Hi Scott,
When I execute below statements in linux to change the mac address I get the=
error Host name look up error.
Below are the commands I execute to change the mac address and the console o=
utput.
1. ifconfig eth0.246 down
2. ifconfig eth0.246 hw ether 00:11:22:33:44:55
ifconfig: hw: Host name lookup failure

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
