By default, the switch detects whether an RJ-45 connector or SFP module is connected to a dual-purpose port and
configures the port accordingly. You can change this setting and configure the port to recognize only an RJ-45
connector or only an SFP module by using the media type interface configuration command. For more information,
see the Cisco IE 3010 Switch Command Reference.

Connecting to the 10/100 and 10/100/1000 Ports
The 10/100 and 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable
length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires CAT5, CAT5e, or CAT6 UTP cable.
The 10BASE-T traffic uses Category 3 or Category 4 cable.
The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports configure themselves to
operate at the speed of the attached device. If the device does not support autonegotiation, you can set the switch port
speed and duplex parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or
set the port speed and duplex parameters on both ends of the connection.
For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default.
With auto-MDIX enabled, the switch detects the required cable type for copper Ethernet connections and configures the
interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a
10/100/1000 Ethernet port, regardless of the type of connected device.
See the switch software configuration guide or the switch command reference on Cisco.com for more information about
autonegotiation and auto-MDIX.
