= Example: Node network configuration policy to enable LLDP reporting
The following YAML file is an example of a `NodeNetworkConfigurationPolicy` manifest that enables the Link Layer Discovery Protocol (LLDP) listener for all ethernet ports in your {product-title} cluster. Devices on a local area network can use LLDP to advertise their identity, capabilities, and neighbor information.
[source,yaml]

name: enable-lldp-ethernets-up # <1>

# ...

<1> Specifies the name of the node network configuration policy.
<2> Specifies that LLDP is enabled for all ethernet ports that have the interface state set to `up`.
