Remote Fault Notification on 1Gbps fiber connections
NOTE
Remote fault notification (RFN) is only available for 1 Gbps Ethernet Fiber ports. It is not available for
10/100 ports and Gbps Ethernet Copper ports. This feature is not available on ICX 6430and ICX 6450
devices.
For fiber-optic connections, you can optionally configure a transmit port to notify the receive port on the
remote device whenever the transmit port becomes disabled.
When you enable this feature, the transmit port notifies the remote port whenever the fiber cable is
either physically disconnected or has failed. When this occurs and the feature is enabled, the device
disables the link and turns OFF both LEDs associated with the ports.
By default, RFN is enabled.
You can configure RFN as follows:
• Globally, on the entire device
• On a trunk group
• On an individual interface
