LLDP/4/TOOMANYNEIGHBORS
Possible Causes
In general, the topology does not generate the event that the number of neighbors exceeds the maximum value (the maximum number of global neighbors is 4096, and the maximum number of neighbors under a port is 256). The event happens because the peer device connected to the current device enables the LLDP transparent transmission function so that a large number of non-direct connection devices become the neighbors of the current device.
