Configuring Dynamic Bandwidth Selection

Dynamic bandwidth selection enables you to dynamically change ATM QoS traffic shaping parameters
based on RADIUS user or domain profiles (see the
RADIUS Profiles" section on page
To configure dynamic bandwidth selection, perform the following required configuration tasks:

Configuring the Router for Dynamic Bandwidth Selection

To configure the router for dynamic bandwidth selection, perform any of the following configuration
tasks:

Enabling Dynamic Bandwidth Selection on a VC Class
To enable dynamic bandwidth selection on a VC class, enter the following commands beginning in
global configuration mode:
Command
Step 1
Router(config)# vc-class atm name
Step 2
Router(config-vc-class)# dbs enable
Configuration Example for Enabling Dynamic Bandwidth Selection on a VC Class
Example 17-1
dynamic bandwidth selection is enabled on a VC class named cisco.
Example 17-1 Enabling Dynamic Bandwidth Selection on a VC Class
Router(config)# vc-class atm cisco
Router(config-vc-class)# dbs enable
OL-7433-09
DBS does not support constant bit rate (CBR) PVCs. The Cisco 10000 series router supports only
UBR and variable bit rate (VBR) PVCs for DBS.
DBS is supported only on VBR-nrt VCs under virtual path (VP) tunnels in pxf queuing mode.

Purpose
Configures a VC class for an ATM VC or interface. Enters VC
class configuration mode.
name is the name of the VC class.
Enables dynamic bandwidth selection and allows the traffic
shaping parameters retrieved from RADIUS to be applied to the
VC class.
