# Non redundant ECSP services HowTo

This document describes how to configure the ECSP services in a non redundant train setup.

See Figure 1 below

           /  UUID1  \  /  UUID2  \

          --+       +----+       +--     dir1 = (ethX5, ethX6)
      <-dir1| etbn1 |    | etbn2 |dir2-> dir2 = (ethX7, ethX8)

## Configuration

    etbn1:#> configure
    etbn1:/config/#> vlan 10
    Creating new VLAN vid:10 with name: vlan10
    etbn1:/config/vlan-10/#> untagged ethX3
    etbn1:/config/vlan-10/#> end
    etbn1:/config/#> iface vlan10
    etbn1:/config/iface-vlan10/#> no inet
    etbn1:/config/iface-vlan10/#> inet static 10.0.0.10/18
    etbn1:/config/iface-vlan10/inet-static-10.0.0.10/#> end
    etbn1:/config/iface-vlan10/#> end
    etbn1:/config/#> ttdp
    Activating TTDP with default settings.
    DNS Server activated
    etbn1:/config/ttdp/#> uuid 11111111-1111-1111-1111-111111111111
    etbn1:/config/ttdp/#> node 1 ecn 1
    etbn1:/config/ttdp/#> ecn 1 vlan10
    etbn1:/config/ttdp/#> dir1 ethX5,ethX6
    Remember to manually set mdi/mdi-x mode
     in port settings for all agg ports.
    etbn1:/config/ttdp/#> dir2 ethX7,ethX8
    Remember to manually set mdi/mdi-x mode
     in port settings for all agg ports.
    etbn1:/config/ttdp/#> local-id 1
    etbn1:/config/ttdp/#> mroute group 239.193.0.1 out 1,etb
    Adding multicast route for 239.193.0.1
    etbn1:/config/ttdp/#> ecsp-iface vlan10
    etbn1:/config/ttdp/#> ecsp-addr 10.0.0.10
    etbn1:/config/ttdp/#> ecsc-addr 10.0.0.42
    etbn1:/config/ttdp/#> end
    TTDP: Created VLAN 492. Note that this VLAN will not be deleted automatically
      if TTDP is deactivated.
    etbn1:/config/#> vlan 2
    Creating new VLAN vid:2 with name: vlan2
    etbn1:/config/vlan-2/#> no multicast-snooping
    etbn1:/config/vlan-2/#> untagged lag-dir1,lag-dir2
    etbn1:/config/vlan-2/#> end
    etbn1:/config/#> end
    Applying configuration.
    Configuration activated.  Remember "copy run start" to save to flash (NVRAM**.
    etbn1:/#>

Now, repeat the exact steps above in the second ETB node. For brevity, only the steps that differs will be shown below.

    ...
    etbn2:/config/ttdp/#> uuid 22222222-2222-2222-2222-222222222222
    ...

Note

See Port configuration on how to set MDI/MDIX on the aggregate ports.

## Communication Profile configuration

Finally, for the ECSP’s 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 etbn1. The cst2 configuration file to etbn2.

Note

Ensure the filenames are correct. That is, they should end up with the name comm-profile.json in /cfg/ on their respective device.

See SCP HowTo for instructions on how to transfer files to the 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).
