That is only 16421 bytes are occupied, but the system says that 194448 bytes are occupied!

On this Cisco, everything is fine, that is, there is a lot of free space.

Why on Cisco #1 all memory is full?

Hi,

Do these switches run the same IOS version?

Also, is there enough space in flash?

What is the output of "dir" or "sh flash" on each switch?

HTH

Hi! Thank for reply.

I'll take some gueses. Perhaps one is formatted with the more "modern" FAT16/FAT32 and the other with Cisco's older original filesytsem.

My next guess is filesystem damage. Try using fsck to fix it.

I don't understand why you are talking about flash memory when it comes to NVRAM?

>I don't understand why you are talking about flash memory when it comes to NVRAM?

Does this model actually have NVRAM? Isn't it simulated in flash?

Why don't you try making a copy of the files that you can, formatting NVRAM and then putting them back.

Command format only applies to flash:. What then is the nvram: formatting command?

Try one of these:

erase nvram:

format nvram:

I found out that we have several devices with this problem.

I executed the command, but as you can see the free space did not increase and the files were not deleted.
