cnMaestro 3.0.4 (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 3.0.4 version.

cnMaestro RESTful API

The cnMaestro RESTful API is now supported for Cloud customers with a cnMaestro X account. The API allows customers to read data and perform operations programmatically using their client applications. The API is supported over HTTPS, and messages are exchanged in JSON format. Modern programming languages have rich support for RESTful interfaces.

cnMaestro API leverages the OAuth 2.0 Client Credentials Grant Type. The Client Credentials Grant is used to obtain an Access Token. Full programming instructions are found in the User Guide. Please refer to Swagger API documentation for details on individual APIs.

E2E Controller

The cnWave Terragraph infrastructure supports E2E (End-to-End) Controllers through two separate deployments:

External E2E Controller: downloaded from Cambium Support Center and installed in a VMware Virtual Machine.

Onboard E2E Controller: integrated into cnWave Devices.

External E2E Controller

The External E2E Controller is onboarded to cnMaestro and is presented as an E2E Network. The graphic below displays the E2E Network Dashboard in cnMaestro.


Onboard E2E Controller

The Onboard E2E controller is hosted on a 60 GHz cnWave device running version 1.0.1-beta5 or later. The E2E Network Dashboard for an Onboard E2E Controller is presented below.

RESTful APIs for External Captive Portal Integration

Enable the “External Portal Post through cnMaestro” feature available at Enterprise WLAN Policy > Guest Access page.

These OAuth 2.0 RESTful APIs support external captive portal integration with Enterprise Wi-Fi APs:

  • /api/v2/ext-portals/login
  • /api/v2/ext-portals/logout


Enhancements to Active Alarms

The following updates have been made to Acknowledged Alarms:

  1. They are no longer included in the Active Alarm count.
  2. They are displayed after Unacknowledged Alarms at the same severity level.
  3. The font of the Active label will be regular instead of bold.

Sorting and filtering support are also added for the Acknowledge column.


Map Enhancements

The following are significant updates to Maps:

  1. The Map display is restructured with a collapsible sidebar that supports configuration and status.
  2. The icons are leaner to optimize real estate. The Tower and Site icons display device count.
  3. Smoother zoom experience on scroll.

Removed Reregistration Map Mode and added a new Link Quality Indicator (PMP).


Miscellaneous UI Improvements

Grid size is retained while moving across different grids within the current UI session. Also, column chooser options are retained for individual grids within the current UI session.

Oh man can’t wait to try RESTful API during the week.
Hopefully we can interact with PPSK’s via the API.

Well good news . RESTful API works decently, haven’t picked up any issues yet.
Can create EPSK’s from PostMan/Ansible though still looking for a way on how to generate QR codes from the dynamically generated passwords and deliver them to user emails.
