How to enable WoL on a LAGG?

[Atomic]

Hi Forum,

I am trying to enable WoL on my FreeNAS which is connected to the network by a link aggregation group.

Thanks for any help.

Does it work without lagg? And I don't think lagg should affect anything.

Hi,

it worked once but that's long ago. The problem is, that FreeNAS only supports WoL on interface re0 und I don't have an interface re0, just lagg0.

[root@freenas] ~# ifconfig re0 wol wol_ucast wol_mcast wol_magic
ifconfig: interface re0 does not exist

Weird claim to make, has no basis in reality that I'm aware of.

FreeNAS may allow WoL on any hardware that's capable of supporting it, but WoL is a finicky beast.

For WoL, you need an ethernet device that supports it (your S1200KP appears to have two em interfaces, and the first one at least probably does support it). Try sending the magic packet to the ethernet address on em0. If that doesn't work, look through the BIOS for settings that might be interfering ("Wake on LAN", "Wake on PME", etc) and try again. If that doesn't work, you're probably out of luck. I expect it'll just magically wake up if you hit that em0 address though.

Adding a Realtek ethernet interface won't help; the reason WoL "works" on an "re0" interface is if you've got a Realtek on the motherboard, and the motherboard manufacturer has set up WoL support, then the necessary extras to make this all magically wake up the PC have been handled by the manufacturer. It used to be that WoL with an add-on card was supported via a three pin hardware header, but that became obsolete and then manufacturers used PME for that, and then with the advent of built-on ethernets on motherboards, most consumer boards don't even seem to work with that. I've seen it work on server boards though.

Hi,

the Intel S1200kp board supports WoL and it's enabled in the BIOS (Wake on LAN from S4/S5 -> Power On - Normal Boot). WoL worked until some update in the past, when they had general problems with the WoL function. But I just set my FreeNAS completely new up (version 9.3).

I use the OS X application iNet for the Wake on LAN feature, in the future I want to boot the FreeNAS automatically when I switch on the Mac.

WoL is not an officially supported feature of FreeNAS. If it works, that is just a magical optional extra that may also stop working again at any time. :)

What a shame. :(
