; }; Talos Linux allows you to configure Ethernet network link settings, such as ring configuration or disabling TCP checksum offloading. The settings and their values closely follow `ethtool` command line options, so you can use similar recipes. ## Observing current status You can observe current Ethernet settings in the `EthernetStatus` resource: ```yaml theme={null} # talosctl get ethernetstatus enp0s2 -o yaml spec: rings: rx-max: 256 tx-max: 256 rx: 256 tx: 256 tx-push: false rx-push: false features: tx-scatter-gather: on tx-checksum-ipv4: off [fixed] tx-checksum-ip-generic: on tx-checksum-ipv6: off [fixed] highdma: on [fixed] tx-scatter-gather-fraglist: off [fixed] tx-vlan-hw-insert: off [fixed] rx-vlan-hw-parse: off [fixed] rx-vlan-filter: on [fixed] vlan-challenged: off [fixed] tx-generic-segmentation: on rx-gro: on rx-lro: off [fixed] tx-tcp-segmentation: on tx-gso-robust: on [fixed] tx-tcp-ecn-segmentation: on tx-tcp-mangleid-segmentation: off tx-tcp6-segmentation: on tx-fcoe-segmentation: off [fixed] tx-gre-segmentation: off [fixed] tx-gre-csum-segmentation: off [fixed] tx-ipxip4-segmentation: off [fixed] tx-ipxip6-segmentation: off [fixed] tx-udp_tnl-segmentation: off [fixed] tx-udp_tnl-csum-segmentation: off [fixed] tx-gso-partial: off [fixed] tx-tunnel-remcsum-segmentation: off [fixed] tx-sctp-segmentation: off [fixed] tx-esp-segmentation: off [fixed] tx-udp-segmentation: off tx-gso-list: off [fixed] tx-checksum-fcoe-crc: off [fixed] tx-checksum-sctp: off [fixed] rx-ntuple-filter: off [fixed] rx-hashing: off [fixed] rx-checksum: on [fixed] tx-nocache-copy: off loopback: off [fixed] rx-fcs: off [fixed] rx-all: off [fixed] tx-vlan-stag-hw-insert: off [fixed] rx-vlan-stag-hw-parse: off [fixed] rx-vlan-stag-filter: off [fixed] l2-fwd-offload: off [fixed] hw-tc-offload: off [fixed] esp-hw-offload: off [fixed] esp-tx-csum-hw-offload: off [fixed] rx-udp_tunnel-port-offload: off [fixed] tls-hw-tx-offload: off [fixed] tls-hw-rx-offload: off [fixed] rx-gro-hw: on tls-hw-record: off [fixed] rx-gro-list: off macsec-hw-offload: off [fixed] rx-udp-gro-forwarding: off hsr-tag-ins-offload: off [fixed] hsr-tag-rm-offload: off [fixed] hsr-fwd-offload: off [fixed] hsr-dup-offload: off [fixed] channels: combined-max: 1 combined: 1 ``` The available features depend on the network card and driver. Some values are fixed by the driver and hardware and cannot be changed. ## Configuration Use the [EthernetConfig](../../reference/configuration/network/ethernetconfig) document to configure Ethernet settings. You can append the machine config document to the machine configuration (separating with `---`), or apply it as a [machine configuration patch](../../configure-your-talos-cluster/system-configuration/patching). For example, to disable TCP segmentation on transmit: ```yaml theme={null} apiVersion: v1alpha1 kind: EthernetConfig name: enp0s2 features: tx-tcp-segmentation: false ``` For rings and channels configuration, values can be increased if they do not exceed the maximum supported by the network card (the maximum values are reported in the status with `-max` suffix). ### Enable Wake-on-LAN support Starting with 1.12, Talos Linux now supports configuring Wake-on-LAN (WOL) directly in the Ethernet configuration. Use the `wakeOnLan` field under the `EthernetConfig` resource to enable WOL and specify the desired WOL modes. This allows a node’s network interface to wake the system from a low-power state when receiving a magic packet or other WOL-triggering event. Example: ```yaml theme={null} apiVersion: v1alpha1 kind: EthernetConfig name: enp0s3 wakeOnLan: enabled: true modes: ["magic", "unicast"] ``` #### Supported modes Supported WOL modes depend on the NIC and driver, but common values include: * `"magic"` — wake on magic packet (most common) * `"unicast"` — wake on unicast packets * `"multicast"` — wake on multicast packets * `"broadcast"` — wake on broadcast packets * `"phy"` — wake on PHY activity > **Note**: If no modes are specified and `enabled: true`, Talos defaults to using the "magic" mode when supported by the hardware. > > WOL functionality requires that your hardware and BIOS/UEFI firmware support it and that it is not disabled there. You can check WOL support and status with: ```bash theme={null} talosctl get ethernetstatus -o yaml ``` This command will show the current wakeOnLan settings along with other Ethernet features.
