Caution Before enabling a feature on the Ethernet ma nagement port, make sure that the feature is supported. If
you try to configure an unsupported feature on the Ethernet Management port, the feature might not work
properly, and the switch might fail.
Configuring the Ethernet Management Port
To specify the Ethernet management port in the CLI, enter fastethernet0.
To disable the port, use the shutdown interface configuration command. To enable the port, use the no
shutdown interface configuration command.
To find out the link status to the PC, you can monitor the LED for the Ethernet management port. The
LED is green (on) when the link is active, and the LED is off when the link is down. The LED is amber
when there is a POST failure.
To display the link status, use the show interfaces fastethernet 0 privileged EXEC command.
TFTP and the Ethernet Management Port
Use the commands in Table 12-2 when using TFTP to download or upload a configuration file to the boot
loader.
