Interfaces are created based on what is present in the kernel and what hardware is present on your system. The configuration of those interfaces (e.g. associated IP addresses, media options, etc.) is done at runtime by scripts in /etc. Those scripts use rc.conf to determine how to configure the interfaces. So if you do: ifconfig_bge0="inet 192.168.0.1/24" Then your bge0 interface will be configured with those settings on boot (or when you do /etc/rc.d/netif restart). If there is no bge0 interface on your system, however, because the hardware is not present or the driver is not in your kernel (or loaded as a module), then nothing will happen. That interface will not be created. You can create some kinds of interfaces dynamically, and you can rename interfaces, but those things are probably a distraction from what you want and excessively confusing. In general, interfaces do not come from the configuration files like rc.conf, however the way that those interfaces are set up on boot is configured by files like rc.conf. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
