Parameters
Usage Guidelines
Usage Scenario
An ACL6 is a set of rules composed of permit or deny clauses. ACL6s are mainly used in QoS. ACL6s can limit data flows to improve network performance. For example, ACL6s are configured on an enterprise network to limit video data flows, which lowers the network load and improves network performance.
Follow-up Procedure
Run the rule command to configure ACL6 rules and apply the ACL6 to services which packets need to be filtered.
Precautions
- If only the type of a named ACL6 is specified, the number of the named ACL6 allocated by the AC is the maximum value of the named ACL6 of the type.
- If the number and the type of a named ACL6 are not specified, the AC considers the named ACL6 as the advanced ACL6 and allocates the maximum value to the named ACL6.
After you create a named ACL6 by using the acl ipv6 name command, the ACL6 still exists even if you exit from the ACL6 view. You must run the undo acl ipv6 name acl6-name or undo acl ipv6 acl6-number command to delete the ACL6.
When you delete an ACL6 that has been referenced by other services, the services may be interrupted. Therefore, before deleting an ACL6, ensure that the ACL6 is not in use.
