Configuring Interfaces
Configuring Ethernet Interfaces
To disable auto-MDIX, use the no mdix auto interface configuration command.
This example shows how to enable auto-MDIX on a port:
Switch# configure terminal
Switch(config)# interface GigabitEthernet1/17
Switch(config-if)# no shutdown
Switch(config-if)# speed auto
Switch(config-if)# duplex auto
Switch(config-if)# mdix auto
Switch(config-if)# end
Adding a Description for an Interface
You can add a description about an interface to help you remember its function. The description appears in the output
of these privileged EXEC commands: show configuration
, show running-config, and show interfaces.
Beginning in privileged EXEC mode, follow these steps to add a description for an interface:
Use the no description interface configuration command to delete the description.
This example shows how to add a description on a port and how to verify the description:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface GigabitEthernet1/18
Switch(config-if)# description Connects to Marketing
Switch(config-if)# end
Switch# show interfaces GigabitEthernet1/18 description
Interface Status Protocol Description
Gi 0/2 admin down down Connects to Marketing
