Cisco Systems IE 3010 Manual De Usuario

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 
Category 5, Category 5e, or Category 6 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.

If auto-MDIX is disabled, use the guidelines in 

 to select the cable for connecting the 

10/100/1000 Ethernet ports to other devices. See the 

 for cable-pinout descriptions. See
