Usage
Information
The output for show memory displays the memory usage of the line-card processor (LP) part (sysdlp) of
the system. The sysdlp is an aggregate task that handles all the tasks running on the LP.
The total counter size in show memory and show processes memory differs based on which OS
processes are counted.
● In the show memory output, the memory size is equal to the size of the application processes.
● In the show processes memory output, the memory size is equal to the size of the application
processes plus the size of the system processes.

“Lowest” displays the memory usage the system went to in the lifetime of the system. Indirectly, it
indicates the maximum usage in the lifetime of the system: Total minus Lowest.
“Largest” displays the current largest available. This relates to the block size and is not related to the
amount of memory on the system.
