1. Check your cabling, it should be straight. Check/test the quality.
2. Hardcode both device to 100Mbps/Full-duplex.
3. Monitor both device interface for any errors. If there is an error, either you have a faulty/wrong cable or faulty port.
Some practice is that they connect both device while the interface is in auto/auto mode to determine which mode to hardcode them. However this doesn't work all the time because there is no standard set for auto/auto, some device although from the same vendor the auto/auto settings fails immediately or overtime causing problem to network. Most internet backbone provider hardcode the speed/duplex whenever possible. Though there are devices that cannot be hardcoded (e.g. PacketShaper GE port, HP-Unix Server port, Some Cisco Switch Model Upstream port).
