From Connection Manager you can configure a WAN interface profile for a device. Configuration changes made to a profile affect all devices currently assigned to that profile. If changes are made to a device configuration that cause it to differ from its assigned profile, then a new profile matching the changes is created with the device automatically assigned to it.
The Edit screen for a WAN interface type only displays features that are configurable for that WAN type. For example, Modem and CDMA tabs do not appear on the configuration screen for Ethernet or WWAN.
Use this document to understand the different WAN interface types and their configuration options.
