System supports mirroring of signaling and media traffic. This functionality can be used for Lawful Interception. Currently system supports three encapsulation methods:

IP-IP tunnel

:   Original packets will be encapsulated into additional IP-IP
    tunnel header. This mode allows to route mirrored traffic,
    it\'s especially useful when destination equipment not
    available in the same broadcast domain.

IP over Ethernet

:   In this mode original packets will be encapsulated directly
    into Ethernet frame using raw sockets. Intended to use for
    cases when destination equipment is in the same L2 domain.

HEPv3

:   Homer Encapsulation Protocol or HEP is a protocol used to send
    data from a tracing node to a capturing node. The latest
    version of HEP is version 3 which came with a major
    improvement changing HEP protocol from a header based
    encapsulation protocol, that is each field had it\'s well
    known position in the header as it is for the TCP header for
    example, to a more flexible chunk-based protocol.

Sensor and logging level can be chosen in gateway settings. Sensor configuration is separate for A and B leg, thus for both legs mirroring - sensors must be configured for both termination and origination gateway.

Source IP
IP address of source interface of this Sensor. This field is used for "IP-IP encapsulation" mode.
Target IP
IP address of target gateway. This field is used for "IP-IP encapsulation" and for "HEPv3" modes.
Target Port
Port number of target gateway. This field is used for "HEPv3" mode.
Hep Capture
Value of HEP_CAPTURE_ID. Leave it empty to use YETI Node ID as HEP_CAPTURE_ID. This field is used for "HEPv3" mode.
