These tables list the maximum effective data rates, in a single data flow direction, for various data interconnect protocols. A best effort attempt has been made to exclude physical link encoding overheads where appropriate.

Use the Network > Interface Screen to add various network interfaces to your TrueNAS.
Use the COLUMNS button to display options to modify the information displayed in the Interfaces table. Options are Type, Link State, DHCP, IPv6 Auto Configure, IP Addresses, Description, Active Media Type, Active Media Subtype, VLAN Tag, VLAN Parent Interface, Bridge Members, LAGG Ports, LAGG Protocol, MAC Address, MTU or Reset to Defaults.
Use ADD to display the Interface Add screen.
The Interfaces widget on the Network screen displays interface port names and IP addresses configured on your TrueNAS system, as well as their upload/download rates.
Use Add to open the Add Interface configuration screen.
Click on an interface to open the Edit Interface configuration screen.
Click the edit icon next to an interface to open the Edit Interface configuration screen.
Click the refresh icon next to a physical interface to reset configuration settings for that interface.
It is recommended to set up your system connections before setting up data sharing. This allows integrating TrueNAS into your specific security and network environment before attempting to store or share critical data.
Network Summary The Network Summary gives a concise overview of the current network setup. Information about the currently active Interfaces, Default Routes, and Nameservers is provided. These areas are not editable.
Interfaces shows any configured physical bridge, LAGG, and vlan interfaces.
A bridge generally refers to various methods of combining (aggregating) many network connections. These form a single total network. TrueNAS uses bridge(4) to manage bridges.
To set up a bridge interface, go to Network > Interface > Add.
Select Bridge as the Type and enter a name for the interface. The name must use the format bridgeX*, where X is a number representing a non-parent interface. It is also recommended to add any notes or reminders.
Use the Global Configuration Settings screen to add general network settings like the default gateway and DNS name servers to allow external communication.
To add new or change existing network interfaces see Managing Interfaces.
Disruptive Change
You can lose your TrueNAS connection if you change the network interface that the web interface uses! You might need command line knowledge or physical access to the TrueNAS system to fix misconfigured network settings.
The Network screen allows you to add new or edit existing network interfaces, and configure static and alias IP addresses.
Why should I use different interface types? Use LAGG (Link Aggregation) to optimize multi-user performance, balance network traffic, or have network failover protection.
For example, failover LAGG prevents a network outage by dynamically reassigning traffic to another interface when one physical link (a cable or NIC) fails.
Use a network bridge to enable communication between two networks and provide a way for them to work as a single network.
The Network > Global Configuration screen has all the general TrueNAS networking settings that are not specific to any interface.
Disruptive Change
Making changes to the network interface the web interface uses can result in losing connection to TrueNAS! Fixing any misconfigured network settings might require command line knowledge or physical access to the TrueNAS system.
Global Configuration Settings Options are organized into several categories.
Can these options be configured elsewhere?
The Global Configuration widget displays the general TrueNAS networking settings not specific to any interface.
The SCALE information dislplayed the Global Configuration widget is the equivalent of the information displayed on the TrueNAS CORE Network Summary screen. Global Configuration settings configuration screens are similar in both SCALE and CORE but SCALE includes external communication settings. Use Settings to display the Global Configuration screen where you can add or change global network settings.
Use the Global Configuration Settings screen to manage existing general network settings like the default gateway and DNS servers. Set DHCP to assign the IP address or to set a static IP address, add IP address aliases, and set up services to allow external communication.
