Syntax:

                          #ifconfig qe0:1 plumb

                          # ifconfig qe0:1 10.10.1.150 up

    where "qe0" is an interface (e.g., le0) and N is a number between 1 and
    <MAX>.  Removing the pseudo interface and associated address is done
    with "ifconfig qe0:1  10.10.1.150 down".

    As with physical interfaces, all you need to do is make the
    appropriate /etc/hostname.qe0:X file.

ifconfig qe0:1 plumb 10.10.1.150 netmask <netmask> up

For making it persistant after reboot, we can add /etc/hostname.qe0:1 file with hostname inside it. Also we can map the ip address to hostname in the /etc/hosts.
