Moving an Unmanaged Device Into Farm VLAN Fails (4856867)

Typically, after bench configuration, the ports on the shelf are in trunk mode. This configuration prevents you from moving an unmanaged device into a farm VLAN.

Workaround: Change the unmanaged device port from trunk mode to hybrid mode. Then, add the unmanaged device to the VLAN.
