"Access your switch management page"
In the Loopback Detection table, select one of the Loopback Detection State choices
from the pull down menu:
Ignore: This parameter indicates that the setting in the All row do not apply to the
Loopback Detection State field. In other words, each port is set individually.
• Enabled: This selection enables the Loopback Detection feature for each port.
This state must be enabled along with the State field at the top of the page
before this feature can be active on the selected port.
•
Disabled: This selection disables the Loopback Detection feature on the
selected port.
• Note: In the All row when you select Enable or Disable instead of Ignore, the
selection applies to all of the Switch ports.
Next to each entry modified, under the Action column, click Apply to save the changes.
4. Click Save Settings to Flash (menu).
5. Click Save Settings to Flash (button), then click OK.
Note: This step saves all configuration changes to the NV-RAM to ensure that if the
switch is rebooted or power cycled, the configuration changes will still be applied.
