For the QoS on the 3750 switch would the following meet the requirements 1. Switchport egree priority queue - 2. Ensure input queue #1 is configured as priority input queue with 20% of the bandwidth 3. Remaining bandwidth should be serviced by SRR equally

DPS There are no secrets to success. It is the result of preparation, hard work, and learning from failure
