Abstract

In this thesis, the implementation characteristics of the LLDP protocol on network devices from various manufacturers are analyzed. The operating principles of the LLDP protocol based on the IEEE 802.1AB standard and the differences in vendor devices are examined. The research analyzes methods for collecting LLDP data via SNMP. As a result, proposals were developed for identifying and resolving compatibility issues between devices from different vendors.
