cnMaestro 3.1.0 (Cloud)


This document highlights new features and significant updates in cnMaestro Cloud.

Important: Web Browser

Restart your browser (or clear the browser cache with a hard reload) if you are having UI problems with the 3.1.0 version.

Wireless Client Application Visibility x2

A dedicated page provides insight into the applications accessed by a Wi-Fi Client. This is only supported for Enterprise Wi-Fi 6 Access Points. The feature must be enabled in the AP Group, so the Access Points collect the application data and forward to cnMaestro.


Applications View

The Application page provides aggregate and time-series application details.


Wireless Client Dashboard and Performance x2

Wireless Client Dashboard and Performance pages improve insight into Client activity. This feature is accessed by clicking any Client (Clients > Wireless Clients) at the System, Network, Site, or Wi-Fi AP levels.

Wireless Clients Table

The Wireless Clients Table is presented below.


Wireless Client Dashboard and Performance Views

The Client Dashboard provides application and runtime details on the Clients. The Performance page (not shown) displays key performance parameters over time.


CBRS Co-Existence for CommScope and Federated Wireless

Support is added for CBRS Co-Existence using CommScope or Federated Wireless SAS. This support is already available for Google SAS users.

For CommScope and Federate Wireless, a “Merge User ID” option is displayed when importing a new sector. The default behavior (when set to “yes”) results in the tool sending CBRS registration requests with the SAS User ID prepended to the Sector ID and Spectrum Reuse ID. This allows the SAS to distinguish between operators (if both operators pick the same Reuse ID). In most cases, operators will want the default behavior.

See the Cambium 20.3 PMP Training Course on the Cambium Networks Learning site for more information. It details cases where an operator might want to set this to “no”.


Federated Wireless Enhancements

Federated Wireless operators will see the following additions to the Spectrum Inquiry Response pop-up GUI.

A second view of the bar graph, showing channel sorting by ranking.

A timer near the bottom of the pop-up GUI, which counts down to the next CPAS cycle, guiding operators to wait until the timer expires to obtain a newly sorted spectrum inquiry response, before making the final decision channel selections and pressing ahead with grant requests.

See the CBRS Consolidated Procedures Guide for more details.

Other CBRS Enhancements

The addition and countdown timer shown above will be seen for Google and Federated Wireless operators.

Wi-Fi AP Configuration Updates and Bulk Overrides x2

The Wi-Fi AP Configuration flow has been simplified, and Bulk Overrides are added to efficiently update values across many APs.

Primary Configuration Page

The simplified Configuration page is presented below. It is now used to filter devices.


AP Group/Template Selection and Bulk Overrides Page x2

A subsequent update page supports Bulk Overrides applied to selected devices.


Wireless Clients Report x2

A new report type is added for Wireless Clients that provides an aggregate view of Client activity within a period. Report generation can be scheduled and downloaded in CSV format from the Administration > Jobs > Reports page.


Note the previous Client Report was a Session Report, which detailed statistics for each Client connection. This has been moved to the Client Dashboard as Roaming History.

Guest Access Login Events Report x2

A new report type is added for Guest Access Login Events. Report generation can be scheduled and downloaded in CSV format from the Administration > Jobs > Reports page.


Enhanced Packet Capture for Enterprise Wi-Fi APs

The existing Packet Capture tool is enhanced to create a packet capture file (with a ‘.pcap’ extension) that can be downloaded. It allows packet capture on a single interface or simultaneously on multiple interfaces. This feature is supported for Enterprise Wi-Fi APs running software version 6.4 or higher.


SDR Moved to Essentials

The Software Defined Radios (SDR) support for XV3-8 Wi-Fi APs is now an Essentials feature.


cnArcher Installation Summary x2

The cnArcher Installation Summary is available at Network Services > cnArcher Installation Summary. It is only supported by PMP SMs, and the cnArcher mobile application version must be 1.6.37 or higher.

cnArcher is used to install PMP Subscriber Modules (SMs), ePMP SMs, and cnRanger SMs. The Installation Summary provides an overview of the data collected by cnArcher during the installation process.

A list of PMP installations is presented below.


Details are captured and displayed for each install, including pictures taken at the site.

Map Enhancements

The MAP view is moved to the side tabs to provide better access.


API Updates x2

The Swagger documentation for the updated RESTful API is found at: cnMaestro - RESTful API.

Big thank you for the Applications View.
My customers who migrated from Aerohive have been pining for this functionality for so long.

Is application view available in cnm on premises

When I cambium considering an update on cnm on premises to give admission the ability to change cnm ID.

Whenever a device is on boarded to on premises server. It indicates that it is connected to cnmaestro onpremise instead of a customised name. And many of our clients don’t like it


Yes. Application visibility will be available in cnMaestro On-Premises release - 3.1.0 tracking towards mid of Dec.
Also, On-Premises release - 3.1.0 will contain the fix to show Cambium ID learnt from the Anchor account instead of showing connected to cnmaestro_on_premises.


I have such a strange impression that after updating to version 3.1, the real number of users who logged in on the device during the day does not show. Despite 6 users who logged in to the hotspot, cnmaestro still shows the message that there were 0 users in the last 24 hours?
Where is the mistake ?

Hmmm maybe is mistake :wink:
