Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.

Configuration restrictions and guidelines

When you configure process placement, follow these restrictions and guidelines:
Configuring process placement on a device with only one CPU does not change the location of
•
processes.
Configuring process placement on a device with multiple CPUs places specific active processes to
•
specific CPUs. In case of multiple CPUs, the system performs 1:N process redundancy, where N
must be less than the number of CPUs. The number of standby processes and their CPU locations
vary by function module. The system by default automatically determines the location for each
active process, and there is no need to optimize process placement. If optimization is needed, work
with HP engineers to avoid service interruption.
Process placement applies only to MPUs. The configuration does not take effect on an interface
•
card even if it has a CPU and is configured as location affinity for a process.
The main and auxiliary CPUs on an MPU, if any, are equal for process placement. You can place
•
an active process either on a main CPU or an auxiliary CPU. You can view the final result by using
the placement reoptimize command.
