watermarks.
To pull (download) dynamic VC weights and watermarks from a RADIUS server, you must enable
dynamic bandwidth selection (DBS) on the VC using the dbs enable command. To remove dynamically
modified VC parameters, enter the no dbs enable command. For more information, see the
Dynamic Bandwidth Selection" section on page
After the router pulls VC weight and watermark parameters from the RADIUS server and successfully
installs or updates the parameters on the VC, any changes to these VC parameters that you configure
using the modular QoS command line interface (MQC) affect only the nvgen values and not the
RADIUS-pulled values.
The VC weight and watermark parameters pulled from the RADIUS server have precedence over the VC
parameters that you configure on the PVC using the MQC. As a result, the show atm vc detail command
displays the dynamically modified VC weight and watermark values pulled from RADIUS; it does not
display the nvgen values configured using CLI commands.

Configuration Commands for Dynamic VC Weight and Watermarks

The dbs enable command is used to configure dynamic VC weight and watermarks. For more
information, see the
The following RADIUS VSAs are used to configure dynamic VC weight and watermarks on the
RADIUS server:
cisco-avpair = "atm:vc-weight=<weight value>"
cisco-avpair = "atm:vc-watermark-min=<minimum watermark value>"
cisco-avpair = "atm:vc-watermark-max=<maximum watermark value>"
Valid VC weight values are from 1 to 255. However, we recommend that you do not configure the value
