-====== Priority assignment depending on the directions ======
-{{indexmenu_n>4}}
-The direction is defined by a number of an autonomous system that sends or receives the traffic.
-:!: The direction priority specified for autonomous system (if defined) overrides the priority specified by protocol.
-:!: The direction priority specified for the traffic's source (if defined) overrides the priority specified for the destination.
-<note important>One can change the IP list that belongs to an autonomous system and define an auxiliary autonomous system dynamically. It is described in the section [[en:dpi:dpi_options:opt_statistics:statistics_asn:start|Configuring autonomous systems]]</note>
-The direction dependent priorities assigned by the system's administrator, are loaded by DPI from the file **/etc/dpi/asnum.dscp.**
-<note warning>Comments in this file are not allowed!</note>
-This file is created in two steps. First, the text file with a list of autonomous systems and their assigned priorities is created. Next, this file is converted into an internal format by a dedicated utility.
-===== File format of autonomous systems' list and their priorities: =====
-Each line of the file contains: AS_number <space> dscp_value. **For example:**
-<code>
-       cs0
-       local
-       drop
-       pass
-       peer
-</code>
-  * Here cs0 - is [[en:dpi:dpi_options:opt_priority:priority_config:dscp_table|DSCP value]].\\
-Keywords meaning:
-  * drop - means that packets have not to be transmitted: they must be dropped.
-  * pass - the traffic of this autonomous system must go through DPI with no analysis and processing.
-  * local - the traffic of this system is treated as a local operator's one, see [[en:dpi:bras_bng:opt_bras_l3:bras_steps:radius_auth_setup:start|BRAS L3]]
-  * peer - the operator is in peering state with this system; used only for [[en:dpi:dpi_options:opt_cache:start|Cash option]]
-  * term - termination is allowed for this AS; see [[en:dpi:bras_bng:opt_bras_l2:bras_l2_vlan_term:bras_l2_vlan_term_as|BRAS: AS termination]]
-<note important>local, term and peer do not effect the traffic's priority and are used for services. They are described there.</note>
-===== File convertation =====
-To convert this file into the internal format and to place it into the working directory for DPI usage:
-<code>cat my_as_dscp.txt|as2dscp /etc/dpi/asnum.dscp
-service fastdpi reload
-</code>
-<note important>This configuration is loaded on the run, with no need to restart the servic
-===== Configuration for local traffic =====
-To allow the transit of local operator traffic through the DPI without analysing and processing:
-<code>local_passthrough=1</code>
-To place the local operator traffic in a separate class:
-<code>local_dscp=0x38</code>
-dscp is set in a numerical form, the [[en:dpi:dpi_options:opt_priority:priority_config:dscp_table|reference table]] provides correspondence between the numeric and letter symbols.\\
-<note important>local_dscp setting takes precedence over the local_passthrough (if both are specified, the local_dscp is active)</note>
-Autonomous system traffic within its class [[en:dpi:dpi_options:opt_bandwidth_mgmt:bandwidth_conf:start|can be limited]] regardless of the basic service plan limitation.
