Understanding Memory Protection 

The XCM8800 provides memory management capabilities. Each process runs in a protected 
memory space. This infrastructure prevents one process from overwriting or corrupting the 
memory space of another process. For example, if one process experiences a loop condition, 
is under some type of attack, or is experiencing some type of problem, that process cannot 
take over or overwrite another processes’ memory space. 

Memory protection increases the robustness of the system. By isolating and having separate 
memory space for each individual process, you can more easily identify the process or 
processes that experience a problem. 

To display the current system memory and that of the specified process, use the following 
command:

show memory process <name> {slot <slotid>}

 

Where the following is true:

name

—Specifies the name of the process.

slot

—On a modular chassis, specifies the slot number of the MSM/MM. A specifies the 

MSM/MM installed in slot A. B specifies the MSM/MM installed in slot B. The number is a 
value from 1 to 8. (This parameter is available only on modular switches.)

The 

show memory process

 command displays the following information in a tabular format: 

System memory information (both total and free)

Current memory used by the individual processes 

The current memory statistics for the individual process also includes the following: 

The module (MSM A or MSM B) and the slot number of the MSM/MM (modular switches 

only) 

The name of the process 

You can also use the 

show memory {slot [slotid | a | b]}

 command to view the system 

memory and the memory used by the individual processes, even for all processes on all 
MSMs/MMs installed in modular switches. The 

slot

 parameter is available only on modular 

switches. 

In general, the 

free

 memory count for an MSM/MM decreases when one or more running 

processes experiences an increase in memory usage. If you have not made any system 
configuration changes, and you observe a continued decrease in free memory, this might 
indicate a memory leak. 

The information from these commands may be useful for your technical support 
representative if you experience a problem.
