 <1> To configure the network interface for a newly created node, specify the name of the secret that contains the network configuration. Follow the `nmstate` syntax to define the network configuration for your node. See "Optional: Configuring host network interfaces in the install-config.yaml file" for details on configuring NMState syntax.

 <2> Replace `<num>` for the worker number of the bare metal node in the `name` fields, the `credentialsName` field, and the `preprovisioningNetworkDataName` field.
-+
 <3> Add the NMState YAML syntax to configure the host interfaces.
+<4> Optional: If you have configured the network interface with `nmstate`, and you want to disable an interface, set `state: up` with the IP addresses set to `enabled: false` as shown:
 +
-<4> Replace `<nic1_name>`, `<ip_address>`, `<dns_ip_address>`, `<next_hop_ip_address>` and `<next_hop_nic1_name>` with appropriate values.
-+
-<5> Replace `<base64_of_uid>` and  `<base64_of_pwd>` with the base64 string of the user name and password.
-+
-<6> Replace `<nic1_mac_address>` with the MAC address of the bare metal node's first NIC. See the "BMC addressing" section for additional BMC configuration options.
-+
-<7> Replace `<protocol>` with the BMC protocol, such as IPMI, RedFish, or others. Replace `<bmc_url>` with the URL of the bare metal node's baseboard management controller.
-+
-<8> To skip certificate validation, set `disableCertificateVerification` to true.
-+
-<9> Replace `<bmc_username>` and `<bmc_password>` with the string of the BMC user name and password.
-+
-<10> Optional: Replace `<root_device_hint>` with a device path if you specify a root device hint.
-+
-<11> Optional: If you have configured the network interface for the newly created node, provide the network configuration secret name in the `preprovisioningNetworkDataName` of the BareMetalHost CR.
