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
memory SIMM (also referred to as bootflash) while the system is running from onboard
Flash memory.
Note
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.
