Issue

  • QoS policy with duplicate PGIDs and some policies with unique PGIDs also will not be effective 
  • In mgwd.log a error as below is seen when the policies are being broadcasted to all the nodes in the cluster after a reboot or restart of mgwd service. Below logs show only 117 policy groups were sent to kernel out of 893 because of error detected for pgid 2323 being a duplicate.
