Link Aggregation on i210 working but need to edit rc.conf

I finally got link aggregation working on 9.2.0.1.943. I am running a Asrock E3C226D2I board with dual Intel i210 nics onboard.
It seems the webgui doesn't modify /etc/rc.conf properly when the LAGG interface is created.

Although setting up lag in the gui puts the correct lines in /etc/rc.conf:

Code: Select all

ifconfig_igb0="up"
ifconfig_igb1="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto lacp laggport igb0 laggport igb1"
ipv4_addrs_lagg0="192.168.1.100/24"

but the gui didn't remove the reference to the previous interface:

Code: Select all

ipv4_addrs_igb0="192.168.1.100/24"
At this state, my traffic was not passed properly, unable to reach the nas. removing the ipv4_addrs_igb0="192.168.1.100/24" line in /etc/rc.conf fixes this and link aggregation works as it should. This also fixes the "dhcp: bad value" error I was getting during boot up.

Right now i'm pushing 190mb/s into the my server :)
