Non 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.

Note that in the diagram below, the nodes are named ETBN1 and ETBN2 respectively, while in the configuration examples below, the device hostnames are etbn1cst1 and etbn1cst2. This is to differentiate between a few concepts: the names in the diagram refer to the local ETBN ID (set using the local-id command), while the hostnames refer to both the local ETBN ID as well as the consist that the node is in.

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 CSTINFO data file is needed on each device. See the Communication Profile documentation for more information about this file and its purpose.

Two such files are provided as examples for this HowTo: CSTINFO data file for consist 1 and CSTINFO data file for consist 2. They are, like the remainder of this document, representative but non-exhaustive examples.

On each node, the CSTINFO data file must be placed in the directory /cfg/ with the name cstinfo.json. This can be done by using any available administrative interface, or by putting the file on the external USB media (in which case it will be available in the /cfg/ directory after rebooting the device).

Note

Ensure the filenames are correct. That is, the file should be named cstinfo.json and placed in /cfg/ on each device.

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).
