.SYNOPSIS

Retrieves network interface information for a device from WhatsUp Gold.

.DESCRIPTION

The Get-WUGDeviceInterface function retrieves network interface data using the REST API:

- Get all interfaces: GET /api/v1/devices/{deviceId}/interfaces/-

- Get default interface: GET /api/v1/devices/{deviceId}/interfaces/default

- Get specific interface: GET /api/v1/devices/{deviceId}/interfaces/{interfaceId}

.PARAMETER DeviceId

The ID of the device to retrieve interfaces for. Required.

.PARAMETER InterfaceId

The ID of a specific interface to retrieve. Used with the ByInterfaceId parameter set.

.PARAMETER Default

Switch to retrieve only the default network interface.

.PARAMETER Search

Optional search text to filter interfaces by address or hostname. Case-insensitive.

.PARAMETER Limit

Maximum number of interfaces per page. Valid range: 1-250. Default: 250.

.EXAMPLE

# Get all interfaces for a device

Get-WUGDeviceInterface -DeviceId "123"

.EXAMPLE

# Get the default interface

Get-WUGDeviceInterface -DeviceId "123" -Default

.EXAMPLE

# Get a specific interface by ID

Get-WUGDeviceInterface -DeviceId "123" -InterfaceId "456"

.EXAMPLE

# Search for interfaces

Get-WUGDeviceInterface -DeviceId "123" -Search "192.168"
