Mime-Version: 1.0 Content-type: text/plain; charset=us-ascii Content-Disposition: inline Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org For me this looks like Solaris.. I dont know if this is some System V related feature. In BSD you cant create this sub-interfaces you want. It is always the same hardware beneath. Ifconfig offers aliasing, if you want the adapter to listen on another Ip-adress in addition to the adress you gave it initially. "Alias" is some sort of misnomer, I think. You can put a lot of IP definitons on a Interface, but they are completely equal, there is no preference between them. You can give a interface a first adress, then a "alias", remove the first adress treating it as an alias and then you will have the same interface as if it would have been configured with this "alias" adress right at the beginning. --Orm > On Mon, 24 Jul 2000, f.johan.beisser wrote: > > > fxp0 flags=8843 mtu=1500 > > inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255 > > fxp0.1 flags=8843 mtu=1500 > > inet 192.168.0.2 netmask 0xffffffff broadcast 192.168.0.255 > > etc... > > Hmm... like cisco subifs.
