Exciting new features have been introduced with the matured version 1.0 of Canonical’s Netplan utility after more than seven years of development. This major release offers an easier way to configure networking on a Linux system.
The highlights of Netplan 1.0 include the ability to use WPA2 and WPA3 security protocols at the same time, support for using PSK and EAP passwords simultaneously, support for Mellanox VF-LAG for improved SR-IOV networking. Also, new settings for VXLAN tunnels with FRRouting are introduced, namely hairpin and port-mac-learning.
The major release also introduces a new netplan status –diff subcommand that makes it easy to find the differences between configuration and system state. It also has support for identifying bridge/bond/vrf members and for the WPA3-Enterprise security protocol, as well as support for LEAP and EAP-PWD authentication methods.
Going forward, Netplan will have a stable libnetplan1 API without legacy code, which improves the maintainability of its codebase. This release also comes with additional bridge port settings, vastly improved documentation, and numerous bug fixes.
“Those changes pave the way to integrate Netplan into 3rd party projects, such as system installers or cloud deployment methods. By shipping the new python3-netplan Python bindings to libnetplan, it is now easier than ever to access Netplan functionality and network validation from other projects,” said Lukas Märdian, maintainer and lead developer of Netplan, in a blog post.
But Netplan 1.0 includes even more goodies compared to the version used in Ubuntu 22.04 LTS (Jammy Jellyfish), such as support for managing new network interface types like veth, dummy, VXLAN, VRF, or InfiniBand (IPoIB), and integration with NetworkManager on desktop systems.
It also brought improved consistency between supported backend renderers like systemd-networkd and NetworkManager by matching physical network interfaces on permanent MAC addresses when using the match.macaddress setting, as well as new hardware offloading functionality for high-performance networking.
While Netplan 1.0 was released on February 29th, Canonical says that it will be available by default in the upcoming Ubuntu 24.04 LTS (Noble Numbat) operating system series, due out on April 25th, 2024.
Canonical also says that Netplan 1.0 will be available in the forthcoming Debian GNU/Linux 13 “Trixie” operating system series, which should see the light of day in June or July 2024. For more details about the changes included in Netplan 1.0, check out the GitHub release notes.
