Chapter 12: Event Log
Section II: Advanced Features 204
Event Log Overview
A managed switch is a complex piece of computer equipment that
includes both hardware and software. Multiple software features
operate simultaneously, interoperating 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 the problem occurred.
A network manager’s major task is to monitor the system functions and
to deal with problems as they arise. The event log provides vital
information about system activity on the AT-8400 switch that helps you
identify and solve system problems. The event log includes the
following information:
❑ the time and date of an event
❑ the severity of an event
❑ the AT-S60 software module that generated the event
❑ a description of the event
The event log can store up to 4,000 entries. All events are purged from
the log when the switch is reset or power cycled. However, you can save
an event log by using the S-Save option. See Saving the Event Log on
page 212.
Allied Telesyn recommends that you set the switch’s date and time if you
intend to use the event log. Otherwise, the switch does not log the
entries with the correct date and time. For instructions, refer to Setting
the System Time on page 59.
Note
The event log, even when disabled, logs all AT-S60 initialization
events that occur when the switch is reset or power cycled. Any
switch events that occur after AT-S60 initialization are entered into
the log only if you enable the event log. The default setting for the
event log is disabled.
