WeOSNon Redundant ECSP Services HowTo
This document describes how to configure the ECSP services in a non redundant train setup. The consists are depicted in Figure 1.
The result of the inauguration will be a network where ETBN1 in consist 1 has ETBN-ID 1, the IP-address 10.128.0.1 (based on the ETBN-ID and since the network is configured as TCMS). ETBN1 in consist 2 will attain ETBN-ID 2 and IP 10.128.0.2. CN1 in consist 1 will attain the network IP 10.128.64.0/18, and CN1 in consist 2 IP 10.128.128.0/18.

The first configuration example shows how to configure ETBN1 in consist 1.

Note
In this HowTo, it is assumed that the ETB uses crossover cabling. For this reason, all ETB ports on both ETBNs use the same MDI-X mode. If non-crossover cabling is used, these settings must be changed for two of the inward-facing ETB ports.
Now, repeat the exact steps above in the second ETB node. The only difference is the uuid which now will be uuid 22222222-2222-2222-2222-222222222222.

Communication Profile Configuration
Finally, for the ECSPs to function properly, a communication profile configuration is needed on each node.
cst1 communication profile configuration
cst2 communication profile configuration
Transfer the communication profile configuration file to /cfg/comm-profile.json on each device.
The cst1 configuration file to etbn1cst1. The cst2 configuration file to etbn1cst2.
Note
Ensure the filenames are correct. That is, they should have the name comm-profile.json in /cfg/ on their respective device.
See SCP HowTo for instructions on how to transfer files to the device or use the upload function on the TCN web configuration page.
When the above configuration is complete, the ECSP in cst1 uses IP address 10.0.0.10 on iface vlan10, while the ECSP in cst2 uses IP address 10.0.0.20 on iface vlan10.
To use the ECSP services on cst1, an ECSC client (ECSC1 in figure 1) needs to be running on a host with IP address 10.0.0.42 To use the ECSP services on cst2, an ECSC client (ECSC2 in figure 1) needs to be running on a host with IP address 10.0.0.42 (but connected to the correct consist net of course).
Inauguration Result
Using the show ttdp command we now verify that we have recevied the intended network configuration.
Highlighted in orange are the values that are of interest.

been read. A set of URIs has been choosen to verify that the DNS entries has been created.
