cnMaestro 4.1.0 (On-Premises) Release Notes

Introduction

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

Important: OVA Upgrade
cnMaestro 4.1.0 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 3.2.0/4.0.1.

Important: System Backup
It is strongly recommended to take a System Backup prior to upgrading to 4.1.0. This can be done in the UI at Administration > Server > Operations. This is required in case you ever want to downgrade to the previous version.

Site Level Assists X

Assists are now available at the Site level. This feature scans supported device configuration across a Site and generates an Assists Score, displayed as a percentage of successful evaluations. This provides valuable insights, recommendations, and troubleshooting assistance. With Assists, network administrators gain enhanced visibility, proactive recommendations, and improved efficiency in managing their networks.

4.1.0-3

ePSK Lifecycle Management X

ePSK (Enhanced Pre-Shared Key) Life Cycle Management offers a range of benefits for managed Wi-Fi services. ePSK ensures a secure and hassle-free experience for residents, eliminating the need to manage numerous PSKs (Pre-Shared Keys) manually. This new feature includes automatic expiry of ePSKs; seamless renewal of keys; and inline modification of ePSKs – all aimed at simplifying the management process. For added convenience, ePSKs deactivate automatically on specified future dates, such as the resident’s move-out date. Network managers can easily adjust these termination dates in the event of changes, ensuring a smooth and efficient Wi-Fi service for all residents.

4.1.0-4

Personal Wi-Fi X

Personal Wi-Fi addresses requirements in Multi-Dwelling Units (MDUs) and similar hospitality-related networks. Each user on the network effectively operates on their own secure Wi-Fi network as if they had a personal Wi-Fi router. Users can seamlessly roam across the property with ubiquitous connectivity while maintaining personal security via a unique ePSK and VLAN. This functionality is provided with a unique SSID for the user in their personal space (apartment, dormitory room, etc.) but with a common property SSID in public areas. The same personal ePSK credentials are used across both SSIDs, and roaming is seamless for the user. For property managers, this personalized approach ensures tenant privacy and security while minimizing administration overhead.

4.1.0-5

Graphical Reports X

Graphical Reports represent data visually to improve consumption and summarization. They can be generated and customized with logo, brand image, and theme by creating/editing Graphical Report Templates with selected widgets. These reports can be generated by clicking Add New Graphical Report at System and Site levels under Reports > Scheduled. Each report can be downloaded in PDF format and contains graphs, charts, and data tables.

To create Graphical Report Template, navigate to Configuration > Graphical Report Template and click on Add New button.

4.1.0-6

Add New Graphical Report Template window pops up with Name, Title, Scope, logo, brand image, and themes.

4.1.0-7
