Need help in installing IOS to my 3560 switch.

danlai2004

Dear guys,
i am trying to install a different IOS to my 3550 switch as a practice, but before the installation, i would like to try to back up the current IOS to my TFTP server as a back up, since i am a very beginner of using Cisco switch, i got the following problem that need help.

1. i failed "copy flash tftp: or "archive upload-sw tftp" to back up the current running IOS to my TFTP server. below is the show flash result.

Switch#sh flash

Directory of flash:/

7 drwx 192 Mar 01 1993 00:03:08 c3550-i9q3l2-mz.121-11.EA1

15998976 bytes total (11623936 bytes free)
Switch#

2. as above, c3550-i9q3l2-mz.121-11.EA1 is currently the IOS running in my 3550, but why is
the size so small (only 192 ??) comparing to the IOS that i am going to install to it ?
is this really a IOS or is it the bootup ? since the IOS i am going to install is around 6M in size.

3. what should i do in order that i could copy the current IOS to my TFTP Server as backup?

4. what command should i type in order to download the new IOS to my 3550 swtich from my TFTP server ? is it as simple as "copy tftp flash" and "archive download-sw flash" ??

Thanks Guys !!

I think the c3550-i9q3l2-mz.121-11.EA1 is the directory in which you will find the IOS image. Just like on a regular filesystem.

c3550-i9q3l2-mz.121-11.EA1.bin is the name of the flash file, in the folder c3550-i9q3l2-mz.121-11.EA1 like kpjungle said.

this c3550-i9q3l2-mz.121-11.EA1 is the directory that the file is held in hence your error message....
the file and directory are the same name, the extension is different tho....

you need to move into that directory, using the cd (change directory command) and then copy the file from there.... (it could be in a sub folder in there, but with out the output i can not say...)

srg

Try this for source filename: c3550-i9q3l2-mz.121-11.EA1/c3550-i9q3l2-mz.121-11.EA1.bin

danlai2004

Thanks Srg & laidbackfreak and every one!!!

If they can ping eachother i would tripple-check the tftp-server or maybe try another one.

danlai2004

danlai2004

danlai2004

danlai2004

should the fail reason due to wrong command ? or demaged IOS ?
any advice ?

mgeorge

If you use the "archive "command you must specificy the location and the destination of the tar you are trying to extract

for example

archive tar /xtract tftp://x.x.x.x/c3550-whatever.bin flash:

or you can however just extract the image from the tar and load it to flash directly by doing

copy tftp://x.x.x.x/imagename.bin flash:

it will probably prompt you to erase flash.

If you do it this way you will may have to update the boot paramaters to point to the new image

boot system flash:imagename.bin
