Ubuntu 14.04 bond (balance-rr) down but slaves are up

0

I am trying to setup balance-rr on my Ubuntu 14.04 server. I have a USB 3.0 dual NIC adapter (eth1 and eth2). It is direct connected to my NAS. It was working and then I rebooted and now it isn't working. I can't seem to get it to work now and I don't see anything wrong. Here are all of the files I can think that are relevant. Both of the slave interfaces appear to be working correctly but the bond is down. Is there something I am missing? Thanks!

Replace the line bond-slaves none to bond-slaves eth1 eth2 in configuration file /etc/network/interfaces.

The issue was hardware/driver related. I purchased a different USB 3.0 to dual gigabit adapter and installed the supplied drivers. Using the config above it works perfectly.

StarTech USB 3.0 to Dual Gigabit Ethernet Adapter (USB32000SPT) - does not work

Vantec USB 3.0 to Dual Gigabit Ethernet Network Adapter (CB-U320GNA) - works
