Enabling and disabling management module CPU usage calculations 7Brocade# power-on lp 1To re-enable power on all interface modules, enter the following command.Brocade# power-on lp allIn this output example, there is one interface module in slot 3 and slot 3 is powered on.Brocade# power-on lp allSlot 3 is powering on.rw_power_on_lp: write 00070004 to RW_MBRIDGE_CARD_POWER_OFF_REGSyntax: power-on lp [| all]• The parameter indicates the slot number for which you are re-enabling thepower. You can specify 1 – 4 for 4-slot routers, 1 – 8 for 8-slot routers, 1 – 16 for 16-slotrouters, or 1 – 32 for 32-slot routers.• The all parameter allows you to power on all interface modules.Enabling and disabling management module CPU usage calculationsYou can enable the router to perform usage averaging calculations on tasks handled by CPU on themanagement module. You can then display usage averages for all tasks performed by the CPU onthe management module for an interval of up to one hour. You can display these statistics usingthe show cpu command.NOTETypically, these statistics are used for debugging purposes.By default, the performance of the calculations is disabled. When disabled, you can use the showcpu command without optional parameters to display usage averages for all tasks performed byCPU on the management module.NOTEThe cpu-usage command must be configured in order to poll the MP CPU utilization.To enable the usage averaging calculations, enter the following command at the global CONFIGlevel of the CLI.Brocade(config)# cpu-usage onSyntax: cpu-usage onTo disable the usage averaging calculations, enter the following command at the global CONFIGlevel of the CLI.Brocade(config)# cpu-usage offSyntax: cpu-usage offNOTEWhen you are finished gathering statistics for debugging purposes, it is recommended that youdisable the usage averaging calculations, which are CPU-intensive and can affect the performanceof the management module.Brocade MLX Series and Brocade NetIron XMR Hardware Installation Guide 34553-1002373-02
