Episode 123: Logging Essentials — Syslog, Auditing, and Interface Statistics

Logs are a goldmine of operational insight—and in this episode, we explain how to access, interpret, and act on the information they provide. You’ll learn about Syslog, the standard logging protocol used by most network devices, and how to configure Syslog levels to capture just the right amount of detail. We also discuss the role of centralized logging servers and how they support forensic analysis, trend detection, and compliance.Beyond Syslog, we examine interface statistics and event auditing on routers, switches, and firewalls. Topics like up/down events, input/output errors, CRC counts, and administrative actions are broken down into understandable units. By the end, you’ll be prepared to read and respond to logs as a regular part of network maintenance and troubleshooting.
