Link Layer Discovery Protocol (LLDP) is a protocol that allows network managers to troubleshoot and modify network management in multi-vendor environments. LLDP enables a device to advertise its identification, configuration, and capabilities to neighboring devices that will then store the data in a Management Information Base.
This article explains how to view LLDP statistics for each port on the ESW2-550X stackable managed switches.
• ESW2-550X
• ESW2-550X-DC
• v1.2.9.44
Step 1. Log in to the web configuration utility of the switch and choose Administration > Discovery - LLDP > LLDP Statistics. The LLDP Statistics page opens:
Step 2. Choose the desired interface from the Interface Type equals to drop-down list. Click Go.
The following information is displayed for each port:
• Interface — The identifier of the interface.
• Tx Frames Total — The total number of transmitted frames.
• Rx Frames — Received frames.
– Total — The total number of received frames.
– Discarded — The total number of received frames that were discarded..
– Errors — The total number of received frames with errors.
• Rx TLVs — Type-Length-Values of received frames.
– Discarded — The total number of received TLVs that were discarded.
– Unrecognized — The total number of received TLVs that were unrecognized by the system.
• Neighbor's Information Deletion Count — The number of times the neighbor information has aged-out on a particular interface.
