Problem

When creating a bond in Advanced mode of the Network Settings and assigning a VLAN configuration, the bond will not come up after saving.

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.
