Behavior Changes
The following behavior changes will be apparent when using this PVC Routing feature.
1. When the no atm umts command is applied to a base ATM interface, the command will
un-configure the ATM UMTS mode for all the sub-interfaces under that ATM interface.
2. When the no atm umts command is applied to an ATM sub-interface, the command will
