Hi Smitha,
first of: please try changing the MAC of the adapter, not of the virtual
interface (btw: are you sure, that you really intend to have a physical
and a virtual interface that have the same configurations and the same
metric?).
second: guess your copy+pasted log shows: that you concatenated
"ifconfig eth0.246 up" to the actual MAC address change command by
accident. Please try again, without these additional (surely non
working) parameters.
Regards,
lorenz
