Usage Scenario

Before running this command, you need to run the acl command and the rule command to configure the ACL.
Only the ACL of the same type can be configured without conflict on a user interface, namely, IPv4 inbound, IPv4 outbound, IPv6 inbound, and IPv6 outbound. Only one ACL can be configured for each type.
After the configurations of this ACL take effect, all users in the user interface are under the restriction of this ACL.

Precautions

If no ACL rule is configured, running the acl command does not restrict the outgoing calls of user interfaces.
