Final answer:
To enable auto-MDIX on a network device, one would use a specific command within the device's configuration interface, for example, 'mdix auto' on Cisco devices in interface configuration mode.
Step-by-step explanation:
To enable auto-MDIX on a network device, you would typically use a command within the device's configuration interface. Auto-MDIX (automatic medium-dependent interface crossover) is a technology that automatically detects the required cable connection type (straight-through or crossover) and configures the interface accordingly. This makes it possible to use any type of Ethernet cable to connect devices, regardless of whether they are host or hub devices.
For Cisco devices, for example, the command to enable auto-MDIX would be:
switch(config-if)#mdix auto
You would enter this command on the interface configuration mode for the specific interface you want to configure. Note that not all devices support auto-MDIX, and it is often enabled by default on modern equipment. Always ensure your device supports this feature and that it's appropriate for your network setup before enabling it.
