-====== PCAP Recording Management and VLAN Mirroring ======
-{{indexmenu_n>4}}
-===== PCAP Recording Management =====
-Service 12 includes PCAP recording for all subscriber traffic. The PCAP file is placed in the path specified in the basic configuration in ''fastdpi.conf'':
-<code bash>ajb_udpi_path</code>
-<note important>In Service 12, PCAP is recorded at the subscriber level, after the processing, policing, and services have been applied to the subscriber.</note>
-When the parameter ''ajb_reserved=1'' is active, you can control the start and stop of the recording on the platform using the SM utility ''fdpi_ctrl'':
-<code bash>
-fdpi_ctrl setenv --ajb_save_url  1
-fdpi_ctrl setenv --ajb_save_udpi 1
-</code>
-Enabling PCAP recording:
-<code bash>
-fdpi_ctrl load --service 12 --ip 192.168.1.1
-fdpi_ctrl load --service 12 --login USER101 </code>
-Disabling:
-<code bash>
-fdpi_ctrl del --service 12 --ip 192.168.1.1
-fdpi_ctrl del --service 12 --login USER101
-</code>
-To quickly search for data in the PCAP file, you can create a file with indexable data by enabling the setting in ''/etc/dpi/fastdpi.conf'':
-<code bash>
-ajb_pcap_ind_mask=1
-</code>
-Where:
-  * 0 - index is not created (default)
-  * 1 - by IPv4
-  * 2 - by IPv6
-  * 3 - by IPv4 and IPv6
-<note important>If other recording methods for the same subscriber, ''ajb_save_udpi'' or ''ajb_save_ip'', are enabled, the resulting index will not write ''SESSION_ID''</note>
-<note>The minimum PCAP file size is 100 MB</note>
-===== VLAN Mirroring =====
-Service 17 includes mirroring subscriber traffic to a specific VLAN, which is added to the data ports of SSG. The traffic direction is preserved.
-Configuration in ''fastdpi.conf'':
-<code bash>
-span_vlan=123
-span_trace=1
-</code>
-For diagnostics, you can use one of the parameters in ''fastdpi.conf'':
-<code bash>
-trace_ip
-span_trace
-ajb_save_emit
-</code>
-Enabling VLAN mirroring:
-<code bash>
-fdpi_ctrl load --service 17 --ip 192.168.1.1
-fdpi_ctrl load --service 17 --login USER101 </code>
-Disabling VLAN mirroring:
-<code bash>
-fdpi_ctrl del --service 17 --ip 192.168.1.1
-fdpi_ctrl del --service 17 --login USER101
-</code>
-<note important>If both services 12 and 17 are enabled, the PCAP will show both the original and mirrored recordings.</note>
