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.

    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...)
    if I say something that can be taken one of two ways and one of them offends, I usually mean the other one :-)

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

    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
    There is no place like 127.0.0.1
