cnMaestro 3.0.4 (On-Premises)

Introduction

This document highlights new features and significant updates in cnMaestro 3.0.4.

Important: Package Upgrade
cnMaestro On-Premises 3.0.4 is a Package release rather than a full OVA image. It must be applied on top of an existing 3.0.0 or 3.0.2/3.0.3 On-Premises installation.

Important: Web Browser
Restart your browser (or clear the browser cache with a hard reload) if you still see the older version.

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 3.0.4.

Anchor Account Creation
Cambium recommends all cnMaestro On-Premises users create Anchor accounts for their On-Premises installations, so they can simplify CBRS management. This will become a mandatory requirement starting in cnMaestro 3.2.0.

Organizations
Only Super Administrators can configure Organizations.

Third-Party WMS Geolocation Map Server

Support for a third-party WMS Geolocation Map Server is added to replace the default cloud-based tile mapping service. This configuration is available at the Administration > Settings page.

3.0.4-op-1

60 GHz cnWave Enhancements

Instantaneous Offline Alarm

Support instantaneous “Device Offline” alarms, instead of waiting 5 minutes before sending the alarm. Enable this with caution, because it may generate false alarms due to slow or unstable connections.

3.0.4-op-11

Enhancements to Active Alarms

The following updates have been made to Acknowledged Alarms:

  1. They are no longer included in the Active Alarm count.

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).

Where to Get Help

There are several places to get help with cnMaestro:

Cambium Community : The cnMaestro Forum provides the best place to ask questions and get up-to-date information.

On-Premises Quick Start Guide : This guide walks you through the initial management process and allows you to get onboarded quickly. It is embedded into the cnMaestro image and can be accessed on the Home Page of the UI. It can also be downloaded in PDF format from the Cambium Support website.

Cambium Support : The Cambium Support team is available 24x7 to answer questions and resolve issues.

Thanks for the update Rob! We have a support ticket with Cambium referencing CNSSNG-20911. I didn’t see it in the fixed bugs nor open bugs list. Would it be possible to share the status of this ticket?

Hi @rnelson - this was fixed and made it into the 3.0.4 release too (sorry it didnt make the major fixes list!)

The whole point of using the on-prem is to not share data outside the network. If we are not using CBRS, then an anchor account should not be required. Please make this optional.

We share the same opinion

Its less of an opinion and more of a requirement.

In todays internet any surface area is an attack vector, including remotely hosted services. It could be said that a property configured firewall will reduce the attact vectors but that wont stop a man in the middle attack nor will it stop a social attack. Its hard enough keeping your own co-workers from just blindly clicking things, but now we have a third-party that we really dont want having access to our network to worry about.

This seems like Cambium wants us to pay for device licenses (think Motorola’s Wireless Manager) on devices we own (Meraki anyone?) and by binding our service to an account they control they can turn off our service or that same access can be used to gather information about our network without our expressed consent regardless of how that data is intended to be used.

The total lack of consideration towards our security rights and our policies has significantly reduced our use of this product and since it has already been announced that all revisions going forward will require an anchor account, we are looking to abandon the product.

So I was considering giving CNMaestro another go. I’m setting here with a server I just got all set up and I come here looking for the software / instructions etc… to get it going and…

Anchor Account Creation
Cambium recommends all cnMaestro On-Premises users create Anchor accounts for their On-Premises installations, so they can simplify CBRS management. This will become a mandatory requirement starting in cnMaestro 3.2.0.

Aside from the already pointed out just one more hole I have to punch in my defenses and maintain and take into consideration and worry about until the end of time for no reason other than Cambium wants information they can use/sell/whatever. As someone that only used CNMaestro briefly and when it first came out… will my on premisis CNMaestro go down or stop working every time there is a hiccup that causes it to lose connection to the Cambium Mothership ?

Seriously… if there was a Super Hero called CambiumMan he would have all the powers of Superman but Cambium would make his Super Suit out of Kryptonite… and he would randomly punch you in the face and ask you for cigarette money.

Edit: Also, no links in the above release-notes post to any of the alluded to files/documents/support. I’m not finding anything called a " Quick Start" anything in files download area only the regular On Prem User Guide.

Edit Edit :

It can also be downloaded in PDF format from the Cambium Support website.

Well yes and no… or at least I think you mean you can download the On Premises User Guide and it has a Quick Start section in it. There is , or at least not that I can find, no stand alone Quick Start Guide that can be downloaded.

We don’t use on premise, but I believe the hole is for your licensing management. So as long as your not down for a significate time and or you don’t have any licensing management then I believe you should be good to go.
