+The vlan, vlandev, and -vlandev options +are now deprecated in favour of vnetid, -vnetid, +parent, and -parent when using ifconfig(8) or +in hostname.if(8) configuration files. +Use of the vlan option must be replaced with vnetid. +Because VLAN tag 0 is invalid according to the relevant VLAN +specifications, the vnetid option does not accept 0 as a +valid network identifier. +To use VLAN tag 0 on the wire the vnetid can be unconfigured with +-vnetid. +Use of vlandev and -vlandev must be replaced with +parent and -parent respectively. + +
+Unlike vlan and vlandev, vnetid and +parent do not implicitely bring the vlan interface up. +Similarly, the vlan option is no longer implied by the +interfaces minor when it is not explicitely set. + +
+ifconfig(8) +no longer outputs a vlan specific status line, or separate vnetid +and parent lines. +The vnetid and parent lines have been merged into a single encap +line containing the VLAN tag and parent information. + +
An example of the changes to a vlan(4) configuration file and +the ifconfig(8) output is below. Before the changes: + +
+ ++# cat /etc/hostname.vlan7 +vlandev em0 # vlan 7 and up are implied +lladdr random +# ifconfig vlan7 +vlan7: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 + lladdr 70:a7:3a:75:da:2d + index 7 priority 0 llprio 3 + vlan: 7 parent interface: em0 + vnetid: 7 + parent: em0 + status: active +
+After the changes: + +
++# cat /etc/hostname.vlan7 +vnetid 7 parent em0 +up +lladdr random +# ifconfig vlan7 +vlan7: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 + lladdr 60:e8:d7:0d:10:6d + index 7 priority 0 llprio 3 + encap: vnetid 7 parent: em0 + groups: vlan + status: active +
