The 10/100/1000 switch ports on the Catalyst 3550 can be explicitly set to operate
in any combination of half duplex, full duplex, 10 Mbps, 100 Mbps, or
1000 Mbps. These ports also can be set for speed and duplex autonegotiation,
compliant with IEEE 802.3ab. (The default setting is autonegotiate.) 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 (that is, 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 100 meters.
