Just enter N and the image will copy.Īddress or name of remote host ? 100.100.100.1 If it is not, it will present a warning asking if you want to abort. Note: on some platforms the system check to see if the image being copied is a valid executable for that system. Now lets copy some IOS to R1 from a remote computer at 100.100.100.25Īddress or name of remote host ? 100.100.100.25 Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms Sending 5, 100-byte ICMP Echos to 100.100.100.2, timeout is 2 seconds: Now, lets use R1 to ping SW1 and R2 to test connectivity For the blog, I will only demonstrate on R2, but since the Switch is IOS, the commands are the same. R1 will be configured as the TFTP server and host files for SW1 and R2 and the network we will be using is 100.100.100.0/24. Well, but configuring your router to act as a TFTP server, you might allow yourself some sleep time instead of watching the !!!!! – and the occasional 000 – go across the screen. What happens if you could A) send a USB drive to the site and have someone plug it in or B) Copy the files necessary to another device and use that to copy the files from? Both of these sound much better then having to upload code in the middle of the night. Most of us tend to pre-load the code on the devices in preparation for the upgrade, but what happens when you have insufficient space on the device you need to upgrade? Typically that means performing the IOS transfer when you are doing the upgrade and not before – that is usually during sleeping hours and not business hours. Have you ever need to upgrade the IOS on a remote device? Happened to have more then one of those at a remote site? Have multiple devices at a site to upgrade? I am sure we have all been there at one time or another with one or all of these scenarios. Since I did mention that, it makes sense to post on how to use a router for this functionality. The other day I mentioned about using a router as a TFTP server to upgrade other devices.
