10/100 and 10/100/1000 Ports
You can set the 10/100 ports on the Catalyst 3750 switches to operate in any
combination of half duplex, full duplex, 10 Mbps, or 100 Mbps. You can set the
10/100/1000 ports to operate in 10 or 100 Mbps in half or full duplex, or in
1000 Mbps in full duplex.
You can set both the 10/100 and the 10/100/1000 ports for speed and duplex
autonegotiation, in compliance with IEEE 802.3AB. (The default setting is
autonegotiate.)
Note You can configure duplex mode to half, full, or autonegotiate on Gigabit Ethernet
interfaces if the speed is set to 10 or 100 Mbps. You cannot configure half-duplex
mode on Gigabit Ethernet interfaces if the interface speed is 1000 Mbps.
When set for autonegotiation, the port senses the speed and duplex settings of the
attached device and advertises its own capabilities. If the connected device also
supports autonegotiation, the switch port negotiates the best connection (the
fastest line speed that both devices support and full-duplex transmission if the
attached device supports it) and configures itself accordingly. In all cases, the
attached device must be within 328 feet (100 meters).
