find memory cisco device

I know how to use show mem and show flash

but is there a way to find:


? all in one command.

show memory show the ram right?
of course show flash shows flash

show what is nvram size?

to summarize and please correct me if I am wrong

Nvram is for startup config storage
ram is for both IOS and startup config to run in
flash holds files such as the image .bin and other files

I just would like a command that shows them all
I dont know of any that show nvram size?

    Should probably take a closer look at show ver

    Cisco 2611XM (MPC860P) processor (revision 3.0) with 127308K/3764K bytes of memory.
    Processor board ID JAE0818FEFT
    M860 processor: part number 5, mask 2
    2 FastEthernet interfaces
    32K bytes of NVRAM.
    49152K bytes of processor board System flash (Read/Write)

    Of course what show ver shows can be different from platform to platform

    Cisco WS-C3550-48 (PowerPC) processor (revision Q0) with 65526K/8192K bytes of memory.
    Processor board ID CAT0845Y124
    Last reset from warm-reset
    Running Layer2/3 Switching Image

    The password-recovery mechanism is enabled.
    384K bytes of flash-simulated NVRAM.

    If you're trying to view the actual contents of nvram, use dir nvram: and more nvram:

    32K bytes of flash-simulated non-volatile configuration memory.


    and for the contents:
    S2950-2#dir ?
      /all             List all files

    Huh, you know, it never actually occurred to me to do ? on the dir command to see what my other options were. Thanks mike!

    cisco 2511 (68030) processor (revision D) with 8192K/2048K bytes of memory

    this means RAM right? how do you read exact ram size?

    confused on this what does the ratio mean?

    show processes memory to see what process is using the most memory

    8192K = processor memory
    2048K = i/o memory

    Default is 75%/25%
