Is there a command line way to tell me whether a ethernet
connection is
100 BaseT or Gigabit Ethernet?
mii-tool
My experience with mii-tool on CentOS4 and 5 is that it won't show link speed above 100 even if it is. If the OP is trying to differentiate 100 vs. 1000, then I would suggest using ethtool instead.
