2000] rule 1 permit source 1.1.1.1 0.255.255.255
[Sysname-acl-basic-2000] rule 2 permit source 2.2.2.2 0.0.255.255
[Sysname-acl-basic-2000] rule 3 permit source 3.3.3.3 0.0.0.255
# Use the
display acl
command to display the configuration information of ACL 2000.
[Sysname-acl-basic-2000] display acl 2000
Basic ACL 2000, 3 rules, match-order is auto
Acl's step is 1
rule 3 permit source 3.3.3.0 0.0.0.255
rule 2 permit source 2.2.0.0 0.0.255.255
rule 1 permit source 1.0.0.0 0.255.255.255
As shown in the output information, the switch sorts the rules of ACL 2000 in the depth-first order: a rule
with more zeros in the source IP address wildcard has a higher priority.
