Setting the Threshold Limit for the PoE Power Budget To set the global threshold limit of the total power available for PoE on the port extender, use the power budget global-threshold pe pe-id stack-unit unit-number threshold-value command in Configuration mode. This command has the following parameters. • pe pe-id - Enter the keyword PE and specify the port extender ID. The range is from 0 to 255. • stack unit unit-number - Enter the keywords stack unit and specify the stack unit number of the port extender. The range is from 0 to 7. • threshold-value - Enter a value between 20 and 99. The default value is 90 (90 percent). • Set the global threshold limit of the total power available for PoE on the port extender. You must be in Configuration mode. power budget global-threshold pe pe-id stack-unit unit-number threshold-value Example of Setting the Global Threshold Limit for the PoE Power Budget The following example sets the global threshold limit for the PoE power budget to 99 percent on port extender 0 on stack unit 0.
