### IP Interface and Addresses

Follow these general guidelines:

- Define the IP interfaces for each CLAN and Media processor circuit pack on the switch that uses the IP Interfaces screen. For more information, see Administration for Network Connectivity for Avaya Communication Manager (Document 555-233-504).
- On the Customer Options form, verify that the IP Stations field is set to “y” (Yes). If it is not, contact your Avaya sales representative. The IP Softphone field does not have to be set to “y” (Yes).
