The link-detect enable command enables LAD on an interface.
The undo link-detect enable command disables LAD on an interface.
By default, LAD is enabled on all interfaces.

Usage Scenario
An LAD-enabled interface can encapsulate local information into an LAD packet and send it to a neighbor. After receiving an LAD packet from the neighbor, the local interface can save local information and neighbor information carried in the packet to the local MIB. The local and neighbor information is recorded as one entry.
Before using LAD to discover neighbors, run the link-detect enable to enable LAD on an interface.Follow-up Procedure
Run the link detect command to enable a device to send LAD packets to neighbors.
