Title:
  Hyper-V agent does not add new VLAN ids to the external port's trunked
  list on Hyper-V 2008 R2

Status in networking-hyperv:
  Fix Released
Status in neutron:

Status in neutron juno series:
  Fix Committed

Bug description:
  This issue affects Hyper-V 2008 R2 and does not affect Hyper-V 2012
  and above.

  The Hyper-V agent is correctly setting the VLAN ID and access mode
  settings on the vmswitch ports associated with a VM, but not on the
  trunked list associated with an external port. This is a required
  configuration.

  A workaround consists in setting the external port trunked list to
  contain all possible VLAN ids expected to be used in neutron's network
  configuration as provided by the following script:
