An Overview of the syslog Protocol

Chapter Description

This chapter presents an overview of the syslog protocol and shows you how to deploy an end-to-end syslog system. You'll learn about the syslog architecture as well as the issues in deploying syslog servers in Linux and Windows OSs with a focus on their relevance in a Cisco environment.

Summary

The topics covered in this chapter prepare the Netadmin for deploying a centralized logging facility to collect syslog messages from all the network devices. The Netadmins should be able to perform the following syslog-related tasks:

  • Deploy a Linux-based syslog server to support Cisco devices
  • Deploy a Microsoft Windows–based syslog server
  • Centrally log events and alarms generated by Cisco IOS–based routers and switches
  • Centrally log events and alarms generated by Cisco CatOS–based switches
  • Centrally log events and alarms generated by Cisco PIX Firewalls
  • Centrally log events and alarms generated by Cisco VPN 3000 Series Concentrators.

Table 4-14 provides a list of all the tools discussed in this chapter. The table also provides the source of documentation for each tool.
