Dear all,
I found that when I enabled layer 2 auto QoS in 3560 switch, I need to wait so much time to open a file in network drive. Howerver, when I disable the Qos. It can improve a lot. I have used a sniffer to capture the packet to see. Those default packet is in DSCP 0. Therefore, I think majority packet will drop to queue 4. How can I increase the buffer and threshold in order to improve queue 4 performance.
