Introduction

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.

All Vutlan monitoring systems support SNMP Trap.

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. the amount of elements:".

How to create an SNMP Trap

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

Parameter	Description

Parameter	Description
Name	The name of the element in the system
SNMP server	Name or SNMP server IP address (192.168.1.10)
SNMP port	SNMP port (usually 162).
Version	Version (v1, v2c or v3)
Community	Community name (public)
USM user	User 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 algorithm	the algorithm of authorization for protocol v3 with security level "priv" and "auth".
Auth password	the password of authorization for protocol v3 with security level "priv" and "auth".
Private algorithm	the algorithm of authorization for protocol v3 with security level "priv".
A private password	the password of authorization for protocol v3 with security level "priv".

Question

Answer

Do I need to configure 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:
