Symptoms

After applying the changes, you get presented with both the slaves, and the bond itself is down.

Solution

Upgrade to firmware 1.6.1 or above.

If you need a workaround right now, you can follow these steps:

  1. Log into the appliance as root.

  2. Restart the networking service:

    root@linux~# systemctl restart networking.service

    .

  3. This will lead to a working configuration.
