Crimson TNG Network Configuration

Overall Network Configuration

Figure 5: Overall network port configuration procedure.

Crimson TNG boasts three network ports. The Management port is used to configure the device and the two SFP+ ports are used to send data. The default Crimson TNG network values are listed in Table 1. An example of a known functioning client networking configuration is shown in Table 2. Figure 6 has the same information displayed differently.

The Management port is used to configure the device, while the two SFP+ ports are used to send data. Each SFP+ data port is connected to a specific antenna port. To properly configure Crimson TNG, each port must be properly configured.


The Crimson Management port requires connection to an interface that supports half-duplex mode.
