======Management utilities======
=====dpdkinfo=====
Receive diagnostic data from SFP modules. Parameters:
  * ''-h'' – help
  * ''module_eeprom'' – SFP module optical diagnostics information (if supported by the module).

=====bpctl_util=====
Manual bypass control. DPI controls bypass independently, but manual bypass control is performed by this utility if necessary:
  * ''get_bypass'' – get bypass status
  * ''set_bypass on'' – activate bypass
  * ''set_bypass off'' – deactivate bypass
  * ''get_std_nic'' – diagnostic 
  * ''set_std_nic off'' – setting the card to bypass mode (switches the mode to NON-standard mode, i.e. with bypass mode)

=====driverctl=====
DPDK management. Parameters:
  * ''list-overrides'' – check the list of cards in DPDK mode
  * ''unset-override 0000:04:00.0'' – exit the card from the DPDK mode\\ **The fastDPI process must first be stopped with the command ''service fastdpi stop''!**
  * ''-v set-override 0000:04:00.0 vfio-pci'' – return the cards back under DPDK control after working with the standard driver\\ **When switching cards to DPDK mode, be careful not to accidentally switch the server control interface to DPDK mode - communication with the server will be immediately interrupted!**

<note>Configuring DPDK in Hyper-V is described in detail in the appropriate [[en:dpi:dpi_components:platform:dpi_config#configuration_in_hyper-v|section]].</note> 

=====checklock=====
Check if an address or port is blacklisted.\\ Example of a port check:
<code bash>checklock 188.114.97.28</code>

=====checkproto=====
Check if the address or port is included in the custom protocol.\\ Example of a port check:
<code bash>checkproto youtube</code>

=====checknat=====
White address allocation check. Shows how the network for NAT is distributed among process vorkers.\\ 
Command entry format:
<code bash>nthr=x, algo=0|1|2, cidrs='list cidrs' [,tcheck_correct_hash=0:1,gr_cidrs='list gray cidrs',dst_cidrs='list destination cidrs']</code>

Parameters: 
  * ''nthr'' – num work threads per cluster
  * ''algo'' – **0** - hashmask (default), **1** - crc, **2** - rxdsp_2
  * ''cidrs'' – list cidr white address
  * ''check_correct_hash'' – check hash function
    * ''gr_cidrs='list cidr gray address for check' ''
    * ''dst_cidrs='list cidr destination address for check' ''

Examples:
<code bash>
# Example 1
nthr=16 algo=0 cidrs='16.35.120.0/24,91.210.24.128/26'
# Example 2
nthr=16 algo=0 cidrs='16.35.120.0/24,91.210.24.128/26' check_correct_hash=1 gr_cidrs='10.0.0.0/24,192.168.4.0/28' dst_cidrs='30.0.0.0/24,50.0.0.0/24'
