Chapter 32: Event Log
484
Overview
A managed switch is a complex piece of computer equipment that
includes both hardware and software components. Multiple software
features operate simultaneously, inter-operating with each other and
processing large amounts of network traffic. It is often difficult to determine
exactly what is happening when a switch appears not to be operating
normally, or what happened when a problem occurred.
The operation of the switch can be monitored by viewing the event
messages generated by the device. These events and the vital information
about system activity that they provide can help you identify and solve
system problems.
The events are stored by the switch in an event log, in temporary memory.
The events in the log are discarded whenever you reset or power cycle the
switch.
The event messages include the following information:
 The time and date of the event
 The severity of the event
 The management module that generated the event
 An event description
