If you are using VRRP, you need to define a VRRP sync-group, and use ``vrrp sync-group`` instead of ``cluster group``.
.. code-block:: sh
set high-availablilty vrrp group internal virtual-address ... etc ...
set high-availability vrrp sync-group syncgrp member 'internal'
set service conntrack-sync failover-mechanism vrrp sync-group 'syncgrp'

.. code-block:: sh
$ show conntrack-sync statistics
