Trap Configuration
The "send traps" function can be disabled individually here.
SNMP Trap
Connection Test
Once the "send traps" function has been activated and the trap manager has been defined
using the IP addresses, test traps can now be sent using "Execute" to test the
communication path from the switch to the trap receiver.

General information about SNTP
SNTP (Simple Network Time Protocol) is defined in RFC 4330 (SNTP clients in automation
technology) and is used to synchronize the internal system time with any NTP server, which
represents the "timer", i.e., the universal time. The aim is to synchronize all the components
in a network with the universal time and to thus create a uniform time base.
Time synchronization provides valuable assistance when evaluating error and event logs,
as the use of time synchronization in various network components enables events to be
assigned and analyzed more easily.
Clients should therefore only be used at the most extreme points of an NTP network. Time
synchronization is carried out at fixed synchronization intervals known as polling intervals.
The client receives a correction time by means of an SNTP server, with the packet runtime
for messages between the client and server being integrated in the time calculation in the
client. The local system time of the client is thus constantly corrected. Synchronization in the
NTP is carried out in Universal Time Coordinated (UTC) format.
The current system time is displayed as Universal Time Coordinates (UTCs). This means
that the displayed system time corresponds to Greenwich Mean Time. The system time and
the "UTC Offset" provide the current local time.
The switch supports the use of the SNTP protocol except in client mode, i.e., switches or
other network components only ever receive a time from a time server, but do not transmit
their own times.
