7.5 Alarm configuration
This page is used to enable clock supervision, to define the information to be transmitted and the destination server. One
or more settings can be defined and configured as alarms.
The following information is displayed:
• Enable SNMP
checkbox: enables monitoring of the clock from a SNMP manager.
• Community
: A set of clocks defined by the user. All the clocks on the network must have the same Community
name.
• Enable SNMP Trap
checkbox: If enabled, error messages are sent to the SNMP Manager(s) automatically.
• SNMP Manager 1/2/3
: IP addresses of servers receiving alerts from the clocks. SNMP Manager redundancy
increases the reliability of alerts.
• Synchronisation failure
: This setting is used to detect synchronisation discrepancies with the source master
clock (Sigma type). or the time server (Netsilon type).
Multicast: Alarm triggered when the multicast synchronisation is absent for at least 1hour.
Unicast: Alarm triggered when the unicast synchronisation is absent for 3 times the duration of the poll
(periodicity) and at least 1 hour (allowing for the NTP server maintenance)
• Reboot
: This setting is used to detect a clock reboot.
• Temperature
: This setting is used to warn that the temperature range has been exceeded (variable temperature
range).
• Manipulation
This setting is used to trigger an alert if a setting is changed manually on the clock (using the “S”
and “+” keys).
• Server access
: This setting is used to trigger an alert if a user connects to the web server of the clock.
• Authentication failure
: This setting is used to trigger an alert if a user sends an incorrect ID to the web server
of the clock.
• Periodic Status
: This setting is used to verify that the device is still working correctly (in case alerts are “lost”).
This verification is carried out at a set frequency.
