Configuration Commands for DBS
This section describes the following commands used to configure dynamic bandwidth selection (DBS):

dbs enable Command
To enable dynamic bandwidth selection QoS and apply the traffic shaping parameters retrieved from
RADIUS to the ATM virtual circuit (VC) class, ATM VC, ATM PVC range, or ATM PVC within a PVC
range, use the dbs enable command in the appropriate configuration mode. To disable dynamic
bandwidth selection, use the no form of the command. By default, DBS is disabled.

Usage Guidelines for the dbs enable Command
When changing ATM QoS values dynamically on a VC, the connection might be disrupted for a short
duration (typically milliseconds).
The no dbs enable command configured in any configuration mode (for example, PVC) overrides the
dbs enable command configured in any configuration mode (for example, VC class). For more
information, see the
Both the dbs enable and no dbs enable commands are nvgenned, that is, they are saved in the running
configuration and appear, when configured, in the output of the show running-config command. If you
use the default setting of DBS (no dbs enable) without explicitly configuring it, the no dbs enable
command does not appear in the show running-config output.
