| * **''ajb_save_dns''** — flag for writing to a text file.\\ | * **''ajb_save_dns''** — a bit flag that controls whether to log to a text file and enable sending DNS queries via IPFIX. |
| * **''ajb_save_dns=0''** — do not save | * **''ajb_save_dns=0''** — do not save |
| * **''ajb_save_dns=1''** — by default, send DNS responses via IPFIX | * **''ajb_save_dns=1''** — enable saving DNS responses to a file |
| * **''ajb_save_dns=2''** — enables sending DNS queries via IPFIX | * **''ajb_save_dns=2''** — enables sending DNS queries via IPFIX |
