    -====== 2 How to troubleshoot the subscriber bandwidth allocation? ====== 
    -{{indexmenu_n>2}} 
    -The absence of bandwidth restrictions indicates there is a problem to solve. 
    - 
    -Add the following option to the /etc/dpi/fastdpi.conf file: 
    -  plc_trace_ip=109.234.130.131 
    -   
    -Reload fastdpi service: 
    - 
    -  service fastdpi reload 
    - 
    -Reload the bandwidth constraints rules: 
    -  fdpi_ctrl load --policing rat_HTB.cfg --ip 109.234.130.131 
    - 
    -Check all the fastdpi policing settings: 
    -  fdpi_ctrl list all --policing 
    -Autodetected fastdpi params : dev='em3', port=29000\\

    -Check the statistics log for the given IP. Not empty log indicates the presence of the traffic, otherwise it indicates that the traffic is not routed through the VAS Experts DPI or the interfaces are not configured properly(in_dev should be oriented towards the subscribers). Let's analyse the stat.log (using the grep output) for the given IP:  
    - 
    -  grep -A 7 "109.234.130.131" /var/log/dpi/fastdpi_stat.log | more

    -Therefore, the outgoing traffic is limited, it is indicated by the non zero Drop entries, so the incoming traffic is routed alternatively and does not fall under the rules loaded in the VAS Experts DPI.
