Copying Files to a Flash Memory Medium

It is a good idea to copy a new Cisco IOS software image to a Flash memory medium (1) when a new image becomes available or (2) when you want to back up the image.

The information in this section enables you to copy any type of file to the Flash memory SIMM on the RP or to a PCMCIA Flash memory card inserted in either slot 0 or slot 1.

Caution You cannot copy a new Cisco IOS software image into the onboard Flash memory SIMM (also referred to as bootflash) while the system is running from onboard Flash memory.

Note When you upgrade Cisco IOS software images in Flash memory, do so one at a time; it is not good practice to delete all valid images in Flash memory at once. Also, to avoid losing valid Cisco IOS images, you should upgrade PCMCIA-based Flash memory separately from the onboard Flash SIMM on the RP.

To copy a file to Flash memory, issue the following command at the privileged EXEC mode prompt:

Router# copy tftp:filename [ bootflash: slot0: slot1: ]:filename

where:

The argument tftp:filename specifies the source and name of the file to be copied.

The variable [bootflash: slot0: slot1: ]:filename specifies the destination and name of the file to be copied. The option bootflash specifies that the file is to be copied to the onboard Flash memory SIMM on the RP; the option slot0: specifies that the file is to be copied to the PCMCIA Flash memory card in slot 0; the option slot 1: specifies that the file is to be copied to the PCMCIA Flash memory card in slot 1.
