Cisco IOS devices typically use their flash memory to store the IOS image.On most routers, this flash memory can be easily replaced.Here is the topology I will use: There are two things we can do to supply a username and password.

One thing you might have to deal with is authentication.

Most FTP servers will require a username and password.

I have triple checked the file name and pretty sure it is correct. Another issue I notice is that, after I have set the boot system to the newer IOS (and verified it with "show boot"), when I reload, it is still booting the old IOS.

I then tftp the same file to another 2960 and it verified without any issue. I have to manually delete old IOS and reboot it again before it picks up the new one.

You can download it for free and it’s an executable, no need to install anything. Here’s how to copy the current IOS image to the TFTP server: ?

Once you downloaded TFTPD32, start it: And you will see the main screen: Make sure you select the correct directory where you downloaded your IOS image and if you have multiple network interfaces, select the correct interface. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 67926080 bytes copied in 312.508 secs (217358 bytes/sec) When you use the copy flash: tftp: command, it will ask you for the IP address and filename.I will use a Cisco 2800 IOS router in these examples.First, head over to Download and grab the IOS image that you want.It’s also possible to supply a username and password with the copy command. Accessing ftp://*****:*****@192.168.1.201/c2800nm-adventerprisek9-mz.151-4. Last but not least, we have SCP (Secure Copy) which uses SSH.Here is an example: R1#copy ftp://admin:[email protected]/c2800nm-adventerprisek9-mz.151-4. M12flash: Destination filename [c2800nm-adventerprisek9-mz.151-4. This is a great method because of two reasons: R1(config)#ip domain-name NETWORKLESSONS. 67929600 bytes copied in 884.704 secs (76782 bytes/sec) The copy command will ask for the remote IP address, username, password, and filename.Don’t type “y” or “yes” here or that will become the destination filename. Accessing tftp://192.168.1.200/c2800nm-adventerprisek9-mz.151-4. If you have to upgrade the IOS image on multiple devices, this is more convenient as you can just copy/paste the above line on all devices.
