cnMaestro 3.0.0 (On-Premises)


This document highlights new features and significant updates in cnMaestro On-Premises.


cnMaestro 3.0.0 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 2.4.0/2.4.1/2.5.0.

Important: Update Precautions!

This update has significant database changes that require data migration. This process is done in the background, so regular network management operations are not impacted. The migration duration depends on the total number of devices, and it may take a couple of hours. We recommend limiting UI access during this period, to keep the load down. Devices will otherwise reconnect as normal.

Important: Update Precautions for CBRS Customers!

If you are using CBRS with cnMaestro acting as an HTTP Proxy, we strongly recommend configuring an external HTTP Proxy before updating to 3.0.0.

Introduction to New cnMaestro Variants

cnMaestro 3.0.0 supports two variants enabled in Cloud but not yet enforced in On-Premises:

cnMaestro Essentials

This unlicensed, free version of cnMaestro delivers the same experience as the previous cnMaestro, but without the Pro features.

Introduction to cnMaestro X

cnMaestro X Features and Benefits


If you are using cnMaestro X features, it is strongly recommended to create a Cloud Anchor account and connect On-Premises instances to it.

Introduction to Cloud Anchor Accounts

Cambium is releasing a new type of Cloud Account called an Anchor Account. The Anchor Account exists alongside current NMS Accounts (which host cnMaestro Cloud). They are attached to cnMaestro On-Premises installations and have their own Cambium ID. In the future, all On-Premises deployments must be mapped to an Anchor Account; however, in cnMaestro 3.0.0, their use is optional. The User Guide provides details on how to create an Anchor Account and associate it to one-or-more cnMaestro On-Premises deployments.

3.0 -1

Cloud Connectivity

The Anchor account collects statistics and automatically pushes announcements of new device firmware and cnMaestro software images. cnMaestro On-Premises reports the following details to the Anchor account:

Type Details
System Uptime, Processor, RAM, Disk, Virtualization Vendor
Devices Count, Type
Application Software Version, User Types and Count, Account View, Country
Features MSP, CBRS, Wi-Fi Performance, Auto-Provisioning, SNMP, etc.

In the future, Cloud connectivity will be used to manage cnMaestro X subscriptions for on-premises instances. It will also simplify the CBRS provisioning and billing by connecting multiple on-premises instances to a single cloud account.

The graphic below displays the Cloud Connectivity page in cnMaestro On-Premises.


The Cloud Anchor Account requires an Onboarding Key to establish the initial connection.


Each Cloud Anchor account supports many on-premises installations.


60 GHz cnWave Device Support

cnMaestro now integrates 60 GHz cnWave devices. The following features are available in this first production release:

Feature Details
Configuration Configuration at the Network, Site, and Device levels
Dashboard Network, Site, and Device level Dashboards

Long Term Historical Data Support in Performance Charts x

All device performance charts are enhanced for long term historical data support. Along with the existing 5-minute and 1-hour periods, a new 1-day period is added. The 1-day period will only be available in cnMaestro X accounts.

Now performance charts support long term historical data as follows:

1-Year Historical Data : cnMatrix and Wi-Fi APs (cnPilot Home, cnPilot E-Series, XV-Series).

1-Year Historical Data : IIoT devices (cnReach and Machfu).

2-Years Historical Data : Fixed Wireless Broadband (ePMP, cnVision , PMP, PTP, 60 GHz cnWave and cnRanger).


Concurrent Device Jobs x

Support for concurrent device jobs is added: Software Update, Configuration Update, and Action Jobs can be executed concurrently on a distinct set of devices.

Software Defined Radios (SDR) Support for XV3-8 Wi-Fi APs x

SDR allows splitting 8x8 5 GHz radio into two 4x4 5 GHz radios. Once enabled, the second 5 GHz radio gets split into two 5 GHz radios: Radio2 and Radio3. Both radios can be configured independently.


Scheduled Configuration Update x

Select a time to apply device configuration updates.


