This attribute specifies the mode of operation of the Vm If. Two
modes are supported: alwaysUpInterface and interVrConnection.
alwaysUpInterface: This mode limits the Vm If to provide the
functionality of an 'always up interface' only. Inter-VR
communcation is not possible when this mode is selected. Memory
consumption by the Vm If is significantly less on FP when this
mode is selected. Hence this mode should be used when the sole
purpose of the Vm If is to provide an always up interface for
application like BGP4.
interVrConnection: This mode provides the full capability of
VirtualMedia, i.e. 'always up interface' and inter-VR
communication.
