Uploading IOS Image

Unanswered Question
Mar 27th, 2008

Hello,

Can someone please take the pain to put me through how to copy the IOS IMAGE from a running 3640 router to a dysfunction one?. I do know how to xmodem but since i do not have the image yet i couldn't do that.

I am using "Solarwinds TFTP server"

Whenever i issued copy flash: tftp the outcome is as follows:

Router1#copy flash: tftp:

Source filename []? router1(i supplied the router name as router1)

Address or name of remote host []? 10.1.1.2 (i gave the address i placed on the tftp server)

Destination filename [router1]? c3640-jk9o3s-mz.124-10b.bin ( i supplied the initial output of my sh flash)

%Error opening flash:router1 (No such file or directory)

Router1# ( i was returned to the Priv mode)

I hope with the supplied info, there would be someone out there to help me out.

Please with all courtesy i am asking that this link

http://www.cisco.com/en/US/docs/ios/12_2/configfun/configuration/guide/fcf008.html#wp1001010 is no further sent, otherwise it will give a prospective helper the wrong notion that i have been assisted, instead please guide from where i got stocked.

Thank you all

I have this problem too.

You need to specify not the host name but the file name!

Issue "dir flash:" which you did.

So the correct order would be:

Router1#ping 10.1.1.2 (first check the connectivity)

Then:

Router1#copy flash: tftp:

Source filename []? c3640-jk9o3s-mz.124-10b.bin

Address or name of remote host []? 10.1.1.2

Destination filename [c3640-jk9o3s-mz.124-10b.bin]? c3640-jk9o3s-mz.124-10b.bin

!!!!!!

And then the file should appear on your TFTP server.

Hope this helps.

Hi

I think you are trying to copy the image of a exiting router IF so

The should be

Router1#copy flash: tftp:

Source filename: should be the file that you want to copy (c3640-jk9o3s-mz.124-10b.bin)

Address or name of remote host: your tftp server ip (10.1.1.2)

Destination filename: can be any thing (default will be same as Source filename)

Do rate if it help

Hello,

I am most delighted for your help even though i am not yet home to see how it goes, but can't wait to thank whoever's willing to help me on this mystery.

Further to this i am still puzzled by how the router will know how to locate the TFTP server, knowing well that this is just a mere software.

Your explanations will be terabytically apprecited on this too.

Thanks

Router locates TFTP server by the IP address you are entering. By specifying 10.1.1.2 you're telling router that TFTP server is running on Server 10.1.1.2.

The router knows TFTP protocol (it has this application in IOS) and runs it. It connects to UDP port 69, which was specifically assigned by IANA.

Here are all the ports that have been officially assigned:

Hello,

further to my recent inquiry on "TFTP", this is the result of my attempt which i hope would help you (anyone) out there help further. The error reports now says timed out. Please have a look at the under-listed output from my Router.

Router1#copy flash: tftp:

Source filename [c3640-jk9o3s-mz.124-10b.bin]?

Address or name of remote host []? 10.1.1.2

Destination filename [c3640-jk9o3s-mz.124-10b.bin]? c3640-jk9o3s-mz.124-10b.bin

.....

%Error opening tftp://10.1.1.2/c3640-jk9o3s-mz.124-10b.bin (Timed out)

Router1#

Thanking you all in advance
