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:

ajb_udpi_path

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:

fdpi_ctrl setenv --ajb_save_url  1
fdpi_ctrl setenv --ajb_save_udpi 1

Enabling PCAP recording:

fdpi_ctrl load --service 12 --ip 192.168.1.1
fdpi_ctrl load --service 12 --login USER101 

Disabling:

fdpi_ctrl del --service 12 --ip 192.168.1.1
fdpi_ctrl del --service 12 --login USER101

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:

ajb_pcap_ind_mask=1

Where:

• 0 - index is not created (default)
• 1 - by IPv4
• 2 - by IPv6
• 3 - by IPv4 and IPv6

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:

span_vlan=123

For diagnostics, you can use one of the parameters in fastdpi.conf:
These are hot parameters, enabled and disabled with reload

trace_ip
span_trace
ajb_save_emit

Enabling VLAN mirroring:

fdpi_ctrl load --service 17 --ip 192.168.1.1
fdpi_ctrl load --service 17 --login USER101 

Disabling VLAN mirroring:

fdpi_ctrl del --service 17 --ip 192.168.1.1
fdpi_ctrl del --service 17 --login USER101
