our customer told me about his poor tranfer rate if he connect his Intel Pro 1000 MT NIC with latest driver software to a WS-C3560G-48TS (12.2(44)SE) at 1Gbps. The connection endpoints were set to auto. Allegedly the Intel Pro does not allow to hardcoded the speed/duplex to 1000 Full. If the speed was hardcoded to 100 Mbps at swtich side, than the transfer rate is OK. Does anyone notice this behaviour?
