Configuring an Interface-based ACL6 Rule

Procedure

1. Run system-view

   The system view is displayed.

2. Run acl ipv6 { name interface-based-acl6-name interface | number interface-based-acl6-number } [ match-order { config | auto } ]

   The interface-based ACL6 view is displayed.

3. Run rule [ rule-id ] [ name rule-name ] { deny | permit } interface { interface-type interface-number | any } [ time-range time-name ] ^*

   A rule is configured for the interface-based ACL6.

   • Adding new rules to an ACL6 will not affect the existing rules.

   • When an existing rule is edited and the edited contents conflict with the original contents, the edited contents take effect.

   

   When you configure an interface-based ACL6:

   • If an interface is specified by configuring interface, the system filters only packets received by this specified interface.

   • If all interfaces are specified by configuring any, the system does not check packets' inbound interfaces, and considers that all packets have matched the rule and directly takes an action (deny or permit) on the packets.

   • If a validity period is specified by configuring time-range, the time range name specified by time-name must already exist. Otherwise, the configuration does not take effect.

4. (Optional) Run rule rule-id description destext

   The description for an ACL6 rule is configured.

   The description of an ACL6 rule can contain the functions of the ACL6 rule. Configuring a description for an ACL6 rule is recommended to prevent misuse of the rule in the following situations:

   • A large number of ACL6s are configured, and their functions are difficult to identify.
   • An ACL6 is used at a long interval, and its function may be left forgotten.

5. Run commit

   The configuration is committed.
