Appendix C Configuring the Switch with the CLI-Based Setup Program
Stacking the Switches (Optional)
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, refer to the switch software
configuration guide or the switch command reference.
Stacking the Switches (Optional)
You can stack up to nine switches by using the StackWise cables and ports to
connect the switches.
Read the “Planning the Stack” section on page 3-14 before you stack your
switches.
