You can argue about semantics all day long but what matters is the actual
performance difference when running full-duplex. I was troubleshooting why
my LTO tape drive wasn't performing as promised. While investigation I
noticed a large number of collisions on a port on a 3524 ( a port connecting
another switch, backup traffic was going from one switch to the other). I
manually set the duplex to full - all collisions stopped and my backups
improved tremendously! Cisco recommends running ports in a full-duplex mode
especially in server farms.
