After further testing we can either get EM1 running on the bond or EM2 - EM4 running in the bond, but not EM1-EM4. We are running the Hosted Engine Appliance in our setup. In order to install the appliance, i have to point it to a physical nic during the install process. The install process creates the network bridge ovirtmgmt which is tied to interface EM1 on both servers. After i finished setting up the appliance, and both of my hosts, i went in and created my bond so i could configure LACP. It seems that is some disconnect between my network bridge, the bond and my interfaces. I would like to some how get my bond to use all 4 interfaces. On reboot, it always seems to reset consistently to EM1. -----Original Message----- From: Konstantin Shalygin <k0ste@k0ste.ru> To: users@ovirt.org, Bryan Sockel <Bryan.Sockel@altn.com> Date: Thu, 20 Apr 2017 23:43:15 +0700 Subject: Re: Re: [ovirt-users] LACP Bonding issue You should configure your LAG with this options (custom mode on oVirt): mode=4 miimon=100 xmit_hash_policy=2 lacp_rate=1 An tell to your network admin configure switch: "Give me lacp timeout short with channel-group mode active. Also set port-channel load-balance src-dst-mac-ip (or src-dst-ip\src-dst-mac)". You also need to understand that LACP balancing works 'per flow'. You can take 2 hosts and run "iperf -c xxx.xxx.xxx.xxx -i 0.1 -d", and on one phy interface you should see 1Gb RX, and on another phy interface 1Gb TX. Hi, I discovered an issue with my LACP configuration and i am having trouble figuring it out. I am running 2 Dell Powered 610's with 4 broadcomm nics. I am trying to bond them together, however only one of the nics goes active no mater how much traffic i push across the links. I have spoken to my network admin, and says that the switch ports are configured and can only see one active link on the switch. Thanks Bryan
