Copying Files to Flash Memory

Copying a new Cisco IOS software image to Flash memory might be required whenever a new

Cisco IOS software release or maintenance release becomes available. Copying a system configuration file might also be required if you want to keep a backup copy of it. Use the information in this section to copy any type of file to Flash memory.

Caution In general, we recommend that you upgrade Cisco IOS software images in Flash memory one at a time; do not delete all known-good images at one time. Also, upgrade Flash memory or Flash disks separately from onboard Flash memory to avoid losing important Cisco IOS software images that are known to be good. (The onboard Flash memory is referred to as the bootflash.)

Note If using an ATA Flash disk, replace any commands that include a slot0: or slot1: command argument with a disk0: or disk1: command argument.

Use the command copy tftp:filename [bootflash: slot0: slot1:]filename for the copy procedure, where

tftp:filename is the source of the file, and [bootflash: slot0: slot1:]filename is the destination in onboard Flash memory or on either of the Flash memory cards or Flash disks.

An example of the copy tftp:filename command follows:

Router# copy tftp:myfile1 slot0:myfile1

20575008 bytes available on device slot0, proceed? [confirm] Address or name of remote host [1.1.1.1]?

In the preceding example, the exclamation points (!!!) appear as the file is downloaded, and the C characters signify calculation of the cyclic redundancy check (CRC) value, which is a verification that the file has been correctly downloaded to the Flash memory card or Flash disk.
