Rosa,

Your switch model (3850-48U) is listed. You can safely ignore the -L, -S, and -E suffixes as they only reflect the license that the devices shipped with. They are all the same hardware. The file you found (cat3k_caa-universalk9ldpe.16.03.05b.SPA.bin) is correct for the latest version as of this writing if you want the non-DTLS version. I'm showing another file as well: cat3k_caa-universalk9.16.03.05b.SPA.bin. The reason the downloaded file and your flash directory are different is due to the new software structure of the 3850 compared to previous switches such as the 3750. The legacy boot mode, called bundle mode, would use the bin file directly from flash. However, it looks like you are in install mode, where the relevant packages are extracted to flash from the bin and loaded based on the contents of the packages.conf file. If you want to upgrade using the file you located, you might enter something like this:

3850# software install file flash:cat3k_caa-universalk9ldpe.16.03.05b.SPA.bin
...
3850# software clean

Hi,

The command to install is:

request platform software package install switch all file flash:cat3k_caa-universalk9.16.03.05b.SPA.bin

Thanks
