Enables Link Fault Signaling (LFS) between 10 Gbps Ethernet devices.

link-fault-signal
no link-fault-signal

LFS is disabled by default on all RUCKUS FastIron devices.

Interface configuration mode

When configured on a RUCKUS 10 Gbps Ethernet port, the port can detect and report fault conditions on transmit and receive ports. RUCKUS recommends enabling LFS on both ends of a link.

Enable LFS on any device prior to connecting the device to FastIron platforms. Any connecting device must have LFS currently enabled to ensure interoperability. When LFS is enabled on an interface, syslog messages are generated when the link goes up or down, or when the TX or RX fiber is removed from one or both sides of the link that has LFS enabled.

You can view the status of an LFS-enabled link using the show interface command.

The no form of the command disables the Link Fault Signaling (LFS).

The following example enables LFS. 

device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# link-fault-signal
