Syntax Description
Command Modes Exec
Command History
Usage Guidelines The show memory fast command displays the statistics for the fast memory. “Fast memory” is another
name for “processor memory,” and is also known as “cache memory.” Cache memory is called fast
memory because the processor can generally access the local cache (traditionally stored on SRAM
positioned close to the processor) much more quickly than main memory or RAM.
Note The show memory fast command is a command alias for the show memory processor command. These
commands will issue the same output.
Examples The following example shows sample output from the show memory fast and the show memory
processor commands:
