Typical Configuration Of CBQ on AR28、AR46 Series Routers

Typical Configuration Of CBQ on AR28、AR46 Series Routers

[Requirements]

Execute classification and cbq for the router.

Classify the packets sent from the internal network.

Classify the packets:

To facilitate the operation and maintenance management, use the following ACL numbers for QoS guaranteeing.

acl n 3181        //Video service

…….

acl n 3182        //Critical service 1

……

acl n 3183        //Critical service 2

…….

acl n 3184        //Critical service 3

……

acl n 3185        //Information website

……….

acl n 3186        //Download service

…………

acl n 3187        //Other services

………….
