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
