The priority defined for queuing is not mandatory and hence become priority entry based on whether defined or not. Similarly for min-rate, max-rate. There is no specific reference to MDRR. The queuing actions are defined as per classifier entry or as separate queuing policy.

If there is no reference to MDRR, I find the following confusing:


     identity mdrr-queuing-policy {
       base compc-qos-policy;
     }

   ...
         must "((../sub-type != 'mdrr-queuing-policy') and " +
              " (../sub-type != 'pwfq-queuing-policy')) or " +
              "(((../sub-type = 'mdrr-queuing-policy') or " +
              "  (../sub-type = 'pwfq-queueing-policy')) and " +
   ...

       container traffic-queue {
         when "(../sub-type = 'mdrr-queuing-policy') or " +
              "(../sub-type = 'pwfq-queuing-policy')" {
           description
             "Queuing policy properties";
         }
(Twice)
   ...
       case mdrr-queuing-policy {
         when "../../../sub-type = 'mdrr-queuing-policy'" {
           description
             "MDRR queue handling properties for the traffic " +
             "classified into current queue";
         }
         leaf mdrr-queue-weight {
           type uint8 {
             range "20..100";
           }
           units percentage;
         }
       }
