Automatic MDI or MDIX detection

All 10/100 and 1000 Mbps Ethernet copper ports on the devices support automatic Media Dependent Interface (auto-MDI) or automatic Media Dependent Interface Crossover (auto-MDIX) detection. Auto-MDI or auto-MDIX is enabled on all 10/100 and 1000 Mbps copper ports by default. For each port, you can disable auto-MDI or auto-MDIX, designate the port as an MDI port, or designate the port as an MDIX port.

For more information about this feature and how to configure it, refer to the FastIron Ethernet Switch Administration Guide.
