-====== 2 Configuration ======
-{{indexmenu_n>2}}
-An individual configuration file is used to define each bandwidth control policy. This file specifies bandwidth limits for protocol classes (groups). The method is similar to [[en:dpi:dpi_options:opt_shaping:shaping_settings:start|overall bandwidth control]]).
-[[en:dpi:dpi_components:platform:subscriber_management:start|fdpi_ctrl]] utility applies the configured policies to subscribers.
-The format of the instruction:
-<code>
-fdpi_ctrl command --policing policing_description_file [IP_list]
-</code>
-Instructions' syntax and IP addresses specification methods are described in details here: [[en:dpi:dpi_components:platform:subscriber_management:subsman_cmd:start|Control instructions]].
-<note tip>Note the use of [[en:dpi:dpi_components:platform:subscriber_management:subsman_profiles:start|named policing profiles]]\\
-The tariff plan can be set in [[en:dpi:dpi_options:opt_bandwidth_mgmt:bandwidth_json:start|JSON format]] as well.</note>
-===== Example 1: torrent limiting =====
-We intend to offer our subscribers the plan for 10 Mb/s with torrent bandwidth limit of 3 Mb/s.
-To accomplish the goal we create a class for torrents as described in [[en:dpi:dpi_options:opt_priority:priority_config:start|Configuring priorities]].
-<code>
-bittorrent   cs1
-default      cs0
-</code>
-We split the traffic into 2 classes for this example:
-  * cs0 - corresponds to DSCP=0 QOS(IPP)=0 Best Effort
-  * cs1 - corresponds to DSCP=8 QOS(IPP)=1 Priority
-We create the configuration file rateplan_1.cfg. It specifies bandwidth limits for each of 8 protocol classes (groups). We use HTB (the method of borrowing available bandwidth) and specify the bandwidth limit for torrents 3 Mb, but not smaller than 1 Mb. Unlike torrents, other traffic may take the whole available bandwidth.
-<code bash>
-htb_inbound_root=rate 10mbit
-htb_inbound_class0=rate 8bit ceil 10mbit
-htb_inbound_class1=rate 1mbit ceil 3mbit
-htb_inbound_class2=rate 8bit ceil 10mbit
-htb_inbound_class3=rate 8bit ceil 10mbit
-htb_inbound_class4=rate 8bit ceil 10mbit
-htb_inbound_class5=rate 8bit ceil 10mbit
-htb_inbound_class6=rate 8bit ceil 10mbit
-htb_inbound_class7=rate 8bit ceil 10mbit
-htb_root=rate 10mbit
-htb_class0=rate 8bit ceil 10mbit
-htb_class1=rate 1mbit ceil 3mbit
-htb_class2=rate 8bit ceil 10mbit
-htb_class3=rate 8bit ceil 10mbit
-htb_class4=rate 8bit ceil 10mbit
-htb_class5=rate 8bit ceil 10mbit
-htb_class6=rate 8bit ceil 10mbit
-htb_class7=rate 8bit ceil 10mbit

-  * htp_inbound_root, htb_root are the root classes that define the overall bandwidth for inbound and outbound traffic. The bandwidth is distributed within these classes.
-  * rate - is the minimal bandwidth
-  * ceil - is the maximum bandwidth that can be borrowed from the root class if available
-  * class2-7 would not be used as we configure two classes only: 0 and 1.
-<note warning>The class-speed sum must be less than the root rate.</note>
-Here we assign the configured policy to subscribers that use this plan:
-<code>
-fdpi_ctrl load --policing rateplan_1.cfg --file subscribers_with_rateplan_1.txt
-</code>
-===== Example 2: maximum speed for peering=====
-Bandwidth allocation for several classes (for example containing peer-to-peer traffic) can be deduced from the HTB (Hierarchical Token Bucket) hierarchy. It can be done by specifying the keyword ''static'' in the description. In this case, the restriction for this class will be applied independently regardless to htb_root.
-For example under the conditions noted above, we separately limit the class 6 to 100 Mbps.
-<code bash>
-htb_inbound_root=rate 10mbit
-htb_inbound_class0=rate 8bit ceil 10mbit
-htb_inbound_class1=rate 1mbit ceil 3mbit
-htb_inbound_class2=rate 8bit ceil 10mbit
-htb_inbound_class3=rate 8bit ceil 10mbit
-htb_inbound_class4=rate 8bit ceil 10mbit
-htb_inbound_class5=rate 8bit ceil 10mbit
-htb_inbound_class6=rate 100mbit static
-htb_inbound_class7=rate 8bit ceil 10mbit
-htb_root=rate 10mbit
-htb_class0=rate 8bit ceil 10mbit
-htb_class1=rate 1mbit ceil 3mbit
-htb_class2=rate 8bit ceil 10mbit
-htb_class3=rate 8bit ceil 10mbit
-htb_class4=rate 8bit ceil 10mbit
-htb_class5=rate 8bit ceil 10mbit
-htb_class6=rate 100mbit static
-htb_class7=rate 8bit ceil 10mbit
-</code>
-===== Example 3: assigning policing for multisubscribers =====
-Let us assign the plan from the previous example to a subscriber with several IPs.
-Check that database support is enabled in dpi **/etc/dpi/fastdpi.conf:**
-<code>
-udr=1
-</code>
-If it is not enabled: we enable it and restart DPI: service fastdpi restart
-Reserve for corporative subscriber all his IPs:
-<code>
-fdpi_ctrl load --bind_multi --user OOO_PizzaJohnes:192.168.0.1-192.168.0.5,192.168.1.10-192.168.1.25
-</code>
-The subscriber's IP list can be modified [[en:dpi:dpi_components:platform:dpi_ipmulti:start|dynamically]] (i.e. add new IPs and delete it).
-Assign the bandwidth limits according to the plan:
-<code>
-fdpi_ctrl load --policing rateplan_1.cfg --login PizzaJohnes_LLC
-</code>
-<note tip>For advanced users: We advise to learn how to [[bandwidth_incoming|control outbound traffic via feedback loop]].</note>
