Because WR is Ethernet, a WR-based timing system can benefit from all standard network protocols and tools available in the Ethernet ecosystem. This paper describes the configuration, monitoring and diagnostics of a WR network using standard tools. Using the Simple Network Management Protocol (SNMP), clients can easily monitor with standard monitoring tools like Nagios, Icinga and Grafana e.g. the quality of the data link and synchronization. The former involves e.g. the number of dropped frames; The latter concerns parameters such as the latency of frame distribution and fibre delay compensation. The Link Layer Discovery Protocol (LLDP) allows discovery of the actual topology of a network. Wireshark and PTP Track Hound can intercept and help with analysis of the content of WR frames of live traffic. In order to benefit from time-proven, scalable, standard monitoring solutions, some development was needed in the WR switch and nodes.
