As soon as I change the HTTP queue to be allowed only 5 percent instead of 40 percent, the router almost completely stops dropping packets in the class-default queue: Class-map: HTTP (match-any) 86935 packets, 5150618 bytes 5 minute offered rate 1000 bps, drop rate 0 bps Match: access-group 101 86935 packets, 5150618 bytes 5 minute rate 1000 bps Queueing Output Queue: Conversation 266 Bandwidth 5 (%) Max Threshold 64 (packets) (pkts matched/bytes matched) 86204/5106232 (depth/total drops/no-buffer drops) 0/0/0 Troubleshooting a Converged Network Class-map: class-default (match-any) 26519010 packets, 2404610690 bytes 5 minute offered rate 849000 bps, drop rate 0 bps Match: any Queueing Flow Based Fair Queueing Maximum Number of Hashed Queues 256 (total queued/total drops/no-buffer drops) 0/32252/0 The trick here is that the configuration of one queue directly affected the behavior of another queue-specifically, the one beneath it. In this case, there was nothing I could have done to the class-default queue to increase its performance; the changes had to be made to the queue above it. Default Queue Too Small The size of the class-default queue is not directly configurable. If the queue is too small, either the link is too small, or the other queues are too large. In either case, you'll end up dropping packets in the class-default queue. Default Queue Too Large I would argue that the default queue cannot be too large. If you have a large class- default queue, you have ample bandwidth and life should be good-for now, anyway! Chapter 32: The Converged Network PART VIII Designing Networks This section covers network design in a way that you won't see on certification exams. Instead of focusing on the technical details, I'll begin by walking you through the complete pr
