Overview

The L2 Discovery Module for LLDP provides a function to read neighbor devices information of LLDP held by network equipment from Zabbix using SNMP.

Features

•  Zabbix can monitor neighbor devices information of LLDP (data link layer)
•  Templates automatically generate items according to collectable information
•  Host macros can forcibly overwrite neighbor devices information

How to use

Distribution packages include loadable modules and monitoring templates.

Loadable modules are used by incorporating them into Zabbix Server or Zabbix Proxy.

The monitoring template is imported from Zabbix Fronetnd and linked to the host that monitors the LLDP information.

Limitations

•  It works only on devices that support LLDP and can refer to LLDP information with SNMP
•  Items are created for each entry number of LLDP, so past connection information can not be retained
•  Loadable modules do not work with Zabbix Agent
•  Does not support SNMPv3
