Link Loss Carry Forward (LLCF)*

The Radiance 10Mbps single interface line cards incorporate an LLCF function for troubleshooting a remote connection. When LLCF is enabled, the FL and TP ports do not transmit a link signal until they receive a link signal from the opposite port.

The diagram below shows a typical network configuration with a good link status using Radiance line cards for remote connectivity. Note that LLCF is enabled as indicated in the diagram.

If the connection breaks, the line card carries that link loss forward to the switch/hub which generates a trap to the management station. The administrator can then determine the source of the problem.

Important: When connecting a Radiance line card with LLCF enabled to an auto- negotiating device, force both sides of the configuration to 10Mbps and either full or half duplex. This allows the card to immediately see link pulses and start passing data.

* Line cards are shipped with LLCF disabled (OFF).
