you need to provide the category 5 straight-through cables to connect the switch ports to other ethernet devices.
you can use the mdix auto interface configuration command in the cli to enable the automatic medium-dependent interface crossover (auto-mdix) feature. when the auto-mdix feature is enabled, the switch detects the required cable type for copper ethernet connections and configures the interfaces accordingly. therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100, 10/100/1000, or 1000base-t sfp module port on the switch, regardless of the type of device on the other end of the connection.
the auto-mdix feature is enabled by default on switches running cisco ios release 12.2(18)se or later. for releases between cisco ios release 12.1(14)ea1 and 12.2(18)se, the auto-mdix feature is disabled by default. for configuration information for this feature, see the switch software configuration guide or the switch command reference.
