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!

Configuring DPDK in Hyper-V is described in detail in the appropriate section.

Command entry format:

nthr=x, algo=0|1|2, cidrs='list cidrs' [,tcheck_correct_hash=0:1,gr_cidrs='list gray cidrs',dst_cidrs='list destination cidrs']

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:

# 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'
