SNMP Traps port management

Overview

The SNMP Trap listener port management capability allows you to configure and control how SNMP traps are received from devices that are added for monitoring. This includes setting up trap destination ports, enabling or disabling the SNMP Trap listener ports, editing port values, and managing SNMP credentials for various protocol levels (V1, V2c, V3). This helps maintain secure and accurate log ingestion from SNMP-supported devices.

Configuring a device to send SNMP traps

1. In the product console, navigate to the Settings tab and click on Listener ports listed under System Settings as shown in the below image.

   

2. You will be taken to the Listener Ports segment. You can find the fields listed under Manage SNMP Traps Listener Port, as highlighted below.

   

3. In your device settings configuration, set the trap destination host address to the IP address or the hostname of the corresponding product's server.
4. Set the trap destination port to 162 or to the SNMP port configured in the product—Log360, EventLog Analyzer, and Log360 Cloud.
5. Specify the SNMP credentials that are already configured.
6. Save the configuration.
