P_DATA_V1 – Data channel packet containing data channel ciphertext. P_DATA_V2 – Data channel packet containing peer-id and data channel ciphertext. Session IDs and Key IDs. OpenVPN uses two different forms of packet identifiers: The first form is 64 bits and is used for all control channel messages. This form is referred to as a session_id.

OpenVPN Protocol | OpenVPN OpenVPN * uses two different forms of key_id. The first form is 64 bits * and is used for all P_CONTROL messages. P_DATA messages on the * other hand use a shortened key_id of 3 bits for efficiency * reasons since the vast majority of OpenVPN packets in an * active tunnel will be P_DATA messages. OpenVPN / [Openvpn-devel] [PATCH] Peer-id patch Added new packet format P_DATA_V2, which includes peer-id. If server supports, client sends all data packets in the new format. When data packet arrives, server identifies peer by peer-id. peer-id-v2.patch on Ticket #49 – Attachment – OpenVPN
