Note:

T & S - Tested & Supported

Important: For multiple containers to run properly, minimum memory required is (2 + n * 1) or more GB where, n = number of containers.

When SevOne NMS is upgraded, Wi-Fi Plugin is upgraded automatically.

Note: Upgrade from SevOne NMS 7.0.x to SevOne NMS 7.2

The Wi-Fi solution has been refactored to use native integration. If you are upgrading from SevOne NMS version 7.0 or earlier, the Wi-Fi plugin is automatically configured and upgraded to the corresponding version.

Important changes introduced by this change

Every Controller that was previously enabled for the Wi-Fi solution, will have the Wi-Fi Plugin automatically enabled and configured as part of the upgrade process.
All the settings that were historically controlled via aruba.env and cisco.env files are now automatically migrated over to:
- SevOne NMS Wi-Fi Plugin user interface.
- wifi_global_settings.json file which contains the environment variables.
- advanced_config.env file which contains the advanced environment variables.
Other configuration files remain unchanged and are configurable on every peer. Existing configurations are also migrated to their new locations. Please refer to Additional Configuration Files for details on the following files.
- oui.csv.sample - contains mapping information between the first six characters of MAC addresses for station objects and their corresponding manufacturers.
- disable_config.json - input file for the script that disables objects.
- phy_types.json - contains mapping information for the physical radio types of stations.

New Features / Enhancements

Edit online

Wi-Fi Access Points (APs) and Wireless LAN Controllers (WLCs) has new features which has automated monitoring and alerting system capable of tracking the association and disassociation events of APs with their respective WLCs.

The following are the new features.

Automated Monitoring - Regularly monitors and checks the status of each AP and WLC and is able to identify if an AP is associated or disassociated from its WLC. It is able to detect if an AP or WLC is down, or if there are issues with IP allocation, CAPWAP tunnels, digital certificates, etc.
Real-time Updates - Updates SevOne NMS in real-time with the status of each AP and WLC. This ensures that the NMS always has the most current information.
Alerting Mechanism - Has an alerting mechanism that notifies the networkadministrator immediately when an AP disassociates from its WLC or when an AP or WLC goes down.
Historical Data Logging - Maintains a log of all association and disassociation events, along with the reasons for disassociation. This historical data can be used for troubleshooting and performance analysis.

By implementing these features, SevOne NMS can proactively manage Wi-Fi APs and WLCs, ensuring optimal network performance and quick resolution of any issues.

Note:

SevOne NMS version 7.2.x is now enhanced with advanced alerts for Access Point Availability. A new indicator WLC Availability is integrated into the Access Point (AP) device and indicates the availability of the corresponding Wireless Controller (WLC).

When there is no data received from an Access Point from it’s last known WLC, the Availability indicator is set to Null, and the associated availability meta-data is set to unknown. To take the WLC status into account, the alert must include the new Availability WLC indicator as shown below. The bad polls Operator is used when an Indicator has Null values. Please ensure any existing alerting policies are adjusted accordingly.


Condition	Indicator	Comparison Operation
A	Average Availability	bad polls
B	Average Availability WLC	equal to 100 Percent

Resolved Issues

Edit online

Important: It is strongly recommended to run the external security scans such as Nessus, Snyk, or similar on the latest available patch for this release to verify whether the vulnerability has been addressed. If upgrading the production environment is not currently possible, these scans can still be performed in a lab or test environment.

S1NPM-112642: Addressed CVE-2024-24786.

Known Issues

Key	Known Issues
S1NPM-100819	Wi-Fi Widgets: The following reports do not support report linking in the column Wifi Access Point.WLC Name. Wifi Solution - 2a. AP Group Report Wifi Solution - 2b. AP Report
S1NPM-100822	Wi-Fi Widgets: Import of out-of-the-box (OOTB) reports from Wi-Fi 6.6 builds to SevOne Data Insight < 6.6 is not supported.
S1NPM-100830	Wi-Fi Widgets: Upon initial loading, the following reports will display an error message No Service!. However, you can select a device from the Report variable to resolve this issue. Once you select a device, the report will function as intended. Wifi Solution - 6d. Cisco WLC Rogue AP Report Wifi Solution - 6e. Cisco WLC CDP Neighbor Report
S1NPM-112937	Wi-Fi Widgets: For OOTB reports, the following Object Groups are not created after importing the .spk files. Wifi - All WLC Statistics Wifi - All WLC Agg essid Wifi - All AP Statistics
S1NPM-119222	Files in the `config/collectors/wifi/backup-config` directory are retained to maintain a history of configuration backups. Implementing a cleanup or rotation mechanism would improve file management and help ensure efficient use of disk space on the node. Workaround: Until an automated cleanup solution is implemented, files can be manually deleted on a periodic basis to control disk space utilization.
