Bug ID: 211436
Summary: Link aggregation setting wlan mac changed in 11
Product: Documentation
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Documentation
Assignee: freeb...@FreeBSD.org
Reporter: rwes...@gmail.com

The handbook shows setting up wifi/ethernet failover like this:

> ifconfig_bge0="up"
> ifconfig_iwn0="ether 00:21:70:da:ae:37"
> wlans_iwn0="wlan0"
> ifconfig_wlan0="WPA"
> cloned_interfaces="lagg0"
> ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"

As of FreeBSD 11, this no longer works. The correct way is like this:

> ifconfig_bge0="up"
> create_args_wlan0="wlanaddr 00:21:70:da:ae:37"
> wlans_iwn0="wlan0"
> ifconfig_wlan0="WPA"
> cloned_interfaces="lagg0"
> ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"


The relevant section is 30.7, example 30.3.

According to this discussion/patch
(https://lists.freebsd.org/pipermail/freebsd-current/2015-September/057403.html)
it is better to change the MAC address of the Ethernet card instead of the
wireless device. As an added bonus this should work for FreeBSD 9 and 10, too.

Ah, thanks for the link. In that case, I think the correct example should be
this:

> ifconfig_bge0="ether 00:21:70:da:ae:37 up"
> wlans_iwn0="wlan0"
> ifconfig_wlan0="WPA"
> cloned_interfaces="lagg0"
> ifconfig_lagg0="laggproto failover laggport bge0 laggport wlan0 DHCP"
