Parameters
chassis chassis-number slot slot-number: Specifies an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the device, which is fixed at 0. (In IRF mode.)
&<1-5>: Indicates that you can specify a maximum of five CPUs.
attract strength: Sets a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for the process to run in the specified CPU.
default: Sets the affinity to the default, a positive affinity of 200.
none: Sets the affinity to 0, which means the active process has no preference for any location and the system determines its location.
repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for the process to run in the specified CPU.
Usage guidelines
This command sets the preference for a process to run on a specific CPU.
Examples
# (In IRF mode.) Set a positive affinity of 500 to the MPU in slot 0 on IRF member device 1 for BGP.
<Sysname> system-view
[Sysname] placement program bgp
[Sysname-program-bgp] affinity location-set chassis 1 slot 0 attract 500
affinity location-type
Use affinity location-type to set the affinity of a process to a location type.
Use undo affinity location-type to remove the affinity setting for the specified location type for a process.
Syntax
affinity location-type { current | paired | primary } { attract strength | default | none | repulse strength }
undo affinity location-type { current | paired | primary }
Default
No location type affinity is configured for any process.

Parameters
current: Specifies the affinity to the current location. You can use the display placement program command to view the current location of a process.
paired: Specifies the affinity to the location of a standby process.
primary: Specifies the affinity to the master device. (In IRF mode.)
attract strength: Sets a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference of the process to run on the specified location type.
default: Sets the affinity to the default, a positive affinity of 200.
none: Sets the affinity to 0.
repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for the process to run on the specified location type.
Examples
# Set a positive affinity of 500 to the current location for BGP.
<Sysname> system-view
[Sysname] placement program bgp
[Sysname-program-bgp] affinity location-type current attract 500

Parameters
program-name: Specifies the name of a process, a case-insensitive string of 1 to 15 characters. You can use the display placement program all command to view information about placeable processes.
attract strength: Sets a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for the current process to run on the same location as the specified process.
default: Sets the affinity to the default, a positive affinity of 200.
none: Sets the affinity to 0, which means the active process has no preference for any other process and the system determines its location.
repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for the current process to run on the same location as the specified process.
Usage guidelines
Use this command to have processes run on the same location or different locations.
Examples
# Set a negative affinity of 200 for OSPF to run on the same location as BGP.
<Sysname> system-view
[Sysname] placement program ospf
[Sysname-program-ospf] affinity program bgp repulse 200

Parameters
attract strength: Specifies a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for all the instances of the current process to run on the same location.
default: Sets the affinity to the default, a positive affinity of 200.
none: Sets the affinity to 0, which means the instances of the process have no preference to run on the same location and the system determines their locations.
repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for all the instances of the current process to run on the same location.
Usage guidelines
This command sets the preference for a process to run all its instances on the same location or different locations. If the process has only one instance, the command does not take effect.
The self affinity in the placement process view of a process and any of its instances overwrite each other, and whichever is configured the last takes effect on all the instances of the process.
To view the instances of a process, use the display placement program all command.
Examples
# Set a negative self affinity of 200 for BGP.
<Sysname> system-view
[Sysname] placement program bgp
[Sysname-program-bgp] affinity self repulse 200

Parameters
program-name: Specifies a process name, a case-insensitive string of 1 to 15 characters.
instance instance-name: Specifies the name of an instance of the specified process. The instance name is a case-insensitive string of 1 to 31 characters. If a process has only one instance, the system displays a prompt when you specify this option.
default: Configures the default placement policy for all processes.
Usage guidelines
You configure a process placement policy to optimize the distribution of processes in your system for optimal distribution of CPU and memory resources.
An active process running only on the master device does not support placement optimization. If you configure a process placement policy for the process, the system displays a configuration failure prompt. When such an active process fails, the system automatically restarts the process. The standby processes are used for active/standby switchover and ISSU. (In IRF mode.)
Some active processes can run on either the master or subordinate device. When such an active process fails, the system uses a placement policy to select a new active process among standby processes. (In IRF mode.)
A process placement policy contains the affinity location-type, affinity location-set, affinity program, and affinity self commands. The commands describe the preferences of the process for a specific location.
You can configure all the affinity commands in the placement policy for a process. Based on the placement policy and hardware resources, the system automatically determines the location for running the process. Before you apply the policy, you can use the display placement reoptimize command to view the predicted location for the process.
Examples
# Enter the placement process view of BGP.
<Sysname> system-view
[Sysname] placement program bgp
[Sysname-program-bgp]
# Enter the placement process view of BGP instance 100.
<Sysname> system-view
[Sysname] placement program bgp instance 100
[Sysname-program-bgp-100]
# Enter default placement process view.

placement reoptimize
Use placement reoptimize to apply configured process placement policies for optimizing process placement.

Usage guidelines
After you execute this command, the system bases its placement decisions on the new process placement policies, hardware resources, and locations and states of active processes. If the new location for an active process is different from its current location, the system changes its state to standby and the state of the standby process on the new location to active.
To keep the system stable, do not perform any tasks that require process restart when you execute this command.
Examples
# (In IRF mode.) Reoptimize process placement.
