Copying a System Image from a TFTP Server to a Bootflash Memory SIMM
You can copy system image files from a TFTP server to the bootflash memory SIMM for use in booting
the Layer 3 switch router.
It is a good idea to have a copy of the current system image on the bootflash 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 bootflash
memory to a TFTP server. You can maintain a known good image as a backup image on the TFTP
server. If the new image file you copy from the TFTP server is corrupted, you can retrieve the known
good backup copy of the system image file from the TFTP server.
