hi all,

are show start and show config commands 100% the same? or are there some minor differences?

Thanks all.

    No such command as show config as far as i know
    show running-config is what is running and wont be used as startup-config until you #copy run start or #wr

    running-config runs in RAM (lost if you turn off device)
    startup-config runs from NVRAM (permanent)

    when I do a show ? on my 2811

    Router# show ?
    configuration Contents of Non-Volatile memory
    running-config Current operating configuration
    startup-config Contents of startup configuration

    and when I do a show config on a factory-reset router, it replies:

    Router# show config
    startup-config is not present
    Router#

    so I *think* show config and show startup are the same. So if this is incorrect, can someone let me know, thanks.

    The startup configuration is stored in NVRAM so "show configuration" and "show startup-configuration" would essentially the same. The running configuration is stored RAM. icon_thumright.gif

    I believe "show config all" will include all of the default commands that are not normally shown when you do a "show start".

    I loaded up two 3725 routers in GNS3, then did show start on one and show config on the other. same output.
