Discovery & Monitoring Troubleshooting Capstone
Advanced discovery and monitoring capstone, run as a fault hunt. The NMS has stopped seeing this site: neighbours are missing from the topology map, no traps are arriving, and syslog went quiet — while every device is reachable and pingable. You get symptoms and the required end state — no fault list. Faults span both routers and the switch they all peer through, and more than one of them leaves the monitoring configuration looking complete.
