The function depends on the type of device. On devices with USB port this action copies to an inserted memory stick. On a micro switch running from internal memory this action copies to an optional DOS formatted SD card. On all other switch versions this action will do nothing. When applicable this action copies the specified firmware update file (msu) onto the removable media. If the file already exists it is overwritten. Syntax: export_media = u_10_3_3.msu
