The following diagram depicts the messaging sequence for client/server negotiation and is a portion of the diagram presented in section 3.1.5.

Figure 5: Messaging sequence for client/server negotiation

Establish an L3 connection: Two devices set up a client/server relationship based on the Connection data exchanged during L2 establishment (see section 3.1.5). To identify the client in the relationship, the devices compare the respective listener intent values and the device with the higher value MUST be designated as the server. When the two values are the same, the devices MUST compare the respective MAC address values and the device with the numerically smaller MAC address MUST be designated as the server. The other device is then designated as the client.

Confirmation of the Handshake data and establishment of the connection are as defined in section 3.1.5.
