[Sandeep Choudhary]

If you want to download Software from TFTP server to swicth then you nee dto use this command:

archive download-sw /leave-old-sw tftp://10.85.65.13/<image>.tar

Here is a post about it:

How to verify md5 on swicth:

but it has a d/f md5 so please let me know   how to find out the ios through md5 in cisco site.

Hi Sandeep,

  I have gone to cisco site and downloaded software according to   this

Switch Ports Model              SW Version            SW Image
------ ----- -----              ----------            ----------
*    1 30    WS-C3750X-24       15.0(1)SE3            C3750E-UNIVERSALK9-M

But the software I get has a diff md5 value as I compare with the switch current image

link from I get ios ->>>> https://software.cisco.com/download/release.html?mdfid=282979363&softwareid=280805680&os=&release=15.0.2-SE11&relind=AVAILABLE&rellifecycle=&reltype=latest&i=!pp

Also find the screenshot and check whether I downloaded the right software or not..?

It means the file does not exist in the root directory.  

Post the complete output to the command "dir".

Hi Leo,

After shooting this command I able copy ios image from switch to tftp .

cd flash:/c3750e-universalk9-mz.150-1.SE3
copy flash:c3750e-universalk9-mz.150-1.SE3.bin tftp:
Address or name of remote host []? 10.85.65.13
Destination filename [c3750e-universalk9-mz.150-1.SE3.bin]?

But after copying of 900 bytes connection automatically close that is mostly happening at that time when I login switch through ssh it get close when I put the putty in idle state and not typing anything for two to three minutes.

[Leo Laohoo]

I really don't understand why you want to copy the IOS from a switch when you can download the same IOS from the Cisco website.

[yogesh1]

Hi Leo,

It just a doubt that why its not working and I have gone to cisco site and downloaded software according to   this

Switch Ports Model              SW Version            SW Image
------ ----- -----              ----------            ----------
*    1 30    WS-C3750X-24       15.0(1)SE3            C3750E-UNIVERSALK9-M

But the software I get has a diff md5 value as I compare with the switch current image

link from I get ios ->>>> https://software.cisco.com/download/release.html?mdfid=282979363&softwareid=280805680&os=&release=15.0.2-SE11&relind=AVAILABLE&rellifecycle=&reltype=latest&i=!pp

Also find the screenshot and check whether I downloaded the right software or not..?

Hi

Check if the window firewall is disabled or other software like antivirus. Also check these lines:

  49  drwx         512   Mar 1 1993 05:34:17 +05:30  c3750e-universalk9-mz.150-1.SE3

%Error reading flash:c3750e-universalk9-mz.150-1.SE3 (Is a directory), You cannot export a folder so you should verify what is inside of the folder, 

dir flash:c3750e-universalk9-mz.150-1.SE3

and you will see the file .bin.

So to copy that it should see something like

flash:c3750e-universalk9-mz.150-1.SE3/c3750e-universalk9-mz.150-1.SE3.bin

Hi Yokesh,

I hope the IOS file is stored in the subdirectory "c3750e-universalk9-mz.150-1.SE3" and not directly in flash.

So we need to give the exact path and filename for this. Please try the below

Tech-C2-FCore01#copy flash tftp:
Source filename [c3750e-universalk9-mz.150-1.SE3]?c3750e-universalk9-mz.150-1.SE3/c3750e-universalk9-mz.150-1.SE3.bin
Address or name of remote host []? 10.85.65.11
Destination filename [c3750e-universalk9-mz.150-1.SE3]?
