Verify network doesn't work with significant amount of vlan and nodes.
For instance it doesn't work with 400 vlans and 6 nodes. It failed because of timeout.
default timeout 120 isn't enough.

If I decrease vlan amount to 3 it didn't failed, but gave me the results which weren't reliable.
It said that all interfaces on all nodes doesn't work, even admin network which is used for mcollective.
When I tried to check connectivity manually it looks OK.
