I have been using this in production since April or early May, but 3.1-RELEASE will panic your system if you try this! ( it is possible to use a more recent if_vlan.c and eliminate the panic.) I have a 3.2 BETA from 24 May that is routing between 10 networks. How to implement. 1) edit your kernel configuration file, adding the following line, pseudo-device vlan n where n is the number of vlan devices you want. 2) build and install kernel as usual. 3) get, build and install a version if ifconfig that supports configuring vlan devices. A copy can be obtained from ftp://196.31.225.208/pub/FreeBSD/misc/ifconfig-vlan.tgz ( I have lost the email address of the person that sent this to me, he may now have an improved version. make install does not work, I have not looked at it.) The man page included expains the new vlan options. 4) add the apropriate entries to your rc.conf eg. ifconfig_xl0="inet 192.168.225.199 netmask 255.255.255.0" fconfig_vlan0="inet 192.168.25.199 netmask 255.255.255.0 vlan 2 vlandev xl0" network_interfaces="xl0 vlan0 lo0" important it is possible to have one untagged vlan on the interface, as above. If you do not have an untagged vlan on the interface, then you must enable the interface. ie ifconfig xl0 up. 5) reboot your syestem to start your new kernel and interfaces. dont forget to configure your switch. Good luck, Tim.
