I have a problem on a 3560 with regards to packet throughput between an incoming 1Gb port and outgoing 100Mb port.
No matter what configuration I put on the 3560, QoS and otherwise, a burst of traffic coming from a device on the 1Gb port destined for a device on the 100Mb port always suffers from packet drops.
If I replace the 3560 with a 2950 with incoming 1Gb and outgoing 100Mb no such packet drops occur.
Can anyone tell me why the 3560 cannot perform as the 2950 does.
The burst of traffic is 30Mb of udp traffic, each packet being 1494 bytes, and lasts for 3.5 seconds. When analysed this is transmitting at about 70Mb per second.
The 3560 always drops packets no matter what I configure but the 2950 doesn't.
Any answers would be greatfully received.
