Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command
displays memory usage for all user processes on the active MPU. (Distributed devices in standalone
mode.)
slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member
device, this command displays information for the master device. (Centralized devices in IRF mode.)
chassis chassis-number slot slot-number: Specifies a card on 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 card. If you do not specify a card, this command displays
information for the global active MPU. (Distributed devices in IRF mode.)
cpu cpu-number: Specifies a CPU by its number. (Centralized devices in IRF mode/distributed
devices in IRF or standalone mode.)
Usage guidelines
When a user process starts, it requests the following types of memory from the system:
• Text memory—Stores code for the user process.
• Data memory—Stores data for the user process.
• Stack memory—Stores temporary data.
• Dynamic memory—Heap memory dynamically assigned and released by the system
according to the needs of the user process. To view dynamic memory information, execute the
display process memory heap command.
