Thanks Pietro!
Somehow the man-page for ifconfig is confusing....
In the examples:
<quote>
Add the IPv6 address 2001:DB8:DBDB::123/48 to the interface em0:
# ifconfig em0 inet6 2001:db8:bdbd::123 prefixlen 48 alias
Note that lower case hexadecimal IPv6 addresses are acceptable.
Remove the IPv6 address added in the above example, using the / character
as shorthand for the network prefix, and using delete as a synonym for
the canonical form of the option -alias:
# ifconfig em0 inet6 2001:db8:bdbd::123/48 delete
</quote>
Lesson for me is that you should have only one 'command' per
invocation where I had 2. alias is not an atribute/option of the
setting I was trying to do....
Kind regards,
Spil.
