====== FastPCRF Management ======
{{indexmenu_n>7}}

The following are the fastPCRF commands, so you have to specify the fastPCRF address in the -r argument of the fdpi_cli utility.

===== Authorization request queue =====
[[dpi:bras_bng:radius_integration:radius_auth_fastpcrf_setup:pending_queue|Authorization request queue]] - is an internal fastPCRF queue, which is designed to smooth out the peaks of calls to the Radius-server. When fastDPI authorization from fastPCRF, it does not take into account the bandwidth of Radius-server. There are parameters in fastpcrf.conf that set the maximum length and time spent in the queue, but sometimes you need to manually clear the queue or view its statistics.

==== pcrf auth queue stat ====
Displays statistics on the internal queue of authorization requests:

<code>
fdpi_cli -r <address> pcrf auth queue stat
</code>

==== pcrf auth queue clear ====
Clears the authorization queue. You can clear the entire queue with the command:

<code>
fdpi_cli -r <address> pcrf auth queue clear
</code>
or the oldest records by specifying the ''time = N'' parameter, where N is the number of seconds, - records older than the specified number of seconds will be removed from the queue:
<code>
fdpi_cli -r <address> pcrf auth queue clear time=60
</code>

===== Persistent reply queue =====
{{anchor:persist_queue}}

[[dpi:bras_bng:radius_integration:radius_auth_fastpcrf_setup:persistent_queue|Persistent queue]] management commands (fastPCRF response queues for authorization requests)

==== pcrf persist queue stat ====
Displays persistent queue statistics for each fastDPI:
<code bash>
> fdpi_cli -r <address> pcrf persist queue stat

Statistics of persist queue (pcrf -> fastdpi):

==== pcrf persist queue clear ====
Clears all queues or only the specified queue.
The command response is the queue statistics after clearing.
<code bash>
   # clears all queues
fdpi_cli -r <address> pcrf persist queue clear

   # clears a queue by its number
   # the queue number can be found from the output of the pcrf persist queue stat command
fdpi_cli -r <address> pcrf persist queue clear 1

   # clears a queue by its name
fdpi_cli -r <address> pcrf persist queue clear 127.0.0.1%lo
</code>

==== pcrf persist queue reconnect ====
Allows you to reconnect to fastDPI without resetting the queue. It can be applied to a specific connection or to all.
