promiscuous mode

In an Ethernet local area network ( LAN), promiscuous mode is a mode of operation in which every data packet transmitted can be received and read by a network adapter.
What is promiscuous mode on VM?
Details. Promiscuous mode is a security policy which can be defined at the virtual switch or portgroup level in vSphere ESX/ESXi. A virtual machine, Service Console or VMkernel network interface in a portgroup which allows use of promiscuous mode can see all network traffic traversing the virtual switch.
Should I enable promiscuous mode?
If the Ethernet address display is not turned on and the NIC is in promiscuous mode, it will – incorrectly — show that there are no problems on the network. This may lead to network outages. To prevent such issues, it’s important to use non-promiscuous mode or turn on the Ethernet address display in tcpdump.

Monitor mode only applies to wireless networks, while promiscuous mode can be used on both wired and wireless networks.
How do I know if my interface is in promiscuous mode?
