Discovery & Monitoring Troubleshooting Capstone

Bundle lab · $29.99

Troubleshoot a pre-broken monitoring deployment on a single shared management LAN. R1 is already configured for discovery and monitoring, but the NMS receives no syslog or SNMP traps from R1. Diagnose with show commands and correct the two seeded faults: wrong syslog target and missing SNMP trap generation. Deterministic, no-routing, single-subnet design for CML Free (5 nodes).

Learning objectives

• Use show logging and show snmp commands to isolate monitoring-plane issues.
• Correct a mispointed syslog destination deterministically on IOS.
• Enable SNMP trap generation and confirm trap targets on IOS.
• Validate discovery protocols (CDP/LLDP) and DNS client settings without relying on runtime states.

Troubleshooting focus

• Symptom-driven diagnosis: No logs received by NMS often indicates wrong destination IP, transport reachability, or disabled logging/trap generation.
• Differentiate configuration-state problems (deterministic) from runtime-state absence (e.g., show cdp neighbors) that is not graded.
