 Subject:  Re: [m0n0wall] Frame Errors WRAP - BayStack Switch when forcing Ports to 100/full-duplex

The NIC manifacturer are mostly not "so correct" in regards of timing and 
usually also a 20cm cable will work but if you want to stay within the standard, 
keep at least 2.5m between two nodes.
Anything else may work but does not have to.
