Why should I use different interface types? expand LAGG (Link Aggregation)
You should use LAGG if you want 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.
In general, a bridge refers to various methods of combining (aggregating) multiple network connections into a single aggregate network. TrueNAS uses bridge(4) as the kernel bridge driver. Bridge(8) is a command for configuring the kernal bridge in Linux. While the examples focus on the deprecated brctl(8) from the bridge-utilities package, we use ip(8) and bridge(8) from iproute2 instead. Refer to the FAQ section that covers bridging topics more generally.
To set up a bridge interface, from the Network screen:
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.
To set up a LAGG, from the Network screen:
Click Add in the Interfaces widget. The Add Interface configuration screen displays.
Select Link Aggregation from the Type dropdown list. You cannot change the Type field value after you click Apply.
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. TrueNAS uses vlan(4) to manage VLANs.
Before you begin, make sure you have an Ethernet card connected to a switch port and already configured for your VLAN. Also that you have preconfigured the VLAN tag in the switched network.
To set up a VLAN interface, from the Network screen:
TrueNAS does not have defined static routes by default but TrueNAS administrators can use the Static Routes widget on the Network screen to manually enter routes so a router can send packets to a destination network.
If you have a monitor and keyboard connected to the system you can use the Console setup menu to configure static routes during the installation process, but we recommend using the web UI for all configuration tasks.
DHCP or Static IP? One Static IP Address or Multiple Aliases? Before you Begin Changing to a Static IP Address Returning to DHCP from Static IP This article provides instructions on setting up a network interface with a static IP address or changing the main interface from a DHCP-assigned to a manually-entered static IP address. You must know the DNS name server and default gateway addresses for your IP address.
