As described in DE588,
"With neutron multiworkers configured, there is a potential race condition
issue where some of the VLANs will not be configured on one or more N9k
switches.
Fix is to allow the vlan create command to be sent down to a switch
under most event conditions. Long term fix will be to introduce a new
column in the port binding DB table that indicates the true state of the
entry/row.
