Enabling and disabling remote fault notification
RFN configures the transmit port to notify the remote port whenever the fiber cable is either physically disconnected or has failed.
RFN is set to auto-gig by default. To disable RFN, use the following command.
device(config)# interface ethernet 1/1/1 device(config-if-e1000-1/1/1)# gig-default neg-off
To re-enable RFN, use the following command.
device(config)# interface ethernet 1/1/1 device(config-if-e1000-1/1/1)# gig-default auto-gig
Syntax: [no] gig-default { neg-full-auto | neg-off | auto-gig }
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.
For more information about the parameters supported with the gig-default command, see "Changing the Gbps fiber negotiation mode" section in the Ruckus FastIron Monitoring Configuration Guide .
