Introduction
This document highlights new features and significant updates in cnMaestro On-Premises.
|
Important |
|
cnMaestro 2.3.0 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 with 2.1.0/2.2.0 OVA. |
|
Important: Web Browser |
|
You may need to restart your browser (or clear the browser cache with a hard reload) after the 2.3.0 update. |
Webhooks (On-Premises) 
Webhooks provides real-time streaming for Alarms using a push notification model. It uses HTTPS POST to asynchronously forward alarm data to external Web Services, such as Slack, Twilio, Zapier, Datadog, and PagerDuty. Webhooks configuration is available at Application > Settings > Webhooks.
Audit Logs
cnMaestro now supports Audit Logs, which record administrator activities. Audit Logs entries can be found at Application > Audit Logs.
System Events (On-Premises)
cnMaestro System events are now accessible. They include infrastructure events (such as for high availability) and system resources (such as CPU, disk, and memory).
Syslog Server (On-Premises)
Ability to stream events and audit logs to an external system log server. Syslog server configuration is available at Application > Settings.
Automatic Software Update
Support automatic software update during onboarding and for managed devices. This feature allows one to configure a software version and automatically update devices during onboarding for new devices, or through scheduled updates for currently managed devices. Software Update Jobs are split to track the progress of manual and automatically created jobs. The Automatic Software Update option is available at Application > Server > Software Images.
Software Update > Auto Jobs
Troubleshooting Tools for On-Premises (On-Premises)
Support basic troubleshooting tools such as ping, DNS Lookup and Traceroute in the On-Premises server. This feature is available at Application > Server > Diagnostics > Network Tools.
Increased cnMaestro Users Limit (On-Premises)
The limit for cnMaestro users is increased from 10 to 100. Please note10 remains the maximum for Essentials, and 100 uses will be a future Pro feature.
Web Access for Device UI Launch
Launch the device Web UI using the configured access protocol (HTTP/HTTPS) rather than defaulting to HTTPS. For this feature to work correctly, cnPilot Enterprise devices must be mapped to AP Groups.
Special Characters in Object Names
Support special characters in Networks, Sites, Towers, AP Groups, WLANs, and Managed Accounts names. Previously, special characters were limited to hyphen (–) and underscore (_).
Association ACL in Managed Accounts (MSP)
Association ACLs are now available in Managed Accounts (previously, they were limited to the Base Infrastructure).
Improvements to Configuration Sync
Configuration Sync is enhanced for cnPilot devices to automatically execute blocked jobs when they become unblocked. Earlier, manual intervention was needed.
Rename AP Groups and WLANs
Ability to rename AP Groups and WLANs.
Roaming History for Mesh Peers
Roaming history for Mesh Peers is available and similar to regular wireless clients.
Exclusive WiFi4EU Template for Guest Access Portal
WiFi4EU template added to support easy customization of splash page for WiFi4EU-based Guest Access Portals.
Hostname Change for cnPilot Home Devices
Push hostname changes to cnPilot Home devices. This requires device software version 4.6-R5 or higher.
Improvements to cnMatrix Support
The improvements include the ability to modify hostname and a new Tools page for advanced debugging. These features are supported on cnMatrix devices running software version 2.0.5 or higher.
Report for Capped PMP SMs
Capped SM data is available in the Inventory view and SM Device Details page.

General UI Improvements
Improved responsive design for mobile devices, especially configuration. Also, column resizing and column reordering capabilities in grids.
Swagger Support for NBI API Documentation (On-Premises)
Swagger documentation can be launched from Services > API Clients for individual API Clients. It also provides a live playground to test APIs.
