By configuring UCL-based traffic policies, you can distinguish between users of different priorities and implement QoS on the traffic of users. In this manner, the CIR and PIR are guaranteed for users.
UCL implements user-specific ACL control. During user authentication, to control traffic of some users, for example, to allow or restrict users' access to specific web pages, configure UCL-based traffic policies.
UCL rules can be used for IPv4 and IPv6 traffic classification. For IPv6 traffic classification, UCL rules apply only to upstream traffic.
Before configuring UCL-based traffic policies, complete the following tasks:
Configuring link layer protocol parameters (and IP addresses) for interfaces to ensure that the link layer protocol on the interfaces is Up
Configuring a routing protocol on the backbone network to realize the IP interworking
Configuring the access services to enable the users to access the Internet normally
