Enabling and disabling management module CPU usage calculations 7

Brocade# power-on lp 1

To re-enable power on all interface modules, enter the following command.

Brocade# power-on lp all

In this output example, there is one interface module in slot 3 and slot 3 is powered on.

Brocade# power-on lp all Slot 3 is powering on.

rw_power_on_lp: write 00070004 to RW_MBRIDGE_CARD_POWER_OFF_REG

Syntax: power-on lp [<slot-number>all]

•The <slot-number> parameter indicates the slot number for which you are re-enabling the power. You can specify 1 – 4 for 4-slot routers, 1 – 8 for 8-slot routers, 1 – 16 for 16-slot routers, 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 calculations

You can enable the router to perform usage averaging calculations on tasks handled by CPU on the management module. You can then display usage averages for all tasks performed by the CPU on the management module for an interval of up to one hour. You can display these statistics using the show cpu command.

NOTE

Typically, these statistics are used for debugging purposes.

By default, the performance of the calculations is disabled. When disabled, you can use the show cpu command without optional parameters to display usage averages for all tasks performed by CPU on the management module.

NOTE

The cpu-usagecommand must be configured in order to poll the MP CPU utilization.

To enable the usage averaging calculations, enter the following command at the global CONFIG level of the CLI.

Brocade(config)# cpu-usage on

Syntax: cpu-usage on

To disable the usage averaging calculations, enter the following command at the global CONFIG level of the CLI.

Brocade(config)# cpu-usage off

Syntax: cpu-usage off

NOTE

When you are finished gathering statistics for debugging purposes, it is recommended that you disable the usage averaging calculations, which are CPU-intensive and can affect the performance of the management module.
