SOLVED LACP and IPMI

[eroji]

I am running on a ASRock EP2C602-4L/D16 board and there is a dedicated BMC/IPMI port and 4 Intel LAN ports. However, I noticed that IPMI always seems to grab 2 IPs and showing there are 2 NICs associated. When I tried to configure LACP in FreeNAS, after adding all 4 Intel LAN NICs, it would kill my IPMI connection. I ended up having to reboot the server just to access the IPMI again, and what I saw was both NICs in IPMI also became bonded. Not quite sure why this is, but I did read somewhere that often LAN1 also has a channel that is allocated for IPMI. Can anyone advise on what is the best series of steps to get LACP working on all 4 LAN ports?

There should be an option in IPMI settings to not share the LAN ports with IPMI. It appears there is a dedicated IPMI port

I did not see that option. Only the 2 NICs in BIOS. I'll take a screenshot when I get home.

 

[pirateghost]

instead of BIOS, look at the IPMI settings in the IPMI

 

[eroji]

Will try and check. As I recall, it has the option to enable or disable eth0 or eth1 and nothing else. Similar to BIOS settings.

At least on Supermicro X10s, the options are shared or fallback. No true dedicated option.

I think I found the port that it's piggybacking off. I turned off IPMI on it for now. Will try the LACP configuration again later.

 

[pirateghost]

May I ask how many clients you have that you feel LACP would benefit you?

 

[eroji]

It's actually for homelab use. The number of users is under 10 but there will be a good amount of copying stuff back and forth of large files and since the board came with 4 NICs, it shouldn't hurt to turn it on.

Except that's not the way LACP works

;)

 

[eroji]

You are right, I just realized I should be asking about static LAG instead. My bad.

 

[pirateghost]

You should probably read up on LAGG and LACP a bit first.

You aren't going to magically increase your speed. ;)

Yes that I do know. It's purely for concurrent throughput for multiple users/connections.

Yes, but also if your network switch doesn't implement it very well it will create a whole host of new problems. :P

Just a heads up, the dedicated interface is labeled eth1 in Megarac gui. Leave that one alone. Don't ask....

 

[eroji]

Yea I figured that out by pulling the cables one by one. If only the ordering of the ports and names made some sense...
