# Add Ethernet Interface

Additional Ethernet interfaces can be added and configured when an additional physical interface is added. This can occur during a Nodegrid Manager installation, where the System might have more than two interfaces to better support network separation.

1. Go to the *NETWORK::CONNECTIONS*page
2. Click **Add** (displays dialog)
3. Enter **Name**
4. On **Type** drop-down, select **Ethernet**(dialog changes)

5. Enter **Description**
6. If the **Connect Automatically** checkbox is selected, the connection is automatically established at startup
7. **Set as Primary Connection** checkbox (defines interface as the primary connection. Only one interface can be the primary.)
8. If **Enable LLDP advertising and reception through this connection** checkbox is selected. On the **Port ID** drop-down, select one. On **Port Description** drop-down, select one

9. Select the **Block Unsolicited Incoming Packets** checkbox (automatically blocks all inbound connections on the interface).
10. In the *Ethernet Connection* menu, on the **Link Mode**drop-down (availability depends on the interface and the device model), enable the **Auto**selection or select the forced or advertised speed/duplex (options vary depending upon the hardware and SFP transceiver used). You can navigate to the *TRACKING::NETWORK::INTERFACE* page or execute the command "ethtool *<interface>*" from the shell access to view the configured speed/duplex
11. On the **Enable IP Passthrough**checkbox (expands dialog) enter the details:
  1. **Ethernet Connection** drop-down, select one (selection varies depending on device)
  2. **MAC Address** (if blank, the system uses DHCP to get the device)
  3. **Port Intercepts** (any ports that should NOT pass through the Nodegrid device)
12. In *IPv4 Mode*menu, enter details:
  1. **No IPv4 Address** radio button
  2. **DHCP** radio button
  3. **Static** radio button (if selected, expands dialog). Enter **IP Address**, **BitMask**. and (optional) **Gateway IP**

  4. (optional) **IPv4 DNS Server**
  5. **IPv4 DNS Search** (defines a domain name for DNS lookups)
  6. **IPv4 Default Route Metric**
  7. **Ignore obtained IPv4 Default Gateway** checkbox
  8. **Ignore obtained DNS server** checkbox
13. In *IPv6 Mode*menu, enter details:
  1. **No IPv6 Address** radio button
  2. **Link local Only** radio button
  3. **Address Auto Configuration** radio button
  4. **Stateful DHCPv6** radio button
  5. If **Static** radio button is selected (displays menu). Enter **IP Address**, **Prefix Length**, and (optional) **Gateway IP![](https://cdn.document360.io/763c5fb1-b9af-4ccd-9ad6-cf28ae4cd5a3/Images/Documentation/image-1678380303006.png)**
14. (optional) Enter **IPv6 DNS Server.**
  1. **IPv6 DNS Search** (defines domain name for DNS lookups)
  2. **IPv6 Default Route Metric**
  3. **Ignore obtained IPv6 Default Gateway** checkbox
  4. **Ignore obtained DNS server** checkbox
