This read-only OCTET STRING holds a short description, up to 32 bytes, of the software set currently in the process of being downloaded to the switch, or of the most recently downloaded set since the last boot. An admin monitoring an in-progress firmware download via TFTP would check this field to confirm the correct software version is actually being transferred. For example, while a firmware upgrade download is running, the admin would poll kxswdisDesc to verify it names the intended new firmware version rather than an unexpected or older file.
