placement memory
To set the process memory threshold, use the placement memory command in global configuration or
administration configuration mode. To return the settings to the default value, use the no form of this
command.

Usage Guidelines To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
Use the placement memory command with the maximum value keyword and argument to set the
maximum percentage of memory that can be used on a node (based on the estimated memory usage of
the processes). For example:
•
•
•
Use the placement memory command with the threshold value keyword and argument to set the
preferred percentage of memory use for each node. The system attempts to balance all nodes at or below
the threshold memory percentage. In other words, the system does not place a process on a node that has
exceeded the threshold value, unless all other nodes have also reached their thresholds (or unless some
other large affinity overrides this consideration).

Defines the maximum memory load level. The value is 10 percent to 2000
percent. The default value is 200 percent.
Defines the memory load level to trigger migration. The value is 10 percent
to 400 percent. The default value is 80 percent.
Percent memory load value.
Modification
This command was introduced on the Cisco ASR 14000 Series Router.
The command placement memory maximum 100 sets the maximum memory usage on nodes to
100 percent. If a node has 2 GB of available memory, then only 2 GB of processes can be placed on
the node (estimated memory usage). This means that oversubscription is not allowed.
The command placement memory maximum 50 sets the maximum memory usage on nodes to
50 percent, so that placeable processes can use only half the memory on the node.
The command placement memory maximum 200 would allow the system to attempt to run more
than the available memory on a node.
