Link aggregation not working

Post by jmix951 »

Hi Guys,

I am very new to Nas4Free and have no BSD knowledge; I was trying to aggregate 4 NIC (2 onboards (MOB GA EP45 UD 3P) and 2 Realtek (tP-Link)).

I run through this procedure viewtopic.php?t=357 :

In the WebGUI, goto Network --> Interface Management and click the "+" button to add the new interface. This should leave you with two entries in the Management tab (LAN & OPT1). When done click the Save button but DO NOT REBOOT.
In Network --> Interface Management click the LAGG tab. Click the "+" button to add an interface. Interface should already be called "lagg0". In Aggregation Protocol select LACP Link Aggregation Control Protocol. In Ports select both interfaces. In Description just enter any name to identify the new aggregated adapter. Then click the ADD button.
Go back to the Management tab and the "+" button should now be visible because there is now a new adapter ready to be added. Click the "+" button to add the LAGG interface. This should add an interface to the list labelled OPT2 with the network port column as lagg0 followed by the name you gave it in brackets.
Now, still in the Management tab, using the drop downs rearrange the interface order so that the LAN interface is now the lagg0 and the two original interfaces are OPT1 and OPT2. Now click SAVE.
Double check that the interfaces are listed as LAN = lagg0, OPT1 = (first physical adapter) and OPT2 = (second physical adapter).
Click Network --> LAN and check that the IP address etc is correct for your network.
Reboot FreeNAS. Once rebooted check connection with the WebGUI.


I reboot before adding the cables; I'm never able to reconnect via GUI and the NAS does not appear on my Router's connected devices.

I am using a NETGEAR GS724T V4 switch and I LACP'd the 4 ports for the connection.

Please help; this is driving me crazy; even had a look at going OMV :shock:

Thanks a lot for your assistance.

Your router support LACP as it is working very nice for me though i use 10Gbps cards for transfer.
But the 8 1Gbps is set in LACP with switches i have, so streaming and transfer of files in that subnet has good speed.

Waist of cards for sure as my network is not that big.

Your NETGEAR GS724T switch needs to support LAGP. I just did this last night on a powerconnect 6248 switch. I just lag the 4 ports and it didn't work. Took a look an /conf/config.xml and noticed the protocol was LACP, went back and set the 4 ports to LACP as well and it worked.
