LA-210 Ver. 1.5 Handling Alarms and Traps 6-21
6.3 Handling Alarms and Traps
LA-210 maintains a log file, which can hold up to 1,000 system messages. All
events are time-stamped.
Traps that are the result of events that were already reported by a different trap
may not be repeated. For example, LOC traps will not be sent if the physical layer
trap, such as LOS, was sent and the physical layer problem still exists.
The events are layered hierarchically, for example physical layer events/traps for
Loop Attenuation and SNR Margin are threshold triggered, so that an event/trap
is sent only if the threshold was exceeded.
Threshold can be configured for up to 8000 events per second.
The Event Log file contents can be viewed via an ASCII control terminal or a
Network Management Station (NMS).
The contents can be cleared at any time.
All traps (alarm and system) can be masked per manager, as described in
Chapter 4.
Displaying the Event Log File
LA-210 has an integrated NTP client. The NTP client is used as a means to receive
the date and time from the network. When the NTP server is properly configured
and accessible, the device displays the real date and time as was received from
the NTP server, instead of the system uptime, which is the default state.
When the real date and time are not available, the log file messages are recorded
with the date 00-00-0000 and system uptime. Once the NTP server becomes
available, all messages (including those already received) appear with the real
date and time.
³ To access the Event Log file:
1. From the System menu (Monitoring > System), select Event Log.
The Event Log screen appears as illustrated in
Figure 6-21 and
Figure 6-22 .
Table 6-16 and Table 6-17 present the event types that appear in the
Event Log file.
2. Use the arrow keys to scroll the event list up and down, left and right.
