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 8.0

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.

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.

Key	Known Issues
S1NPM-113199	Wifi-Solution-6a_Cisco-WLC-AP-Inventory-Report: The device drop-down may not populate due to incorrect variable binding to the WiFi device group; this is not a synchronization or connectivity issue. Workaround: Edit Select a Cisco Wifi WLC Device, manually select the WiFi device group, and then choose the device to display data.
S1NPM-116559	When the device is onboarded to SevOne NMS, certain metadata values in the Performance Metrics - SNMP Availabiltiy page are not populated as expected.
S1NPM-116837	After adding Wireless LAN Controllers (WLCs) on SevOne NMS 8.0.0, 400 Client Error is observed on the endpoint /api/v3/indicators/last-seen in the /var/log/wifi-wlc/disable_objects log .
S1NPM-116928	WiFi: In SevOne NMS versions 8.0.0 through 8.0.6, after integrating Wireless LAN Controllers (WLCs) with a large number of Access Points, WiFi collector polling on the NMS peer may become interrupted or stop unexpectedly, impacting data collection. Workaround: From the SevOne NMS command line interface, restart the WiFi collector container. `podman restart nms-collections-wifi-collector` Note: This issue is resolved in SevOne NMS version 8.0.7 and later.
S1NPM-117039	Platform: In a fresh installation of SevOne NMS version 7.2.0, the Device Type Membership tab does not display device-related details for both the SC CISCO ACI HYPERVISOR and SC CISCO ACI VM device types. Furthermore, after upgrading SevOne NMS from version 7.2.0 to 8.0.0, the Device Type Membership tab does not display device-related details for the SC CISCO ACI VM device type.
S1NPM-117227	After the installation of SevOne NMS 8.0.0, the WiFi Station Monitor policy is not displayed on the Policy Browser page.
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.
S1NPM-119377	When WiFi collector becomes unavailable and later resumes operation, the SevOne NMS graph connects the latest data point to the last recorded value. As a result, the graph does not display the gap in data collection during the collector outage.
S1NPM-119869	WiFi Disable Object script may fail when the indicators/last-seen API endpoint returns objects with id = 0 due to unresolved indicators. The script does not validate object IDs before processing and proceeds with API requests using the invalid id = 0, resulting in execution errors and failure logs. This issue requires a validation check to skip objects with id = 0.
