IOS version assistance

[PaulMThomas]

I have a Cisco Catalyst 3750G-24-TS switch which is a cluster master.

Recently installed new IOS (Version: c3750-ipservicesk9-tar.122-35.SE2.tar)

I would like to install the latest IOS available that will fit into the 16mb Flash on this device.

In Windows it shows c3750-ipservicesk9-tar.122-53.SE2.tar as a size of 15,851,520 bytes.
On the switch it shows that 15,996,416 bytes are free in flash.

Yet when I try and upload the image it says there isn't sufficient space in flash....

Any ideas/suggestions? What am I missing? Can I easily upgrade the flash?

Flash is not upgradeable on these boxes. All images will fit but with 16 meg you can only have 1 image at a time in flash , so the question is how adventuresome are you ? You can use the overwrite command when you do the archive function and that should overwrite the existing image and or directory .

I did delete the existing image file and subdirectories, to the point it showed 15,996,416 bytes free in the flash, but te 15,851,520 image wouldn't install as per message above

then only tftp the bin file to the switch
you shouldn't have to use the webpages to access the switch (=is within the tar).
telnet should be enough.

yes, get the ".bin" file which should probably be less in size. for a file that big, i prefer to use tftp32 rather than pumpkin. sometime CiscoWorks works pretty good in running jobs like IOS upgrade.
