Configuring Initial CoS Parameters Dynamically Obtained from RADIUS

You can configure a subscriber interface so that subscribers receive initial CoS parameters that the router obtains from the RADIUS authentication server when subscribers log in using that logical interface on the router.

1. Configure external RADIUS server VSAs with values that you expect subscribers to log in with.
   • To configure a RADIUS authentication server to include CoS traffic-shaping parameters in authentication grants on certain subscriber interfaces, configure Juniper Networks VSA 26–108.
   • To configure a RADIUS authentication server to include CoS scheduling and queuing parameters in authentication grants a certain subscriber interfaces, configure Juniper Networks VSA 28–146.

   See Configuring Router or Switch Interaction with RADIUS Servers and Configuring RADIUS Server Parameters for Subscriber Access.

2. Configure a subscriber interface that supports hierarchical CoS.
   • For static VLAN interfaces, see Configuring Static Subscriber Interfaces in Dynamic Profiles.
   • For static VLAN interfaces over aggregated Ethernet, see Configuring a Static or Dynamic VLAN Subscriber Interface over Aggregated Ethernet.
   • For static IP demux interface sets, see Configuring Dynamic Subscriber Interfaces Using IP Demux Interfaces in Dynamic Profiles.
   • For dynamic IP demux interface sets, see Configuring a Subscriber Interface Using a Set of Static IP Demux Interfaces
3. Associate a traffic control profile with the interface.

   See Applying Traffic Shaping and Scheduling to a Subscriber Interface in a Dynamic Profile.

4. Configuring initial traffic-shaping parameters to be obtained from RADIUS.

   See Configuring Dynamic Traffic Shaping and Scheduling Parameters in a Dynamic Profile.

5. Configure forwarding classes and scheduler maps statically.

   See Configuring Forwarding Classes and Configuring Scheduler Maps.

6. Configure a scheduler to specify initial scheduling and queuing parameters to be dynamically obtained from RADIUS when a subscriber logs in.
