Using the Boot Flash Memory SIMM
Copying a System Image from a TFTP Server to a Boot Flash Memory SIMM
You can copy system image files from a TFTP server to the boot flash memory SIMM for use in booting
the switch router.
It is a good idea to have a copy of the current system image on the boot flash memory SIMM in case
the new image file that you copy from the TFTP server is corrupted.
Note You can also create a backup copy of your system image by copying the system image
from boot flash memory to a Trivial File Transfer Protocol (TFTP) server. You can
maintain a known good image as a backup image on the TFTP server. In case the new
image file you copy from the TFTP server is corrupted, you can then retrieve the known
good backup copy of the system image file from the TFTP server.
Use the following commands to copy the system image from the TFTP server to a boot flash memory
SIMM beginning in privileged EXEC mode:
The following example demonstrates copying a system image from the TFTP server to the boot flash
memory SIMM without erasing the previous image file.
Router# dir bootflash:
