The <slot-number> parameter indicates that the chassis slot number for which you are changing the priority. You
can specify 1 – 4 for NetIron MLX-4, 1 – 8 for NetIron MLX-8, 1 – 16 for NetIron MLX-16, or 1 – 32 for NetIron
MLX-32.
The <priority> parameter indicates the priority of the chassis slot if the chassis loses power. You can specify a
value of 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can set one, some, or all chassis slots
to the same priority or each chassis slot to a different priority.
Disabling and Reenabling Power to the Interface Modules
If needed, you can disable power to a specified interface module and then reenable it. For example, to disable
power to the interface module in chassis slot 1, enter the following command at the Privileged EXEC level of the
CLI:
NetIron# power-off lp 1
Syntax:
power-off lp <slot-number>
The <slot-number> parameter indicates the chassis slot number for which you are disabling the power. You can
specify 1 – 4 for NetIron MLX-4, 1 – 8 for NetIron MLX-8, 1 – 16 for NetIron MLX-16, or 1 – 32 for NetIron MLX-32.
For example, to reenable power to the interface module in chassis slot 1, enter the following command at the
Privileged EXEC level of the CLI:
NetIron# power-on lp 1
Syntax:
power-on lp <slot-number>
The <slot-number> parameter indicates the chassis slot number for which you are reenabling the power. You can
specify 1 – 4 for NetIron MLX-4, 1 – 8 for NetIron MLX-8, 1 – 16 for NetIron MLX-16, or 1 – 32 for NetIron MLX-32.
Enabling and Disabling Management Module CPU Usage Calculations
You can enable the NetIron XMR Series router to perform usage averaging calculations on tasks handled by the
management module’s CPU. If you enable the calculation performance, you can display usage averages for all
tasks performed by the management module’s CPU for an interval of up to 1 hour. You can display these statistics
using the
show cpu
command. 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 the management module’s CPU
in the last 1 second.
NOTE:
The
cpu-usage
command must be configured in order to poll the MP CPU utilization.
To enable the performance of the usage averaging calculations, enter the following command at the global
CONFIG level of the CLI:
NetIron(config)# cpu-usage on
Syntax:
cpu-usage on
To disable the performance of the usage averaging calculations, enter the following command at the global
CONFIG level of the CLI:
NetIron(config)# cpu-usage off
Syntax:
cpu-usage off
NOTE:
When finished gathering statistics for debugging purposes, Foundry recommends disabling the usage
averaging calculations, which are CPU-intensive and can affect the performance of the management module.
