The network administrator must set the SLAAC options on the server
accordingly.
Assigned parameters can be checked in the P25 submenu
11.1.6 SNMP
The DC clock supports SNMP version 2c notifications and parameter reading
and setting by means of SNMP GET and SET commands. This allows
integrating the clock to a network management system. The DC clock (SNMP
agent) can send alarm 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 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:
notification (trap) community
11.2 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 9 for details.
Default network parameters:
IPv4 multicast group address
IPv4 multicast config address
IPv6 multicast group address
FF38::EFC0:3601 (FF38::239.192.54.1)
IPv6 multicast config address
FF38::EFC0:3600
(FF38::239.192.54.0)
configuration port number
time zone client port number
The menu item P19 must be set to value 1. See chapter 4.2.7 for setting the IPv4
multicast group address in the item P23 submenu.
