Configuring a SHIELD System for SNMP

What is SNMP?

SNMP (Simple Network Management Protocol) is protocol for monitoring and managing devices on IP networks. It enables authorized users to collect information about device status and active alarms, and may also provide remote command capabilities. The SNMP architecture operates with an “agent” on the device and a “manager” platform configured to send and receive messages with registered devices. An organization may use an SNMP management platform to centrally aggregate health monitoring and system control across many locations, varied device types, and different device manufacturers.

SNMP with SHIELD EXTEND and SHIELD SOLO

With the introduction of SHIELD MU (Management Unit) version 11 firmware, the SHIELD EXTEND and SHIELD SOLO products now support SNMP. Configuring and enabling the SNMP agent for SHIELD is performed in the WAVE Portal once the system is commissioned and calibrated.

SHIELD SNMP Networking Requirements

The MU has a single network port, labeled WAN. The primary function of this interface is to communicate with the WAVE Cloud. When the SNMP agent is enabled, it is also used for SNMP messages. If SNMP traffic will be routed locally or over a VPN, then outbound traffic to the WAVE Cloud must also be permitted, either from the local gateway or via hairpin at the VPN server. In addition to the connectivity requirements of your chosen SNMP management platform, the following outbound connections are required by SHIELD:

• HTTPS outbound to iot.cel-fi.com:443
• HTTPS outbound to waveapi.cel-fi.com:443
• HTTPS outbound to nextivitystorageqa.blob.core.windows.net:443
• HTTPS outbound to nextivityiothubqa.azure-devices.net:443
• NTP outbound to ntp.cel-fi.com:123  (recommended)
• Relevant DNS resolution via the default gateway or per DHCP-assigned server

SNMP Features Available

The SNMP agent on SHIELD EXTEND and SHIELD SOLO includes:

• Robust set of operating status OIDs
• Alarm indicator OIDs
• Alarm traps
• Four commands: Shutdown, Startup, Reboot, Update Software
• Command traps

The agent supports SNMP versions 2c and 3. Version 3 is strongly recommended.

Enabling SNMP on SHIELD

Once the SHIELD system is commissioned on the WAVE Portal and calibrated on site using the WAVE PRO App, it is ready to be configured for SNMP by following these steps:

1. Go to the system’s page in the WAVE Portal.
2. Confirm the Server Connection status is Active.
3. Click on the MU entry in the Assets list.
4. Select Start SNMP from the Options menu at the top-right of the page.
   (You will not see this option if your MU has not yet been updated to version 11 or later.)

5. Fill in the form based on the requirements of your particular SNMP management platform and click Submit.

6. The confirmation dialog confirms that the SNMP agent is enabled. If changes are needed, select Options > Disable SNMP and repeat the process. SNMP credentials are not saved within the WAVE platform.
7. As needed: Download the ZIP file linked below. Extract and load into your SNMP manager the MIB file contained within.
