5.1.4 Setting network parameters over autoconfiguration (SLAAC)
IP clock mode must be set to IPv6 mode ( n1: 0/2 ). The NEt MENU item n10 must be set to value 1 .
The network parameters are automatically retrieved from the DHCPv6 server.
The following SLAAC options can be processed:
[3]
prefix info
[5] MTU
[24] route info
[25] RDNSS
The network administrator must set the SLAAC options accordingly.
5.1.5 SNMP
The 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 digital 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, web interface, 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 alarm.
Alive notifications are sent out periodically to report availability and state of the clock. The interval
time can be configured.

5.2 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.
