cnMaestro 3.1.1 (Cloud)

Introduction

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

Important: Web Browser
Restart your browser (or clear the browser cache with a hard reload) if you are having UI problems with the 3.1.1 version.

Improved Application Visibility at the Network Edge X3

cnMaestro X provides Wi-Fi application visibility for over 2,400 applications. This release adds application history support for System and Sites (in addition to the existing Client Devices). To review application usage history, navigate to Monitor and Manage and select a System or Site node. The Application History tab displays top applications, top clients, total bytes consumed, and percentage of traffic generated by the application.

Expanded Wi-Fi 6/6E Portfolio

Full management for XE3-4, XE5-8, and XV2-2T1 access points is now available in cnMaestro. The XE5-8 is an industry-exclusive 5-radio high density AP supporting 15.6 Gbps total Wi-Fi bandwidth. The two XE-series access points support Wi-Fi 6E with software-defined radios (SDRs) selectable between 5 GHz and 6 GHz operation. The XV2-2T1 is an ultra-long-range outdoor Wi-Fi 6 AP with integrated 120-degree sectored antennas capable of client connections over 1 km in distance. To configure the SDRs on the XE-series APs, navigate to the AP Group > Radio page. In the Software Defined Radios section, you can configure software definable radios for the XV3-8, XE3-4, and XE5-8 access points.

Wi-Fi 6E Migration Assistant

As the number of Wi-Fi 6E clients increases, the new Wi-Fi 6E Migration Assistant can help manage this transition using a set of helpful widgets:

  1. The Connected 6E Client Capability widget tracks clients and recommends when it may be appropriate to switch SDR radios from 5 GHz to 6 GHz.

  2. The Client Capability History widget tracks client capabilities over time to visualize 6E client trends. (This assists with the decision to change 5 GHz radios to 6 GHz radios.)

To view these widgets, navigate to Monitor and Manage and select a Site. These two widgets indicate the device capabilities of the connected clients. When the 6E Clients on the non-6 GHz Radios indicator starts to climb, it is time to consider changing SDR radios to 6 GHz. Click the Learn more link for more information about the details of your client device capabilities.

Rogue Device Information and History X3

cnMaestro X collects information about rogue devices detected around your network. You can view information such as SSID, Channel, RSSI, and nearest AP. To view Rogue AP activity, navigate to Manage and Monitor > Site > WIDS . The WIDS page displays Rogue AP history and detailed information about detected devices. This feature was available in cnMaestro X 3.1.0 On-Premises, and it is now available in cnMaestro X 3.1.1 Cloud.

View Client Activity History Up to 7 Days X3

The Clients page displays tabular device information, network details, Wi-Fi capabilities, band, SSID, RSSI, SNR and more. You can now access client history over 24 hours or 7 days. To view the client list, navigate to Monitor and Manage > System > Clients. On the dropdown next to Clients, select the period to review: Current, 24 Hours, or 7 Days. This will display the state of all clients that accessed the system within the interval. This feature was available in cnMaestro X 3.1.0 On-Premises, and it is now available in cnMaestro X 3.1.1 Cloud.

Increased ePSK Scale X3

ePSK provides individualized, secure credentials that simplify onboarding and enable efficient roaming on a single SSID across an entire Wi-Fi network. With this release, Cambium has doubled ePSK scalability from 1,000 to 2,000 per AP and increased the total ePSK entries per account to 50,000.

To create ePSKs, navigate to Configuration Settings > AP Groups and WLANs > WLANs . Open an existing WLAN and go to the ePSK page. Click the Add New button. You can create ePSKs individually or in bulk, or you can import your own custom list of ePSK users. You also have the option of using a RADIUS server for authentication to scale even further.

Bulk Configuration of Access Points X3

cnMaestro X supports bulk AP configuration by importing a .csv file with Location, Management VLAN, Radios, and WLANs settings. To configure APs in bulk, navigate to Monitor and Manage > Site > APs > AP Configuration . Select the device type and the devices, then click the Configure button. Choose the AP Group from the dropdown window and expand Device Overrides. Finally, select the APs and click the Import button to import your custom settings.

Multi-Floor Sites X3

cnMaestro has updated Wi-Fi Site Floor Plans to support multiple floors for cnMaestro X customers.

3.1.1-7

Customers can add additional floor metadata in preparation for Wi-Fi Heat Map support later in 2022.

3.1.1-8

Converged Management for Xirrus Wi-Fi X3

cnMaestro X manages Xirrus Wi-Fi APs together with Cambium’s wireless fabric in a single console. This provides investment protection for existing Xirrus customers migrating to Cambium’s converged Wi-Fi 6/6E solutions. Xirrus AP models supported in cnMaestro X include:

  • All XD-series
  • All XH-series
  • All XA-series
  • XR-series modular 11ac Wave 1/Wave 2
  • XR-620 and XR-630

Important: Software Requirements
Operation of Xirrus APs in cnMaestro X 3.1.1 requires AOS version 8.7 on the APs. If migrating Xirrus APs from XMS-Enterprise to cnMaestro X, XMS-Enterprise version 8.4 provides automated functionality to support configuration export. Both the AOS 8.7 and XMS-Enterprise 8.4 releases are planned for June 2022.

Improved 60 GHz cnWave Visibility X3

cnMaestro X improves monitoring and troubleshooting of links and activity on cnWave 60 GHz networks. You can easily visualize a network’s RF channel plan (color-coded) and Golay code assignments, plus real-time uplink and downlink RF link performance KPIs including RSSI, MCS, SNR, and more.

To view the cnWave 60 GHz network, Navigate to the Map side tab and select the E2E Network to review. In the configuration panel on the right side of the page, access the Device Overlay view, where you can enable visualization of the status of devices, the channel and polarity of the radios, and the sector of the radio. You can also access a Link Overlay view, which presents the Status, Golay, SNR, MCS, RSSI, and Link Fade margin on the different links in your 60 GHz network.

60 GHz cnWave Improvements

Below are the improvements in 60 GHz cnWave

  • Network Level Auto-Refresh : The Auto Refresh option refreshes statistics automatically for Links and Nodes for 5 minutes. By default, the Refresh Interval is 10 seconds. This option is available on the E2E Network > Links > Statistics and E2E Network > Statistics pages.

3.1.1-11

  • Onboard E2E to External E2E Migration : You can migrate an Onboard E2E Network to External E2E network by following simple steps.

3.1.1-12

  • Link Events Redesign and Improvements : Link Events provide the details of hourly link availability timeline, percentage availability, and distance.

3.1.1-13

  • Additional Performance Statistics : Below are the new graphs added:

    • Sector and Ethernet Throughput (Rx/Tx)

3.1.1-14

  • Scan Beams (Rx/Tx)

  • Management Link Up and Delta (Link Up/Link Available)

3.1.1-15

  • Link Fade Margin (for devices running 1.2.2)

BER Information for PMP SMs

3.1.1-16

3.1.1-17

Additional Statistics for PMP 450m

The below statistics are added for PMP 450m:

  • SU-MIMO Frame Utilization
  • MU-MIMO Frame Utilization
  • Multiplex Gain

ePMP Installation Summary X3

The PMP Installation Summary has been extended to ePMP. In combination with cnArcher, cnMaestro X simplifies the ePMP SM installation process by automatically pushing information from cnArcher to cnMaestro X when the ePMP SM is deployed.

Map Enhancements X3

The Terrain view support is added to the map options.

3.1.1-20

Map View for cnMatrix, Sites and Wi-Fi APs
