Appendix C Configuring the Switch with the CLI-Based Setup Program

Accessing the CLI Through the Console Port


If the switch modules are ordered with the server chassis, the switch modules are already installed, and
no unpacking is required. The unpacking procedure applies only if a switch module is ordered separately.


You need to provide the Category 5 straight-through cables to connect the switch ports to other Ethernet


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 10/100/1000 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, refer to the switch software
configuration guide or the switch command reference.
