Configure Ethernet

Configure Ethernet 0

Eth0 is the primary Ethernet interface that is present on all TNA devices. It is used to connect to evalink talos and to configure integrations.

The DHCP client is enabled by default. So, the IP address and all related network parameters are automatically set and you can view them on the TNA Web Server under settings_ethernet Networks > settings_input_hdmi Ethernet 0

info

Access level 3 or above is required to configure Eth0.

If you need to set specific parameters for Eth0, do the following:

1. On the TNA Web Server, navigate to settings_ethernet Networks > settings_input_hdmi Ethernet 0

2. If it is enabled, disable Automatic (DHCP)

3. Fill in the required parameters in the corresponding fields:

• IP address
• Subnet mask
• Gateway
• DNS server 1
• DNS server 2 (Optional)
• DNS server 3 (Optional)

4. Click on Save

5. (Optional) Click Undo changes to reset the parameters to their previous values

Connection Status

The connection status tab is used to check the status of Eth0 by going through 4 checklist steps:

Step	Name	States
1	Ethernet cable	In progress: Checking if an Ethernet cable is connected... Failed: No Ethernet cable is connected Success: The Ethernet cable is connected
2
	Automatic IP configuration	In progress: Getting an IP address... Failed: Failed to get an IP address Success: The IP address is set Note: If no DHCP server is present when DHCP is enabled, this step will stay In progress because the TNA still tries to set an IP address
	Static IP configuration	In progress: Setting the IP address... Failed: Failed to set the IP address Success: The IP address is set
3	Connection availability to evalink	In progress: Connecting... Failed: Failed to connect to evalink (e.g. ports are blocked, the gateway is wrong...) Success: Connection to evalink is available
4	Connection to evalink	In progress: Connecting to evalink... Failed: Failed to establish connection to evalink (e.g. the connection is closed by evalink talos, the TNA is disabled or the instance is not created on evalink talos...) Success: Connection established

Configure Ethernet 1

info

Access level 3 or above is required to configure Eth1.

Eth1 is the secondary Ethernet interface present on ipTNA4i and possible to add using a USB to Ethernet adapter on TNA Connect and TNA connect V2 devices.

Eth1 is used to establish wired connections to isolated private networks without internet access. It can be configured under settings_ethernet Networks > settings_input_hdmi Ethernet 1 on the TNA Web Server.

warning

All connected devices through Eth1 are completely isolated and can only transmit signals to evalink talos unless Port Forwarding is enabled in the Integrations.

IP Configuration

Ethernet 1 must have an assigned IP address and a subnet mask. The default values are 192.168.20.136 for the static IP address and 255.255.255.0 for the subnet mask.

To change the default values, do the following:

1. On the TNA Web Server, navigate to settings_ethernet Networks > settings_input_hdmi Ethernet 1

2. On the IP Configuration tab, enter an IP Address and a Subnet mask in the corresponding fields

3. Click on Save

important

Ethernet 1 must be assigned an IP address that is outside the subnet range of Ethernet 0.

All TNA devices connected to the private network must use IP addresses within the subnet of Ethernet 1 and have the static IP address of Ethernet 1 as a gateway.

As an alternative to static IP address configuration, it is possible to enable the DHCP server for Ethernet 1:

info

Before you enable the DHCP server on Ethernet 1, make sure there is no other DHCP server enabled in the private network.

1. On the IP Configuration tab, toggle Enable DHCP server

2. Click on Save

DHCP Clients

If the DHCP server is enabled on Eth1, the DHCP Clients tab becomes available. This section provides an overview about clients that received DHCP parameters. If the lease time of a client expires, it is removed automatically from the list.

The following information is shown for each DHCP client:

• The assigned IP address

• The client MAC address

• The client name if it is provided

• The lease expiration time

There is an option to assign a static IP address to a particular DHCP client by reserving an IP address for this client. This means that each time the client requests an IP address from the DHCP server, it will provide this reserved IP address. This is useful when a client needs to always have a known IP address.

To reserve a static IP address for a client, do the following:

1. On the TNA Web Server, navigate to settings_ethernet Networks > settings_input_hdmi Ethernet 1

2. Click on DHCP Clients

3. Under Reservations, click on

4. Enter the IP address, the Mac address, and a Description in the corresponding fields

5. Click on Save

You can use the arrow next to any record from the Clients table to copy it to the Reservations table.
