Odd networking issue

[MachineShedFred]

Hello.

I've been trying to pump up the throughput from FreeNAS Corral and I'm seeing some quite odd behavior.

First, a bit about the environment:

Server - 4 x 1000GbE NICs, 2 intel, 2 broadcom
Switch - Cisco 3560G 48-port running C3560 Software (C3560-IPSERVICESK9-M), Version 15.0(2)SE10, RELEASE SOFTWARE (fc2)

Currently, I have one NIC (igb0) configured on a static IP - this is what I've been running on since installing Corral six weeks ago. I added lagg0 which uses igb1, em0, and em1. It shows as up and active in both the switch and the FreeNAS GUI. It has an IP, which responds to pings and I can browse the GUI from it.

However, if I unplug igb0, I still see link on the lagg0 group in both the switch and the CLI, but I can no longer ping the LAGG IP or load the GUI on that IP. All traffic goes dead. Only upon plugging that single connection back in does anything actually talk.

What am I missing? Is there something else I need to adjust, or am I just running into yet another 'Corral-ism' ?

Hello, and welcome to the forums!

You may have missed this: "Important announcement regarding FreeNAS Corral". Sadly, Corral has no future and you'll be best served to either revert to the current stable FreeNAS release (version 9.10) or wait for version 11, due later this month.
