Will the password direct change running config or start config?

When I issue an command to change the password, should I have to "copy run start" to make it persistent?

Thanks,

Of course you do! The router loads the start up config when the router boots so if you don't save the change it won't be present the next time you load the start up config.

When you change the password it will be saved in the running-config of the router (aka the ram). When you do copy run start it will save the password change you did to the startup-config (aka NVRAM). So when you reload your router the password change will be saved.

But the configuration register is not, right? Every time you change it, you don't need to "copy run start" to persist it. This sounds weird to me because config reg is also stored in NVRAM.

Or, is it because the config reg is never loaded into RAM like passwords?

What about the config register? If you change it to bypass the config then it doesn't matter if you saved it or not.

The running config is saved in RAM, which is wiped, Clean, on a reload or restart. When saved [copy run start], it's written into NVRAM while the Running-config still in RAM. - So if you make a mistake on the configuration, restarting will allow you to wipe that problem clean because you didn't save it. We hope. :P

When restarted, the RAM is clean of any configuration (No "running" config). Skipping the NVRAM via register would mean any saved configuration would be skipped, and you'll be brought to the configuration wizard.
