Syslog server

As explained in Acing the CCNA Exam: Volume 2 Advanced Networking and Security

A Syslog server is a service that receives and stores Syslog messages from networked devices for centralized review and correlation.

A Syslog server centrally receives and stores messages from network devices, preserving a historical record for review, troubleshooting, and event correlation. section 7.1.3 section 7.0

Configure Cisco IOS devices to send messages to a server by:

  • Specifying the server address with logging host ip-address. section 7.3
  • Controlling messages sent to the server with logging trap. section 7.3
  • Using UDP port 514 for standard Syslog or TCP port 6514 for Syslog over TLS. section 7.3

Centralized device logging

A router can send events such as interface-state changes, login successes, and configuration changes to a centralized Syslog server while also displaying or buffering them locally. section 7.1

How Acing the CCNA Exam: Volume 2 Advanced Networking and Security covers it

How deep it goes
Explains server configuration, transport ports, and local logging alternatives, but does not detail server software administration.
Examples
Uses interface-state changes, login successes, configuration changes, and a four-destination router logging diagram.
What it assumes
Assumes basic Cisco IOS command-line familiarity while defining local buffers, VTY logging, server logging, and message destinations.
What you can do after
Operate/configure Cisco IOS devices to forward Syslog messages to a centralized server and select standard or TLS transport expectations.
How it connects
Connects Syslog with Cisco IOS logging destinations, logging buffers, severity levels, and SNMP.
