# jive5ab — Interfaces ## Network Ports | Port | Protocol | Direction | Description | |---|---|---|---| | 2620 | TCP | inbound | MK5 control protocol (Field System commands) | | 4991 | UDP | inbound | VDIF frame receive from VDIFPacker | The VDIFPacker must be configured with `udp.dest_port: 4991` and `udp.dest_ip` pointing to the jive5ab container or host to deliver frames. ## MK5 Control Protocol jive5ab implements the standard Mark5 command set over TCP on port 2620. The Field System issues `record=on` / `record=off` commands to this interface to gate recording. ## Recording Path The recording path inside the container is `/data/`. It is mapped to the host filesystem via the `jive5ab_recording_path` Ansible variable.
