In general, a link aggregation (LAGG) is a method of combining (aggregating) multiple network connections in parallel to provide additional bandwidth or redundancy for critical networking situations.
TrueNAS uses lagg(4) to manage LAGGs.
Before making network interface changes:
Stop running apps.
Power off running virtual machines (VMs) and containers.
Remove active NIC devices for VMs and containers.
Sharing services such as SMB that use the IP address(s) assigned to the primary interface might cause issues with testing network changes.
To resolve issues, stop sharing services such as SMB, change the interface, and test the connection. Restart the service when complete.
A virtual LAN (VLAN) is a partitioned and isolated domain in a computer network at the data link layer (OSI layer 2).
Click here for more information on VLANs.
Before you begin, make sure you have an Ethernet card connected to a switch port and configured for your VLAN.
Ensure that you have also preconfigured the VLAN tag in the switched network.
Consult with your IT department to obtain this VLAN tag if you are not the network administrator for your systems.
The Static Routes widget on the Network screen displays static IP addresses configured as static routes. Use this to manually enter routes to network destinations outside the TrueNAS network so the router can send packets to a destination network.
TrueNAS does not have defined static routes by default.
If you need a static route to reach portions of the network, add the route by going to Network and clicking Add in the Static Routes window.
TrueNAS does not pre-define static routes by default, but TrueNAS administrators can manually add static routes if they want or need to enter routes to a router to send packets to a destination network.
Static routes are not aliases, they are fixed IP addresses assigned as alternative routes for network traffic sent to a specific destination (server, device) in the network.
You can use the Console Setup menu during installation or any time after the initial system configuration to add a static route through an SSH session or by connecting a monitor and keyboard to the system, but we recommend using the web UI to make changes to the network configuration.
Follow these best practices for a stable and performant network.

Static IP Address
By default, TrueNAS configures the primary network interface for Dynamic Host Configuration Protocol (DHCP) IP address management.
Consider assigning a static IP address for increased network stability and communication between devices.
IPMI requires a compatible motherboard with IPMI support.
Refer to your hardware documentation to determine compatibility.
Many TrueNAS systems include a built-in out-of-band management port, enabling system access even when the web interface is unavailable.
Intelligent Platform Management Interface (IPMI) allows users to check the log, access the BIOS setup, and boot the system without physical access.
IPMI also enables users to remotely access the system to assist with configuration or troubleshooting issues.
Configuring TrueNAS to work with virtualized features, such as virtual machines (VMs) and applications, is part of the setup process that, when optimized, takes advantage of the network storage capabilities that TrueNAS offers.
Before You Begin
This article assumes you have the latest release version of TrueNAS installed on your system.
The following steps are a list of configuration prerequisites you have completed and are familiar with before beginning VM and application installations.
