| 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:
|
Command |
Purpose |
Step 1 |
Router#dir bootflash:
|
Displays the contents of boot flash memory, including the names of the images that currently reside there. |
Step 2 |
Router# copy tftp: bootflash:
|
Copies a file from a TFTP server to boot flash memory. |
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:
Directory of bootflash:/
1 -rw- 3173128 cat2948g-in-mz.120-7.W5.14.45
