There are two ways this can be done.
- Installing it from TFTP server
- Web Interface
Warning. While it would seem like the web interface should work better, I find it doesn’t work more often than not.
I will be performing this on a Cisco 2960 switch but the theory should work for almost any Cisco product. Here is some info regarding my test lab setup:
- Make note of your switch IP address as well as the IP address of the TFTP server.
- My switch’s IP address is: 192.168.101.4
- My TFTP servers IP address is: 192.168.101.100
- I use SolarWinds TFTP server.
- For Console application I use putty.
Installing Cisco IOS 15 from a TFTP server
Here is some of the screenshots in order:
Run “enable” and then ping the TFTP server.
Copy the file to Flash. It’s a good idea to copy the name of the .bin file in Windows Explorer. To insert it into putty use “Shift+insert”.
Look at your flash. Verify that the file has been copied
Tell it where to boot from the image and save running configuration. Please note that I typed:
“boot system flash:c2960-lanbasek9-mz.150-2.SE2.bin”
The first time I used this command I didn’t know that you had to use the “:” inbetween flash and the filename.
reload the switch. You should notice that it loads the new .bin file.
Run show version to verify that it is installed correctly.
