Duplex mis-match. (This should also produce CRC and framing errors). Auto-negotiation of duplex often fails. We always lock our ports down if they are permanently connected to a device. Speed detection is quite reliable. 2. 802.1q VLAN trunking. The VLAN header expands the packet by 2 octets which exceeds the old 802.3 limit on frame size for full 1500 byte packets. Lowering the MTU by 2 on the sending systems might fix this, but the header is normally removed by the last switch to process the frame. This might indicate a mis-configured switch. R.
