Configuring ATM > Creating an ATM Subinterface

Creating an ATM Subinterface

You can create an ATM subinterface from the interface or from a VP tunnel.

NOTE: Although these steps describe creating an ATM subinterface on an ATM interface, they can be used to create subinterfaces on a VP tunnel.

To create an ATM subinterface:

1. Navigate to the ATM interface in the list area.
2. Select a subinterface, right-click, select Create, and click ATM Sub Interface.

The Create ATM Sub Interface dialog box appears.

3. Set the ATM subinterface parameters (Table 56).
   

   NOTE: For information about dynamic interfaces, see NMC-RX User Guide, Vol. 2, Chapter 7, Configuring Profiles.