NTP Server Settings

User can now configure the NTP server settings from the cnMaestro GUI by navigating to Administration > Server > Settings and the Configure NTP Server section. cnMaestro uses Google and NIST Public NTP by default. To use different NTP servers, configure IPv4/IPv6 address or hostname.


Updated Home Page

The Home page is updated to provide a fresh look and overall summary of the deployment.


Consolidate Enterprise Wi-Fi APs in UI

The cnPilot E-Series and XV-Series APs are combined into one category called Enterprise Wi-Fi. The end-of-life (EoL) ePMP 1000 Hotspot is also included under Enterprise Wi-Fi AP Groups and WLANs.


The updates are also present in AP Group creation.


Miscellaneous UI Improvements

Most icons are updated, and Main Menu text is renamed as shown below:


API Updates x

Important: API Version Update to v2
The cnMaestro API version is now “v2”. The “v1” version will remain through 3.1.x and will sunset in 3.2.0, where it will no longer be supported. Most API calls are unchanged in v2, but there are revisions in few areas – especially devices and statistics. See the User Guide and online Swagger documentation for specific changes.

Cambium recommends updating to v2 as soon as possible.

Significant Fixes

The following issues have been fixed:

Id Details
AURA-470 Failure to load Success page after Quick Pay authentication.
CNSSNG-4906 Captive Portal Auto Login fails with latest Android devices.
CNSSNG-6293 Mesh Recovery WLAN Profile is not shown in On-Premises or Cloud.
CNSSNG-7328 Macros within replacement var default values not handled properly.
CNSSNG-8101 Link to device Web page using enabled protocol.
CNSSNG-8304 ePMP: “No GPS Sync” or “GPS Sync Down” alarm/event not raised in cnMaestro.
CNSSNG-10189 cnReach performance reports do not have throughput values for radios.
CNSSNG-12167 Wrong Passphrase is getting pushed to AP in WLAN Group.
CNSSNG-12455 MAC Address format should be unique in all configuration parameters.
CNSSNG-13171 Improvements to Spectrum Inquiry Response graph in Tools. This release now shows the height of each bar in the graph proportional to the EIRP (if that information is provided by the SAS vendor).
CNSSNG-13457 For cnPilot-R devices, if hostname has an embedded quotation mark, the name is truncated when pushed to devices.
CNSSNG-13598 EPSK keys are not available in exported WLAN JSON.
CNSSNG-14173 CBRS Management Tool should better display operational parameters in SAS responses. This includes a new column in the tool to show “SAS Recommended EIRP”; printing related text via hover over bubble; and the ability to request the SAS recommended EIRP by clicking on the START action button. See the CBRS Consolidated Procedures Guide for more information.
CNSSNG-14798 Option to set time zone from cnMaestro UI (On-Premises only).
CNSSNG-15160 Enable/disable SSH access from cnMaestro UI (On-Premises only).
CNSSNG-15250 Improvements to CBRS heartbeat interval and timeout handling.
CNSSNG-15251 Separate billing and technical contact information requested on CBRS Services Accounts page of cnMaestro, instead of a single set of contact information.
CNSSNG-15256 A Reimport option has been added to the CBRS Management Tool spreadsheet import function. If, for example, an operator made the same configuration mistake on every device in a sector, previous options were to edit every device one-at-a-time via pop-up GUI or delete everything and re-add with a new sheet. Now operators can use the Reimport function to change installation parameters or EIRP in any state, although a deregistration will be triggered. Changing BW or Center frequency is also supported via Reimport, but only if all devices in the sector are deregistered prior.
CNSSNG-15258 The CBRS Management Tool supports live status updates of the CBRS state of the radio. Prior to 2.4.1, the CBRS state of the device was frozen after the device flips to config_sync state. Now this field, as well as others, are updated from the device. See the cnMaestro Cloud User Guide for additional details on live status updates.

The CBRS Management Tool supports an Export function to recreate the spreadsheet based on current tool entries.

The CBRS management tool also supports ODS file format for import instead of just Excel. Note export to ODS format is not yet supported.

Editing EIRP for Config_synced devices is supported from cnMaestro, rather than just directly on the devices. See the CBRS Consolidated Procedures Guide for more info.

