SNMP#
The clock supports SNMP version 1, version 2c and version 3 for reading and setting parameters using SNMP GET and SET commands. Only SNMP v2c is supported for SNMP trap notification.
SNMP support allows the clock to be integrated into the system for monitoring network elements. The clock (SNMP agent) can send alarms or notifications to the SNMP manager. The IP address of the SNMP manager can be set in the clock via DHCP, web interface, SNMP or MOBA‑NMS.
The supported SNMP protocol version and other necessary parameters for user authentication and communication encryption can be set in the clock via the web interface, SNMP or MOBA‑NMS. The SNMP version can be set in combinations:
v3, v2c, v1
v3, v2c
v3
v2c, v1
The structure of the supported parameters is defined in the MIB file (see document TE‑800728 or BE.800793 for more information, on request). In addition, the clock supports the parameters defined by the “system” node in the MIB‑2 definition (RFC‑1213). Alarm notifications are asynchronous messages and are intended to inform the SNMP manager about the occurrence or disappearance of an alarm. Alive notifications are sent periodically to inform about availability and clock status. The sending interval can be set.
Alarm notifications are asynchronous messages and are intended to inform the SNMP manager about the occurrence or disappearance of an alarm.

SNMPv3#
SNMPv3 includes user authentication and communication encryption. Security is provided using a Security name, Authentication password, and Privacy password. During authorization, communication can be encrypted using MD5 or SHA (SHA‑1), and the actual communication can be encrypted using DES or AES (AES 128). The security level can be configured.
The clock allows you to set up two user profiles with different access rights within SNMPv3. Each user has their own combination of Security name, Authentication password and Privacy password along with the appropriate encryption and access rights, which together form a profile.
