There's no direct limit of SNMP Trap elements in the system.

But there's a limit for overall elements in the system. Please use the table from "Comparison chart: Master modules", "Comparison chart: PDUs", horizontal field "Max. amount of elements:".


When the Vutlan monitoring device detects an error or a change, the device will send a notification to one or more trap receivers onto a specified IP address. Traps are only sent using logic schemes or group notifications. For example, if a logic scheme is activated, the trap will be sent to a trap receiver.

To create a notification via SNMP trap you have to specify the following parameters:

ParameterDescription
NameThe name of the element in the system
SNMP serverName or SNMP server IP address (192.168.1.10)
SNMP portSNMP port (usually 162).
VersionVersion (v1, v2c or v3)
CommunityCommunity name (public)
USM userUser name for protocol v3
Security level

Security level for protocol v3, mobile version.

"noauth" - no authorization, only user name needed;

"auth" - with authorization, need to fill in "Auth algorithm" and "Auth password";

"priv" - with authorization and data encryption, need to fill in "Auth algorithm", "Auth password", "Private algorithm" and "Private password";

Auth algorithmthe algorithm of authorization for protocol v3 with security level "priv" and "auth".
Auth passwordthe password of authorization for protocol v3 with security level "priv" and "auth".
Private algorithmthe algorithm of authorization for protocol v3 with security level "priv".
Private passwordthe password of authorization for protocol v3 with security level "priv".

Frequently asked questions

QuestionAnswer
Do I need to config the SNMP trap for each sensor?

You can configure an individual SNMP trap for separate sensors.

But it is best to `Group` of sensors. See the links below:
