I am currently experiencing the same issue. 2x nic lacp config at switch, mode 4 bond at server with no connectivity. Interestingly I am able to ping the switch itself.<br>
<br>
I haven't had time to investigate thoroughly but my first thought is an update somewhere.<br>
<br>
Did you ever resolve and get back to mode=4?<br>

But the machine is UP,<br /> only the network stop to work for some minutes.<br /> I activate global maintenace mode to prevent engine reboot. If I ssh <br /> to the hosted engine sometimes<br /> the connection work and sometimes no. Using VNC connection to engine <br /> I see that sometime VM reach external network<br /> and sometimes no.<br /> If I do a tcpdump on phisical ethernet interface I don't see any <br /> packet when network on vm don't work.<br /><br /> Same thing happens fo others two VM.<br /><br /> Before the upgrade I never had network problems.<br
