7 Expand Security and accept or reject promiscuous mode, MAC address changes, and forged transmits
of the virtual machines aached to the standard switch.
Option Description
Promiscuous mode
n
Reject. The VM network adapter receives only frames that are
addressed to the virtual machine.
n
Accept.The virtual switch forwards all frames to the virtual machine in
compliance with the active VLAN policy for the port to which the VM
network adapter is connected.
N Promiscuous mode is insecure mode of operation. Firewalls, port
scanners, intrusion detection systems, must run in promiscuous mode.
MAC address changes
n
Reject. If the guest OS changes the eective MAC address of the
virtual machine to a value that is dierent from the MAC address of
the VM network adapter (set in the .vmx conguration le), the switch
drops all inbound frames to the adapter.
If the guest OS changes the eective MAC address of the virtual
machine back to the MAC address of the VM network adapter, the
virtual machine receives frames again.
n
Accept. If the guest OS changes the eective MAC address of the
virtual machine to a value that is dierent from the MAC address of
the VM network adapter, the switch allows frames to the new address
to pass.
Forged transmits
n
Reject. The switch drops any outbound frame from a virtual machine
adapter with a source MAC address that is dierent from the one in
the .vmx conguration le.
n
Accept. The switch does not perform ltering, and permits all
outbound frames.
