Configure SNMP trap ports

During device discovery, EcoStruxure IT Gateway automatically attempts to register itself as a trap receiver with APC and Schneider Electric SNMP devices with a Network Management Card (NMC) on port 1062.

In Gateway 1.10 and newer, you can configure additional SNMP ports in the Settings > Advanced > SNMP trap ports option. 

Tip: Running an older Gateway version? See How to update your Gateway software

Allowed ports are 0 - 65535. The default system trap port 1062 cannot be changed. The configurable port list contains port 162 by default to support the default for most third party devices.

The Gateway listens for SNMPv1 traps only.

Note: Make sure you adjust firewall rules to allow for any additional ports you add in the Gateway.

You do not have to restart the Gateway after changing the list of available ports.

Third party devices

To allow the Gateway to receive traps from third party devices, or Schneider Electric devices without an NMC - in other words, devices where the Gateway cannot automatically register itself as a trap receiver - you must manually configure each device with these trap receiver settings:

• NMS IP address/Host name: Your EcoStruxure IT Gateway IP address
• Version: SNMPv1
• Port:
  • Gateway version 1.9 or earlier: Port 1062*
  • Gateway version 1.10 or later:  Port 1062, 162, or a port you specify in the Settings > Advanced > SNMP trap ports option
• Community string: public

*Gateway versions 1.9 and earlier required 1062 as the trap port for third party devices.

Some devices may require additional device-specific settings for traps to be sent. Consult the user manual for the device for more information.

When EcoStruxure IT Gateway receives a trap from a device, it immediately polls the alarms that are predefined for the device. It does not process the content of the trap message. It does not poll the sensors immediately, which means that alarms created based on sensor thresholds will not be updated until the next scheduled poll.
