Field Descri
p
tion
Total
Total size of the physical memory space that can be allocated.
The memory space is virtually divided into two parts. Part 1 is solely used for kernel
codes, kernel management, and ISSU functions. Part 2 can be allocated and used for
such tasks as running service modules and storing files. The size of part 2 equals the
total size minus the size of part 1.
Used Used physical memory.
Free Free physical memory.
Shared Physical memory shared by processes.
Buffers Physical memory used for buffers.
Cached Physical memory used for caches.
FreeRatio Free memory ratio.
-/+ buffers/cache
-/+ buffers/cache:used = Mem:Used – Mem:Buffers – Mem:Cached, which indicates
the physical memory used by applications.
-/+ buffers/cache:free = Mem:Free + Mem:Buffers + Mem:Cached, which indicates
the physical memory available for applications.
Swap Swap memory.
display memory-threshold
Use display memory-threshold to display memory usage thresholds and memory usage notification
statistics.
Syntax
MSR2000/MSR3000:

Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify this option, the command
displays the memory usage thresholds and memory usage notification statistics for the active MPU. (On
an MSR4000.)
cpu cpu-number: Specifies a CPU by its number. If you do not specify this option, the command displays
information about the default CPU.
Usage guidelines
