4.1.7 SNMP
The ECO-DC clock supports SNMP version 2c notifications and parameter reading and
setting by means of SNMP GET and SET commands. This allows to integrate the clock
to a network management system. The ECO-DC (SNMP agent) can send alarm
notifications and alive notifications to a SNMP manager. The IP address of the SNMP
manager can be provided to the clock by DHCP, Telnet, SNMP or the MOBA-NMS.
The structure of supported parameters is defined in a MIB file (refer to document TE-
800728 or BE-800793 for details). In addition the clock supports
the “system” node
parameters defined by MIB-2 (RFC-1213)
Alarm notifications are asynchronous messages and are used to inform the manager
about the appearance / disappearance of alarms.
Alive notifications are sent out periodically to report availability and state of the clock.
The interval time can be configured.
SNMP community strings:
read community
romobatime
read / write community
rwmobatime
notification (trap) community
trapmobatime
4.2
Multicast mode
The clock is synchronized to UTC (Universal Time Coordinated) from a NTP server.
The clock receives NTP multicast packets transmitted by the NTP server in a specified
time cycle. This type of synchronization requires no clock’s own IP address and is
therefore suitable for an easy commissioning of the large systems of slave clocks.
Further this mode supports monitoring and parameter configuration by means of
MOBA-NMS software.
For supervision and configuration with MOBA-NMS the multicast group address can be
used or the multicast group address having last octet cleared to zero.
The Multicast operating mode signifies only a minimum amount of configuration work
for a network administrator.
It is necessary to set appropriate time-zone for correct displaying of local time and date
– see the chapter 6 for details.
