Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) Counters showing frames sent on a port but no frames received on that port indicates an active link with a device that either has LLDP disabled on the link or is not LLDPaware. Figure 13-22. Example of a Global LLDP Statistics Display Figure 13-23. Example of a Per-Port LLDP Statistics Display LLDP Operating Notes Neighbor Maximum. The neighbors table in the switch supports as many neighbors as there are ports on the switch. The switch can support multiple neighbors connected through a hub on a given port, but if the switch neighbor maximum is reached, advertisements from additional neighbors on the same or other ports will not be stored in the neighbors table unless some existing neighbors time-out or are removed. LLDP Packet Forwarding: An 802.1D-compliant switch does not forward LLDP packets, regardless of whether LLDP is globally enabled or disabled on the switch. 13-75
