LACP Setup to Cisco 3750G Trunk

[Rickinfl]

Hi,

I setup my Cisco 3750G with a 4 port Port-Channel. I have a Intel 4 Port Nic in my Freenas. I setup the LAGG in Freenas and added the VLAN's. It doesn't seem to work. I'm thinking it's on the Cisco side as the Freenas is pretty simple to create a Lagg. Only thing is I'm running in Truck Mode with multiple Vlan's and I think that's the issue. Here is what I have setup in my Cisco.

Not sure what I've done wrong but if someone could point me in the right direction it would be great.

Thanks!

Dont do it.

Seriously, save the LACP/LAGG/Port Channels for switches of matching models (and firmware). What *exactly* are you looking to accomplish and what does your whole environment look like?

I really need help with this. Let me know if I'm in the wrong place and this is an Cisco Issue.

I'm running a Freenas with a Intel 4 port nic and a Cisco 3750G switch.

Here is the error I'm getting in freenas:

These ports are not ACTIVE on LAGG interface lagg0: em4, em5. Please check cabling and switch.

From freenas console:

I figured this out. Thought I'd post what was the issue in case anyone else had the same issue. I think the problem is my unique combination of hardware with trunking. The 4 port card works fine as just a 4 port nic in Freenas just when you try and trunk the 4 port nic everything goes haywire.

I'm running a Tyan s7012 motherboard it has 4 onboard nics. 2 are igb0, igb1 and the other 2 nics are em0, em1. I installed a
NC364T 4 port nic. Which Freenas seen as em2, em3, em4, em5. For some reason em4 and em5 would not work when trying to create a LACP lagg and my Cisco in LACP and Trunk mode. When I disable the 2 onboard em0 and em1. The em4 and em5 start working on the 4 port card and the LACP connects and works fine. Now I'm running a LACP trunk mode with multiple Vlans.

I've had someone say that the "em" stands for Intel chipsets and the 2 onboard em ports might be somehow conflicting with the 4 port nic card. I might later on try and research this more, but right now this has put me behind weeks so moving forward for now.
