METHOD AND MANAGEMENT NODE IN A COMMUNICATION NETWORK, FOR SUPPORTING MANAGEMENT OF NETWORK NODES BASED ON LLDP MESSAGES

摘要

Embodiments support management of network nodes (120-123; 124-127) comprised in a communication network (100). A management node (130; 131) receives (501a-b; 601), from at least some of said network nodes (120, 121), LLDP information based on one or more LLDP messages received from neighboring network nodes (120-124) that are neighbouring said at least some network nodes (120, 121). The LLDP information comprises security status information regarding said neighbouring network nodes (120-124), indicating if a neighbouring network node (120) has been verified to be authentic and indicates if the neighbouring network node (120) has been verified to be not authentic.
