The Extreme Networks wireless LAN controller management software is a recommended utility to plan the
deployment of the controller and view its configuration once operational. Extreme Networks WMS can help optimize
the positioning and configuration of a controller and assist in the troubleshooting of performance issues as they are
encountered in the field.
Displaying the Main Diagnostic Interface
The main diagnostic screen contains tabs assessing the performance of the following diagnostics:
● Controller Environment
● CPU Performance
● Controller Memory Allocation
● Controller Disk Allocation
● Controller Memory Processes
● Other Controller Resources
When the controller’s configuration is successfully updated (using the Web UI), the affected screen is closed without
informing the user their change was successful. However, if an error were to occur, the error displays within the
affected screen’s Status field and the screen remains displayed. In the case of file transfer operations, the transfer
screen remains open during the transfer operation and remains open upon completion (with status displayed within
the Status field).
Controller Environment
Use the Environment tab to view and modify the controller diagnostic interval, temperature sensors and
fan speeds.
