Feature Flag (Y) — The feature is available to select EFT customers by request. Please contact your Cisco support representative for assistance.
Caveats/Known Issues
- From January 12, 2022, API Keys will no longer be available for North Bound APIs. Users should refer to the DevNet documentation for instructions on using login credentials to get the access token.
Limitations
- To ensure NAT works smoothly, it's best to avoid using source ports below 1024 and the port 1900. If not, there's a risk that the IPSec tunnel between the IXM and the cloud environment may fail to connect due to blocked traffic.
- If sensors are onboarded but haven't sent any data, their DevEUI won't appear in the MQTT integration's topic path.

Sensor troubleshooting |
Sensor troubleshooting UI uses a fixed value of one day to calculate un-reachability and does not use the configured template value for the sensor. |
Alert Dashboard |
The widget in alert dashboard is not auto refreshed although the alert table below is auto refreshed. So, if the user is on the alert dashboard page and there are new alerts added/cleared, then there will be a discrepancy in the alert count between the widget and the table below. |

New features
Geofences can be used to track the location of GPS-enabled sensors and associated assets in relation to an area on a map. This allows you to create a virtual perimeter for your real-world geographic area, and receive information as sensors and associated assets enter or leave that area. Learn more.
In future releases, you will be able to apply rules or trigger alerts based on where a sensor is in relation to that "geofence".
Note: Geofencing is available to select EFT customers by request. Please contact your Cisco support representative for assistance.
The name and location of a Sensor can now be edited using UI. Learn more.
Limitations
- The Message Inspector is currently beta functionality and not fully implemented. Cisco will enhance the Message Inspector in future releases and make it generally available.
- Some Cisco sensors may have QR codes that are too small to scan with the mobile application. We advise installers to either scan the full-size QR code on the packaging or enter the DevEUI manually in the mobile application.
- Only public network devices are supported currently.
- Customers need to ensure either of the following:
- Each IXM gets a unique public IP when communicating with the IoT Operations Dashboard (non-NAT deployments scenario).
- If two or more IXM are behind the same NAT, then the deployment sequence of IXMs should be staggered i.e. please maintain a gap of 10 minutes between two IXM starts.
