Significant Fixes

The following issues have been fixed:

Id

Details

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-14173

CBRS Management Tool better displays info on 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-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-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)

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 avoid CommScope and wait for additional announcements from Cambium indicating it is ready for general use.

Known Issues

The following issues exist:

Id

Issue

Details

AURA-470

Failure to load success page after quick pay authentication

CNREACH-139

Radio Software Update is not happening for EP based devices.

CNSSNG-4083

DHCP errors after cnMaestro reboot

When cnMaestro On-Premises is rebooted, after Data Import, sometimes DHCP and Disk Errors are encountered.

Workaround: Explicitly run the dhclient command from the Command Line (accessed through the CLI) after reboot to assign the IP address.

CNSSNG-4906

Captive Portal Auto Login fails with latest Android devices

Workaround: Whitelist the URL for Google (*.google.com).

CNSSNG-5365

RADIUS Proxy drops packets after retry exhausted

After RADIUS Proxy Retries are exhausted in cnMaestro On-Premises, all subsequent RADIUS packets are dropped.

Workaround: Reboot cnMaestro.

CNSSNG-6293

Mesh Recovery WLAN Profile is not shown in On-Premises or Cloud.

CNSSNG-8304

ePMP: “No GPS Sync” or
“GPS Sync Down” alarm/event not raised in cnMaestro

ePMP devices are not sending the GPS Sync status events to cnMaestro when GPS Sync is down or there is NO GPS Sync.

Also for PMP GPS SYNC events, details shows sync source instead of indicating whether the GPS SYNC source is up or Down.

CNSSNG-9631

High Availability: Network cable unplug: Device count is taken from Primary and jobs/users list is taken from Secondary.

CNSSNG-9632

High Availability: Network cable unplug: Devices onboarded during network disconnect need to be reapproved by user.

CNSSNG-10145

Certificate exports are not part of Data Backup and Restore

Certificates must be exported manually.

CNSSNG-10187

While Migration is happening, moving or deleting a device from the Managed Account will mark all the events and alarms as undefined once migration is completed

CNSSNG-10189

cnReach performance reports do not have throughput values for radios

CNSSNG-11299

AP Regulatory Channel list support check needed for checking valid channels.

CNSSNG-11389

Microsoft Edge Browser does not support in system OVA file upgrade.

Workaround: Use the Google Chrome browser

CNSSNG-11987

CNSSNG-12888

Connected Clients count in the WLAN page is not properly shown when SSID is overridden for the particular WLAN at device level.

CNSSNG-13144

CBRS Management tool status field is not updated in heartbeat state.

Workaround: Prior to syncing the configuration to the radios, any state change from the SAS does not automatically get updated on cnMaestro. A refresh on the Management tool page is necessary.

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 not available in exported WLAN JSON.

CNSSNG-14030

CBRS: Race condition - SM "stuck" in cnMaestro during reparenting if import and start occurs as SMs arrive in onboarding queue

Workaround: To avoid this issue, follow the suggested SM reparenting procedures listed in the latest version of Cambium CBRS standalone procedures document.

CNSSNG-14518

Device Type drop down need to be provided at Site and AP Group level for reports generation.

CNSSNG-15313

Hover over message for "Registered" field incorrect in Management Tool for 2.4.1 when device builds are less than 16.2.1

Workaround: Devices should have 16.2.1 or higher builds for live status to be shown properly with cnMaestro 2.4.1 release

CPY-16763

cnMaestro still shows device deregistered and not synced.

FLCN-7839

[Tiger/Jaguar]

[Jaguar/Tiger] AP keeps renewing IP address continuously, when IP address is added in cnMaestro GA whitelist entry, due to which GA redirection also fails in this scenario, as AP uplink ethernet connectivity keeps flapping.

FLCN-7847

[Tiger/Jaguar]

With cnMaestro GA, client GA session is not maintained after AP reboots, as AP is not sending client cache query to cnMaestro when client connects back. cnMaestro based roaming also will not work due to this issue.

FLCN-7857

[Tiger/Jaguar]

cnMaestro GA redirection fails with WLAN mapped to NAT'ed interface.
