Issue/Introduction

How to fetch router devices and list specific WAN interfaces using the command line?

Resolution

There is no single command to retrieve interface names and their types (e.g., WAN) in one step. To achieve this, you must first list the interfaces for a specific device and then query each interface for its "Type" property.

Use the following command to see all interfaces associated with a device name or IP address:

./dmctl -s INCHARGE-AM-PM getl Interface | grep <Device_Name_or_IP>

Once you have the specific interface name (e.g., IF-Name), run this command to determine if it is a WAN interface:

./dmctl -s INCHARGE-AM-PM get Interface::<IF-Name> | grep Type
