LLDP Configuration Notes and Considerations

  • LLDP is supported on Ethernet interfaces only.
  • Cisco Discovery Protocol (CDP) and RUCKUS Discovery Protocol (FDP) run independently of LLDP. Therefore, these discovery protocols can run simultaneously on the same device.
  • By default, the RUCKUS device limits the number of neighbors per port to four, and staggers the transmission of LLDP packets on different ports, in order to minimize any high-usage spikes to the CPU.
  • Ports that are in blocking mode (spanning tree) can still receive LLDP packets from a forwarding port.
  • Auto-negotiation status indicates what is being advertised by the port for 802.3 auto-negotiation.
