Lldp On Mpr-E; Transmitting Nearest Bridge Lldpdus; Default Parameter - Alcatel-Lucent 9500 User Manual

1. The MPT and the LLDP enabled device advertise their chassis/port IDs and system
descriptions along with other information to each other.
2. The devices store the information they learn about each other in local MIB/databases
accessible via SNMP.
3. Network management systems discover the network topology by crawling the NEs
and querying the MIB on each device.
