    -====== 3 Assigning priorities according to the protocols ====== 
    -{{indexmenu_n>3}} 
    -The protocol priorities (assigned by system administrator) are loaded by DPI from the file **/etc/dpi/protocols.dscp.** 
      
    -This file is created in two steps: first one creates a text file with the list of protocols and their priorities. Second, it is converted into an internal format by a special utility. 
    - 
    -To apply the changes you need to the DPI configuration with the following command: 
    -<code>service fastdpi reload</code> 
    -===== The file format of protocols and priorities list: ===== 
    - 
    -Each line contains the protocol name, then space, then dscp value. **For example:** 
    -<code> 
    -dns         0x3F 
    -skype       drop 
    -compressnet 010 
    -ftp         keep 
    -http        cs0 
    -default     keep 
    -</code> 
    -<note important>[[dpi:dpi_options:opt_statistics:statistics_info:port_proto|Full list of protocols.]]\\ 
    -DSCP value is specified as [[en:dpi:dpi_options:opt_priority:priority_config:dscp_table|decimal, hex or octal number or as a text abbreviation]].</note>  
    - 
    -Keywords meaning: 
    -  * drop - indicates that packets must not be transmitted further. They must be dropped. 
    -  * keep - shows that priority must keep its current value (typically 0). 
    -  * default - means "for all remaining protocols" and allows to simplify significantly making the configuration file. 
    - 
    -===== To convert into an internal format: ===== 
    -<code>cat my_dscp.txt|lst2dscp protocols.dscp</code> 
    - 
    -To move the settings into the work directory: 
    -<code>mv protocols.dscp  /etc/dpi/protocols.dscp</code> 
    - 
    -<note warning>Please use mv instruction! It is an atomic one. Do not use copy!</note>
