Subscriber Services: DHCP rate adjustment

You can use DHCP tags to modify the CLI-configured and RADIUS-configured shaping rate values after a subscriber is instantiated. The new values are conveyed in DHCP option 82, suboption 9 discovery packets. Suboption 9 contains the Internet Assigned Numbers Authority (IANA) DSL Forum VSA (vendor ID 3561). Configure the shaping rate adjustment controls by including the dhcp-tags statement at the [edit class-of-service adjustment-control-profiles profile-name application] hierarchy level. Specify the desired rate-adjustment algorithm and set a priority for the DHCP Tags application in the adjustment control profile.
