Troubleshooting Tools
Cisco routers provide useful commands for diagnosing network problems. Commands such as show ip interface brief, show interfaces, and show ip route allow checking the operational status of interfaces and routing tables. Tools like ping and traceroute test connectivity, while logs and debug commands help detect packet loss or configuration errors.
Symptoms, Causes, and Diagnosis
Common network symptoms include high latency, packet loss, or total disconnection. These can result from incorrect router configurations, misapplied ACLs, routing protocol errors, or hardware failures. Identifying and isolating the root cause requires analyzing each network layer and verifying configurations step by step.
