What is a promiscuous mode in Vmware?

• Promiscuous mode is a security policy which can be defined at the virtual switch or portgroup level
• 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.
• If this mode is set to reject, the packets are sent to intended port so that the intended virtual machine will only be able to see the communication.
• Example: In case you are using a virtual xp inside any Windows VM. If promiscuous mode is set to reject then the virtual xp won’t be able to connect the network unless promiscuous mode is enabled for the Windows VM.
