Appendix C Configuring the Switch with the CLI-Based Setup Program
Connecting to the Console Port
Note You need to provide the Category 5 straight-through cables to connect the switch ports to other Ethernet
devices.
Note 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.
Connecting to the Console Port
You can use the console port to perform the initial configuration as an alternative to using Express Setup.
To connect the switch console port to a PC, use the supplied RJ-45-to-DB-9 adapter cable.
Follow these steps to connect the PC or terminal to the switch:
Step 1 Using the supplied RJ-45-to-DB-9 adapter cable, insert the RJ-45 connector into the console port on the
rear of a switch, as shown in Figure C-2.
Step 2 Attach the DB-9 female DTE of the adapter cable to a PC serial port, or attach an appropriate adapter to
the terminal.
