the protected data flows and apply the ACL to a security policy.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
acl [ number ] acl-number [ match-order { config | auto } ]
An advanced ACL is created and the ACL view is displayed.
Step 3 Run:
rule
An ACL rule is configured.
NOTE
l The ACL must be configured to match the data flows accurately. It is recommended that you set the
action of the ACL rule to permit for the data flows that need to be protected.
l Create different ACLs and IPSec policies for the data flows with different security requirements.
