Copy Router Firmware in Flash Memory using a TFTP Tool

   In this video presentation we're going to be taking a look at how we go about copying our current cisco iOS or flash from our router over to a tftp server located somewhere in our network now before we get started let's take a look at how I'm set up so that I can make all this happen first things first I got to have a tftp server that is currently installed and configured on a hose somewhere on my network this version of the tftp server that you see in here is a free download from the cisco site currently it has a network ID of 192 168 0 dot 101 that's currently bound to the ethernet adapter onto this machine that is hosting it that's great what we're going to do is we're going to go ahead and ping from my router over to this tftp server to see if I got connectivity so let's do a ping 192 dot one sixty eight dot 0 dot 101 it comes back and it gives me a success rate of one hundred percent I got connectivity from my router to my tftp server now let's verify that I have connectivity from my tftp server over to my router my ethernet interface on the router is currently configured with 192 168 0 dot five and it's on the same subnet mask as my tftp server alright very good if I hit enter it to comes back with a success rate of one hundred percent now I've just about got everything done except the copy procedure so what I'm going to do here now is go back to my router that i'm currently consoled into and i'm going to do a show flash command and the reason I did this because I want to look at the name of my current iOS or my flash and I see that its triple-a 0850 been I'm going to go ahead and copy that and now I'm going to start to ask your procedure of copying over my flash over to my tftp server make sure that the tftp server is up and opened all right and I'm just going to type in copy and if you like to know what you can do with the copy command just use the context-sensitive help just so happens that we're going to be using the flash a part of this syntax so I'm going to type in copy flash space tftp now once i hit enter if everything is working ok it's going to ask me for the source file name now remember we did a copy now I'm going to do a paste that makes it a little easier right the IP address of my remote host that has the tftp server on it now once the destination file name it gives me a default of the current name of the my cisco flash on my iOS i'm going to go ahead and accept that then if you see these ! start flying across the bottom on the screen that means it's working you can also open up your tftp server and you can see it doing this pretty much the same thing now when you see all this happening you've got a pretty good success rate going so far and when it's all done it's just going to say ok and it's all done and that you've actually done a very good copy of your cisco iOS over to your tftp server
