# One Consist Network with One ETB Node HowTo

This document describes how to configure a consist with one consist network managed by one ETBN. The consist is depicted in Figure 1.

The result of the inauguration will be a network where ETBN1 has the ETBN ID 1, the IP-address 10.128.0.1 (based on the ETBN ID and since the network is configured as TCMS). CN1 will attain the network IP 10.128.64.0/18.

## 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 10.0.0.1/18
    etbn1:/config/iface-vlan10/inet-static-10.0.0.1/#> end
    etbn1:/config/iface-vlan10/#> end
    etbn1:/config/#> ttdp
    Activating TTDP with default settings.
    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/#> 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

Continue by configuring the ports.

    etbn1:/config/#> port ethX5
    etbn1:/config/port-ethX5/#> speed-duplex 100-full
    etbn1:/config/port-ethX5/#> no auto-negotiate
    etbn1:/config/port-ethX5/#> fastlink
    etbn1:/config/port-ethX5/#> mdix-mode mdi
    etbn1:/config/port-ethX5/#> end
    etbn1:/config/#> port ethX6
    etbn1:/config/port-ethX6/#> speed-duplex 100-full
    etbn1:/config/port-ethX6/#> no auto-negotiate
    etbn1:/config/port-ethX6/#> fastlink
    etbn1:/config/port-ethX6/#> mdix-mode mdi
    etbn1:/config/port-ethX6/#> end
    etbn1:/config/#> port ethX7
    etbn1:/config/port-ethX7/#> speed-duplex 100-full
    etbn1:/config/port-ethX7/#> no auto-negotiate
    etbn1:/config/port-ethX7/#> fastlink
    etbn1:/config/port-ethX7/#> mdix-mode mdi
    etbn1:/config/port-ethX7/#> end
    etbn1:/config/#> port ethX8
    etbn1:/config/port-ethX8/#> speed-duplex 100-full
    etbn1:/config/port-ethX8/#> no auto-negotiate
    etbn1:/config/port-ethX8/#> fastlink
    etbn1:/config/port-ethX8/#> mdix-mode mdi
    etbn1:/config/port-ethX8/#> end
    etbn1:/config/#> end
    Applying configuration.
    Configuration activated.
    Remember "copy run start" to save to flash (NVRAM).

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.

## 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.
