Error when creating network [closed]

Hi there! I have a fresh install of Mitaka on Ubuntu 14.04 using mirantis fuel 9.2, in my setup I have the following topology:

3 controller nodes

1 cinder node

1 compute node

all of them installed over IBM x240 server nodes

For networking I deployed Neutron with tunneling segmentation, and my issue is that I need to add some external networks to my environment (with VLAN as provider network type), and when I create it in horizon I get the message "Error: Failed to create network test"

I turned debug on for neutron in one controller node but I cannot find any message at fuel logs, any ideas what could be wrong? I know that it is possible to create it by command line, but it would be great to find the reason of horizon failure and be able to create external networks with it

thanks in adv!

If I submit: neutron --debug net-create --provider:physical_network=physnet1 --provider:network_type=vlan --provider:segmentation_id=1956 --shared --router:external testVLAN

Output: BadRequest: Invalid input for operation: physical_network 'physnet1' unknown for VLAN provider network.

Solved! Issue was that VLANs were not defined in /etc/neutron/plugins/ml2/ml2_conf.ini in line "network_vlan_ranges" after setting that and restarting neutron/openvirtualswitch services it worked great!
