I have seen this too, and like Ian I would normally go with 100/Full manually configured on botht he Cat and the end device (obviously assuming both devices support this settings). In real life, I have often found that setting the cat to Auto will often lead to duplex / speed mismatches (especially with Sun kit) The only time I have made use of Auto is when I am not 100% sure if the end device support 100MB, some of our legacy printers are 10MB half duplex, and indeed a number of the 2511's are only 10MB too.]
