The show lldp neighborscommand shows information about LLDP neighbors. The iDRAC in the PowerEdge MX compute sled produces LLDP topology packets. These packets contain specific information that the SmartFabric Services engine uses to determine the physical network topology, regardless of whether a switch is in Full Switch or SmartFabric mode.
When viewing the LLDP neighbors, the output shows the iDRAC MAC address in addition to the NIC MAC address of the respective mezzanine card.
