Hi Everyone,
We've run into a problem with tail drops on a couple of service on ME3600's....our "usual" shaping policy (For example 10Mb) would be: policy-map CUSTA_10M class class-default shape average 9800000 int foo service instance 1065 ethernet description CUST_A encapsulation dot1q 1065 rewrite ingress tag pop 1 symmetric service-policy output CUSTA_10M bridge-domain 1065 Which has worked historically without problem....but now we are seeing tail drop/poor performance on "some" of these services with shaping....Ive been doing some reading, and adjusting queue limit alleviates the issue? Ive tried adding "queue-limit percent 100" to the shaping policy, but it gets rejected: QOS: queue-limit command not supported in non-leaf classes QoS: Policy attachment failed for policymap CUSTA_10M Ive had a bit of a google, and have seen examples where people have used a "dummy class" class-map match-all CM-DUMMY <-- Had to create this or policy map complained and would not apply it policy-map MB_TEST_10Mb class CM-DUMMY class class-default shape average 9800000 queue-limit percent 100 but attempting to apply to a service instance I am still getting the "QOS: queue-limit command not supported in non-leaf classes" Any help is greatly appreciated.
