Displaying the Interface Auto-MDIX Configuration

To display the interface speed and duplex mode configuration for an interface, perform this task:
Command
Step 1
Switch> enable
Step 2
Switch# show interfaces type slot/interface
Depending on how the speed auto and the mdix auto commands are configured on a supported line card
interface, the show interfaces command displays the following possible auto-MDIX statuses:
Table 8-4

Auto-MDIX Setting and Operational State
on an Interface
Auto-MDIX on (operational: on)
Auto-MDIX on (operational: off)
Auto-MDIX off
This example show s how to display the auto-MDIX configuration setting and its operational state on

Displays the interface auto-MDIX configuration setting and
operational state.
Description
Auto-MDIX is enabled and is fully functioning.
Auto-MDIX is enabled on this interface but it is
not functioning. To allow auto-MDIX feature to
function properly, you must also set the interface
speed to be autonegotiated.
Auto-MDIX has been disabled with the
no mdix auto command.
