Chapter 8: Overview
 This chapter covers three protocols that a network administrator
can use to monitor the network.
 Syslog, SNMP, and NetFlow are popular protocols with different
strengths and weaknesses. Together, they provide a good toolset
for understanding what is happening on a network.
 The Network Time Protocol is used to synchronize time across
devices, which is especially important when trying to compare log
files from different devices.

Chapter 8: Best Practices
 Prior to teaching Chapter 8, the instructor should complete Chapter
8, “Assessment.”
 Emphasize the value in using network monitoring to not only know
the “health” of your network, but to prevent future problems.
 Inform students that syslog servers are either a free or paid
application and that functional level varies among different servers.
 Remind students that without timestamps, troubleshooting can be
much harder as there is no way to view messages in synchronous
time.
 When discussing NetFlow, examples help students to understand
why it is important. Quality of service (QoS) in an IP Phone and data
network, for example.
