Parameters
slot slot-number: Specifies an IRF member device by its member ID or a PEX by its virtual slot
number. If you do not specify this option on an IRF fabric, the command displays memory usage on
all member devices. If you do not specify this option on an IRF 3 system, the command displays
memory usage on all parent devices and PEXs.
cpu cpu-number: Specifies a CPU by its number. The cpu-number argument must be 0.

Description
ID of an IRF member device or PEX.
Memory usage information.
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 physical memory.
Free physical memory.
Physical memory shared by processes.
Physical memory used for buffers.
Physical memory used for caches.
Free memory ratio.
-/+ 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 memory.
