Introduction
This document highlights new features and significant updates in cnMaestro On-Premises. A separate topic lists the fixes and known issues. The text was revised on 4/3/2023 for release 3.2.0-r7.
Note: Upgrading from 3.2.0-r5
The primary updates in 3.2.0-r7 (over 3.2.0-r5) are: CBRS is now fully supported, and there are a couple enhancements for 60 GHz cnWave (detailed below). There are also several CR fixes listed at the end of this document. Outside of these items, upgrading from 3.2.0-r5 to 3.2.0-r7 is optional.
Important: OVA Upgrade
cnMaestro 3.2.0 On-Premises is distributed as an OVA file, which can be installed as a new Virtual Machine or used to update an existing installation running cnMaestro 3.1.0/3.1.1.
Important: System Backup
It is strongly recommended to take a System Backup prior to upgrading to 3.2.0. This can be done in the UI at Administration > Server > Operations. This is required in case you ever want to downgrade back to the previous version.
Important: Cloud Anchor Accounts
All existing cnMaestro On-Premises instances need to attach to an Anchor account before upgrading to cnMaestro 3.2.0.
Important: Minimum Device Versions
cnMaestro 3.2.0 has removed support for TLS 1.0/1.1 as per current security guidelines. Older Cambium devices use these versions by default, and their software should be updated before transitioning to 3.2.0 (else they will lose connectivity). The minimum versions are:
| # | Device Type | Version |
|---|---|---|
| 1 | cnPilot E Series | 3.9-r3 |
| 2 | cnPilot R Series | 4.5 |
| 3 | ePMP | 4.3 |
| 4 | ePMP 1000 Hotspot | Only supports TLS 1.0/1.1 (product is EOL) |
| 5 | PMP | 20.0.1 |
If you cannot upgrade to these versions, read the section Enabling TLS 1.0/TLS 1.1 in the User Guide.
Important: API v1 No Longer Supported
As announced during 3.0.0 release, support for the “v1” API version is removed starting in 3.2.0. More information is available in the API Clients section of the User Guide.
Swagger documentation for the v2 RESTful API is available at:
Note: Activation of 90-Day Free Trial
By default, a 90-day free trial for cnMaestro X is activated if cnMaestro X is selected during upgrade. This ensures customers have sufficient time to purchase cnMaestro X subscriptions, and devices can complete the Cloud sync operation.
Customers creating new 3.2.0 On-Premises instances can request a 90-day free trial at https://www.cambiumnetworks.com/cnmaestro-x/.
Note: Web Browser
Restart your browser (or clear the browser cache with a hard reload) if you are having UI problems with the 3.2.0 version.
Introduction to cnMaestro Subscription Variants
cnMaestro 3.2.0 supports two subscription variants: Essentials and X.
cnMaestro Essentials
This unlicensed, free version of cnMaestro delivers the same experience as the previous cnMaestro, but without the X features.

Cloud Anchor Account
Important: Cloud Anchor Accounts
All existing cnMaestro On-Premises instances need to attach to an Anchor account before upgrading to cnMaestro 3.2.0. All new 3.2.0 On-Premises installations must link to a Cloud Anchor account after installation.
The Cloud Anchor Account exists alongside current NMS Accounts (which host cnMaestro Cloud NMS). The cnMaestro On-Premises instances link to an Anchor account using the Cambium ID and Onboarding Key, both created with the Anchor account. The User Guide details creating an Anchor Account and associating it with one-or-more cnMaestro On-Premises instances.
The Cloud Anchor account serves multiple purposes:
- Manages subscriptions for both cnMaestro Essentials (free) and cnMaestro X (paid).
- Automatically pushes announcements of new device firmware and cnMaestro software images.
- Simplifies CBRS provisioning and billing by aggregating multiple cnMaestro On-Premises instances.
Subscription Management
The Manage Subscriptions > Subscriptions page in the cnMaestro Cloud Anchor account provides a usage summary and a list of pending/active/expired subscriptions across all cnMaestro X On-Premises instances. It aids planning for renewals and the purchase of new subscriptions. The table lists the available subscription tiers; the number of slots used; the status of the subscriptions; the start and end date of the subscriptions; how long the subscriptions are valid; and the EID to which the subscriptions were assigned.
Devices
The Manage Subscriptions > Devices page shows devices mapped to cnMaestro X On-Premises instances. It displays a pie chart with different subscription tiers and a table which lists the devices assigned to subscriptions, including MAC Address, Serial Number, Type, Device Tier, Slot Issued to, Slot Issued by, Subscription Name, Subscription Validity, and Subscription State.
On-Prem Instances
This Manage Subscriptions > On-Prem Instances page lists the Tier Category and the number of Subscriptions per Tier for each On-Premises instance linked to the Anchor Account.
On-Premises Cloud Connectivity
Starting in 3.2.0, On-Premises instances must connect to a Cloud Anchor Account to synchronize devices and subscriptions with Cambium. Two connection models are supported: persistently connected and intermittently connected. It is highly recommended On-Premises instances maintain a persistent connection to their Anchor account.
If a persistent connection is not possible, the On-Premises instance can disconnect provided all device(s) have completed Cloud sync with the Anchor Account. This can be verified by reviewing the “Cloud Sync Status” column on the pages below:
- Onboard > 60 GHz cnWave > Devices page for the 60 GHz cnWave devices
- Onboard > Edge Controller > Devices page for PTP8xx devices
- Onboard > Devices page for rest of the device types.
- Device onboarding
- Device deletion and On-Premises instance deletion from the Anchor Account
- Restore from a backup
- Upgrade to cnMaestro X
- Downgrade to cnMaestro Essentials
| Type | Details |

The graphic below displays the Cloud Connectivity page in the cnMaestro On-Premises UI.
The Cambium ID and Onboarding Key set in the Cloud Anchor Account need to be entered into the On-Premises UI. The graphic below displays the page in the Cloud Anchor Account UI used to change the Onboarding Key.
Manage Subscriptions
A new page, Manage Subscriptions > Subscriptions, is available in the On-Premises UI to track cnMaestro X subscription usage in an individual On-Premises instance. It provides a Usage Summary and a list of pending/active/expired subscriptions pertaining to an individual cnMaestro X instance.
Devices
The Manage Subscriptions > Devices page shows the devices in the cnMaestro X On-Premises instance. It presents a pie chart with different subscription tiers and the devices assigned to them. The table underneath lists the devices mapped to subscriptions, including the MAC Address, Serial Number, Type, Device Tier, Subscription Name, Subscription State, and Subscription Validity.
Onboarding
In the cnMaestro On-Premises Onboarding page, all existing action buttons, including Basic Details, Set Location, Update Software and Configure Devices, are now consolidated into a single Edit Device button to improve space utilization.
Additionally, the Approval/Undo Approval toggle button is replaced with an interactive icon button 
/
. the existing CBRS “Deregister Devices” action icon is replaced with 
; and a new “Cloud Sync Status” column tracks the Cloud sync status with the Anchor Account. The system automatically attempts Cloud sync when devices are approved.
Security Enhancements
Support for TLS 1.0/1.1 Removed
The underlying OS for cnMaestro 3.2.0 is upgraded to Ubuntu 20.04, and support for TLS 1.0/1.1 is removed. Devices running a lower version than that specified below cannot connect to cnMaestro.
