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

| Rx UDP Ports | 42820, 42821 | 42822, 42823 | - |
| Flow Control Ports | 42809 | 42810 | - |
| Source IP (Tx) | any | any | - |
| Tx UDP Ports | 42824, 42825 | 42826, 42827 | - |
Table 2: Example Host Computer Network Configuration for Crimson TNG Default Settings
| SFP+ A | SFP+ B | MGMT | |
|---|---|---|---|
| Host IP Address | 10.10.10.10/24 | 10.10.11.10/24 | 192.168.10.3/24 |
| Net Mask | 255.255.255.0 | 255.255.255.0 | 255.255.255.0 |
| Broadcast | 10.10.10.255 | 10.10.11.255 | 192.168.10.255 |
| MTU | 9000 | 9000 | 1500 |
The destination IP addresses for receive ports may be modified using the web GUI. The default configuration sees information from Rx A sent to the destination IP address of 10.10.10.10.

Footnotes

\(^1\) This is how Crimson TNG ships. If you have any issues or concerns regarding your Micro SD card, please contact us.

\(^2\) It is very important to ensure that network devices or interfaces intended to be used to connect to Crimson TNG support 10GBASE-R. The 10GBASE-R family includes:
- 10GBASE-KR,
- 10GBASE-SR,
- 10GBASE-LR,
- and 10GBASE-ER interfaces.
There is a significant difference between a 10GBASE-X interface (4 serial lanes specified to 3.125Gbps using 8b/10b coding), and the 10GBASE-R interface (1 serial lane specified to 10.3125Gbps using 64b/66b coding) that Crimson TNG uses.
Although both standards may expose the same mechanical SFP+ interface (and thereby allowing you to mechanically connect the two interfaces) the standards are fundamentally incompatible. Connecting Crimson TNG (10GBASE-R) to a network card that only supports 10GBASE-X or 10GBASE-T will not work.
