example, dynamic bandwidth selection (DBS) is enabled on PVC 60 in the PVC range named cisco
(PVC 0/50 to PVC 0/70).

Configuring RADIUS Profiles for Dynamic Bandwidth Selection

To configure RADIUS profiles for dynamic bandwidth selection, configure the dynamic bandwidth
selection (DBS) QoS parameters in the domain service profiles or the user profiles on the authentication,
authorization, and accounting AAA server (such as RADIUS). If you apply the QoS parameters in a
domain service profile, all users that connect to that domain are assigned the same QoS parameters. If
you apply the QoS parameters in a user profile, the locally terminated session for that user is assigned
the QoS parameters. The Cisco 10000 series router downloads the user or domain profile from the
RADIUS server as part of user authentication.
The QoS management string for dynamic bandwidth selection has the following syntax:
Cisco-Avpair = atm:peak-cell-rate=155000
Cisco-Avpair = atm:sustainable-cell-rate=155000
You must configure the peak cell rate (PCR) parameter and you can optionally configure the sustained
cell rate (SCR) parameter. The following configuration rules apply:

If you configure only PCR, the ATM service type is unspecified bit rate (UBR).
If you specify both SCR and PCR, the ATM service type is variable bit rate-nonreal-time (VBR-nrt).
If the PCR value is greater than the maximum rate allowed on the ATM physical interface, the PCR
value applied on the VC is the maximum rate allowed on the interface.
If the PCR value is less than the minimum rate allowed on the physical interface, the PCR value
applied on the VC is the minimum rate allowed on the interface.
If the SCR value exceeds the maximum for the interface, the session is rejected.