The CBRS Management Tool now allows editing parameters for devices in Not Synced config states other than deregistered/unregistered – i.e., one can edit parameters in an AUTH/Not synced state although a deregistration is forced by cnMaestro as part of the edit.
CNSSNG-15259 cnMaestro Reports generate CBRS related data.
CNSSNG-15313 Dashboard Throughput Graph and Capacity Graph for PTP devices are not updating other than Chrome browser.
CNSSNG-15344 Enterprise View: The Bulk device deletion happens for all devices instead of devices under APs/Switches only.
CNSSNG-15410 SMs connected to ePMP 3000 are not shown under the AP in the cnMaestro tree.
CNSSNG-15525 With 2.4.1, removing devices from CBRS Management Tool no longer deletes them from cnMaestro inventory/onboarding queue. CBRS Tool replaces the old method of Deregister per device via checkbox with Delete and Deregister action buttons near the top of the tool. With this improvement, “Deregister All” and “Delete All” options are supported.
CNSSNG-15589 Slightly higher EIRP limits allowed with 2.4.1 for certain SAS vendor/model combinations as follows:

Federated Wireless SAS:

450 SM, old limit = 45 dBm, new limit = 46 dBm,
450 AP, old limit = 45 dBm, new limit = 46 dBm
450i AP old limit = 46, new limit = 47

Google SAS:

450i old limit = 46, new limit = 47

Note : While 16.2.1 radio code supports operation with these higher limits if the Grant is obtained from the cnMaestro tool, 16.2.1 code does not support the radio requesting the higher values directly. Existing operators who deployed devices with these lower limits who want to bump up their power by 1 dB should see the CBRS Consolidated Procedures Guide version 1.3 for editing EIRP on a config_synced radio. Until newer radio software is available, an existing operator who wishes to obtain a grant with 1 dB higher power will have to deregister such device long enough to request a new grant from the tool, then sync this new grant to the device. This should be done in a maintenance window prior to a CPAS cycle.
CNSSNG-15621 The mailing address is used as a login to enter MSP users should not be case sensitive.
CNSSNG-15724 Alarm CBRS_GRANT_SUSPEND is not clearing.
CNSSNG-15726 Invalid configuration generated when VLAN’s DHCP Relay Agent is cleared.
CNSSNG-15903 Mismatch in parameters in Performance Reports (Backhaul vs Enterprise Account types).
CNSSNG-16161 Hover over message for “Registered” field incorrect in Management Tool for 2.4.1 when device builds are less than 16.2.1.
CNSSNG-16250 Exported ePSK entries are not human-friendly.
CNSSNG-16300 Configuration auto-sync queue can be corrupted by unmapped device.
CNSSNG-16402 DFS Status field with HTML tag in cnMaestro UI.
CNSSNG-16471 “Error while replacing device variables in template”, if customer AP Group is pushed from onboarding page with Auto-Provisioning rule.
CNSSNG-16574 PTP 550 dashboard throughput graph is not populating.
CNSSNG-16858 cnPilot E-Series: PPPOE details are not saved with AP Group
CNSSNG-17355 Devices are showing outside Site even though Site inventory and Site shows the device belongs.
CNSSNG-17477 Network MAP should show other Towers as well from SM/AP level.
CNSSNG-19328 Russia country code prefix is not available for SMS authentication.
CNSSNG-19335 Config sync fails when WLAN is configured with WPA2+PSK security with specific passphrase.
CNSSNG-19642 Modulation graph for intermediate modulation does not show values in performance graphs.
CPY-15253 CommScope SAS is now supported in addition to Google and Federated Wireless. Although lab testing is complete, Cambium Networks has not finished customer beta testing with CommScope. Until that validation is complete, Cambium recommends customers wait for additional announcements from Cambium indicating it is ready for general use.

Please how do u upgrade my existing cnmaestro version 2.5.0 to 3.0.0

cnMaestro 3.0.0 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 2.4.0/2.4.1/2.5.0.

I prefer to create a new vm with the ova instead of upgrade and import the data from the old version. In case of error, can return to the old vm easily.
