The process we used to create our vLAN interfaces: ifconfig bge0 up ifconfig vlan100 create ifconfig vlan100 inet 10.0.0.1/24 vlan 100 vlandev bge0 The first line brings the parent interface up and establishes the connection to the switch. The second line create the vlan100 interface. The number can be anything you want, so long as it is unique for all vlan interfaces. The third line configures the IP on the vlan100 interface, sets the vlan number (to tag the packets with) and associates it with the parent interface. Any packets you route through vlan100 will have the vlan 100 tag added/removed as needed. The lines needed in /etc/rc.conf to automate this are: cloned_interfaces="vlan100" ifconfig_bge0="up" ifconfig_vlan100="inet 10.0.0.1/24 vlan 100 vlandev bge0" See the ifconfig(8) and rc.conf(5) man pages, and the comments in /etc/defaults/rc.conf for more info. -- Freddie Cash fcash@ocis.net
