Is Netplan capable of setting link negotiation settings?

  • 772

I set a static IP with Netplan on my desktop, but the link negotiation keeps resetting to "Ignore" every reboot on my Plasma desktop.

How can I make it permanent?

network-manager

    On most Desktops, folks should be adjusting all network settings, including link negotiation, using NetworkManager. You don't specify link negotiation settings in Netplan.

    For these folks, netplan file (/etc/netplan/01-network-manager-all.yaml) is merely a stub handing control over to NM:

    # Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager

    For folks using networkd (usually on servers) instead of NetworkManager, you specify negotiation settings in the .link file, typically in located /etc/systemd/network/ (reference). You don't specify negotiation settings in Netplan.

    AutoNegotiation=

    Takes a boolean. If set to yes, automatic negotiation of transmission parameters is enabled. Autonegotiation is a procedure by which two connected ethernet devices choose common transmission parameters, such as speed, duplex mode, and flow control. When unset, the kernel's default will be used.

    Note that if autonegotiation is enabled, speed and duplex settings are read-only. If autonegotiation is disabled, speed and duplex settings are writable if the driver supports multiple link modes.
