I'm see the exact same symptoms on our ASR1002's. we effectively have heirarchical QoS configured, or CB shaping. I don't see any of the shape rate CIR's being exceeded, yet I see extensive random/tail drops occuring when the physical interface tra...

That's the same result I got. You have to combine the tweaks. If you put the shaping back to 4ms you'll see your drops increase even with increased queue depths. I do highly recommend making the excess bust bucket on shaping proportionately larger th...

Let me know how it works out. I can't gaurantee it will completely stop packet loss altogether but it will cut down on it immensely. When you begin to sustain the cir continuously your queue will always have a high fill level and more drops will occu...

I forgot to mention...if you want to use the policer to meter the packet flow make sure your actions are "transmit" for everything. The goal is to simply compare the exceed/violate packet count to the number of drops on the shaping policy. I also wan...

Tac case is closed. The problem centers around a few things. The shape cir, the queue depth, and the actual rate of packet flow. Low shape rates with flows serialized from high speed sources (100Mbps and higher) represent problems for traffic shaping...

The default burst in the llq defaults to 20% of the configured priority. When you consider the single rate, two color policer operation and how traffic is metered it becomes clear that the llq will police traffic at 20% of the configured priority unl...
