This command will copy the running configuration (located in RAM) of a Cisco device to a TFTP server. After executing the command you will be prompted for further information about the TFTP server (Server Address, file name, etc.).
Router(config)#Copy running-config startup-config
This is an incomplete command. However, this indicates that the running configuration will be saved on the device to a different location.
NVRAM
wr or copy running-config startup config
**Switch-6J#
previlage mode i.e hostname#
RouterC#copy running-config tftp [copy run tftp]
It is short for copy running-config starting-config. Running-config is the configuration of the router as you have modified it and which is currently operating, held in RAM (gone after a reboot), and you copy it to the starting-config which is in NVRAM and gets loaded by the router when it boots/ So essentially you're saving what you have now to the persistent storage so your router will still work after a reboot.
it save the current program to nvram
previlage mode i.e hostname#
The difference is that the write mem command is being discontinued. It is being replaced by the copy command and is the one you should use on the cisco tests. I still use this command on some routers such as 831, 871, 3002, 2950, 2600 however it appears that as of IOS 12 it will be gone. Hope this helps!
