upgrading 3560G IOS

Unanswered Question
Jan 18th, 2010

okay, stupid question:

i've upgraded IOS several times on various platforms so i think i kinda know what i'm doing, BUT this one has me stumped.

While the switch is not in production, i want to upgrade the IOS of our new 3560 to the latest so that i don't have to do it when it IS in production, etc.

so i download the latest, started up the TFTP program, etc. and jumped into the switch, found the IOS file and started the upgrade process.

much to my chagrin the upgrade died stating that the file, c3560-ipbase-mz.122-35.SE5, i thought was the IOS is really a folder.

after that i thought well, shoot, c3560-dmon-mz-122-25r.SEB kinda looks like an IOS let's see if i can find an upgrade for that file.  No luck

So the question is which one is the actual, upgrade-able IOS file?

i attached a print shot of the flash files for your reference.

2  drwx         192  Feb 28 1993 18:15:47 -06:00  c3560-ipbase-mz.122-35.SE5
  460  -rwx         104  Feb 28 1993 18:15:48 -06:00  info
  461  -rwx      520080  Feb 28 1993 18:16:01 -06:00  c3560-dmon-mz-122-25r.SEB
  462  -rwx        3359  Jan 18 2010 11:10:17 -06:00  config.text
  463  -rwx           5  Jan 18 2010 11:10:17 -06:00  private-config.text

Thanks, Gary

I have this problem too.

Your output is now complete.  I am interested to know what is the free flash memory left.
What command did you use to upgrade?
What was the error message when the upgrade process failed?

Hello Gary,

It seems that you have extracted the tar archive into your FLASH. The recent IOS tar archives indeed create their own directory in the FLASH and put all the files into that directory, including the IOS image. I believe that your IOS image is inside that directory and so the full path is:

flash:c3560-ipbase-mz.122-35.SE5/c3560-ipbase-mz.122-35.SE5.bin

Would you mind entering the following command in your global configuration mode, saving the configuration and reloading the switch to see if the new IOS boots up?

boot system flash:c3560-ipbase-mz.122-35.SE5/c3560-ipbase-mz.122-35.SE5.bin

Best regards,

Peter

i'm going to try to upgrade the SW thru the Device Manager as much as i don't like using it and will let you know if it works or not.

well, going thru the device mrg. worked.  it's just that normally i download the .bin file and upgrade the SW so this was a new experience.

Thanks for your replies.  Gary
