22.4.2 Ethernet Interface Settings
For an Ethernet interface, use the command corresponding to the interface to be connected to switch to the applicable mode, and then set the configuration. The following table describes the port types and the corresponding mode transition commands.

(1) Configuration settings for an interface
- Points to note
-
Configuring an Ethernet interface might require the execution of multiple commands. If an Ethernet interface is placed in the link-up status before all required commands are executed, communication will not be as expected. For this reason, we recommend that you first shut down the Ethernet interface, and then release the interface from the shutdown status after configuration has been completed.
Command examples
-
(config)# interface gigabitethernet 1/0/10
Switches to the Ethernet interface 1/0/10 configuration mode.
-
(config-if)# shutdown
Shuts down the Ethernet interface.
-
(config-if)# *****
Configures the Ethernet interfaces.
-
(config-if)# no shutdown
Releases the Ethernet interface from the shutdown status.
(2) Shutdown of the interface
To shut down the Ethernet interface, enter the applicable Ethernet interface configuration mode and execute shutdown command. Shut down Ethernet if it is not used.
You can also use the operation-command inactivate to terminate Ethernet operation. Note that if a switch is deactivated by using this command is restarted, the status of the Ethernet interface reverts to active. However, if a switch that has been shut down is restarted, its status remains disabled. To change the status from disabled to active, you must release the Ethernet interface from the shutdown status by using no shutdown to configure the interface.
