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. </div>

You should configure your LAG with this options (custom mode on oVirt):<br />
<br />
mode=4 miimon=100 xmit_hash_policy=2 lacp_rate=1<br />
<br />
An tell to your network admin configure switch:<br />
"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)".<br />
<div id="gt-res-content">
<div class="trans-verified-button-small" dir="ltr" id="gt-res-dir-ctr"><span id="result_box" lang="en"><span>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",<br />
and on one phy interface you should see 1Gb RX, and on another phy interface 1Gb TX.</span></span><br />

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</pre>
