Cisco Firmware Update

Hi Expertise,


I was trying to firmware update to Cisco 3750 stack switches.

I can copy to Flash1: of Switch 1 and successful.

However trying to copy to Flash2:, facing one the issue flash is full. When I check dir flash2 , find out one file 23052009.cfg

Is it safe to delete???

this is a configuration file

this is a configuration file.

someday, you copied the config file to flash

you have switch backups on an external fodler? tftp server?


You can also delete the following files:

- config.txt.backp



but the solution is not that ... because the flash is short (now you have 2MB free and normal ISO need 11MB)... you have to delete the original ISO (c3750-ipservicesk8-mz.122-55.SE5) !


for delete:

delete /force /recursive flash2:c3750-ipservicesk8-mz.122-55.SE5

I agree with Tiago, i.e. that your principle problem is you need to remove the existing IOS image to free sufficient space for the replacement image.  BTW, Tiago has a typo in the name of the existing directory.

Normally, you don't need to worry about tens of KB for some config files, but it appears you have a 3750 with only 16 MB flash.  For those, with later IOS images, flash space can be very tight.
