NVRAM provides 2 MB of memory for system configuration files, software configuration register

settings, and environmental monitoring logs. This information is backed up with built-in lithium

batteries that retain the contents for a minimum of 5 years. NVRAM is not user configurable or field

Flash Memory

Flash memory allows you to remotely load and store multiple Cisco IOS software and microcode images.

You can download a new image over the network or from a local server and then add the new image to

Flash memory or replace the existing files. You then can boot the routers either manually or

automatically from any of the stored images.

Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to

boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash

memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS

software image.
