The configuration allows a wired or wireless network interface controller to pass all traffic it receives to the Central Processing Unit (CPU), rather than passing only the frames that the controller

Multicast mode involves sending data packets to a group of destination computers simultaneously.

Promiscuous mode is a setting for a network interface controller (NIC) that allows it to capture and pass all network traffic it sees on a network segment to the operating system's CPU, even if the traffic is not addressed to the NIC's MAC address. This mode is commonly used by network analyzers and sniffers to monitor all traffic.

WEM (Workload Environment Manager) is typically a management tool for virtual desktop environments and not a network interface mode.

Port forwarding redirects traffic from one network port to another, often across a NAT device.
