Policy CSP - ADMX_LinkLayerTopologyDiscovery

  • Article

Tip

This CSP contains ADMX-backed policies which require a special SyncML format to enable or disable. You must specify the data type in the SyncML as <Format>chr</Format>. For details, see Understanding ADMX-backed policies.

The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see CDATA Sections.

This policy setting changes the operational behavior of the Mapper I/O network protocol driver.

LLTDIO allows a computer to discover the topology of a network it's connected to. It also allows a computer to initiate Quality-of-Service requests such as bandwidth estimation and network health analysis.

  • If you enable this policy setting, additional options are available to fine-tune your selection. You may choose the "Allow operation while in domain" option to allow LLTDIO to operate on a network interface that's connected to a managed network. On the other hand, if a network interface is connected to an unmanaged network, you may choose the "Allow operation while in public network" and "Prohibit operation while in private network" options instead.

  • If you disable or don't configure this policy setting, the default behavior of LLTDIO will apply.

This is an ADMX-backed policy and requires SyncML format for configuration. For an example of SyncML format, refer to Enabling a policy.

./Device/Vendor/MSFT/Policy/Config/ADMX_LinkLayerTopologyDiscovery/LLTD_EnableRspndr

This policy setting changes the operational behavior of the Responder network protocol driver.

The Responder allows a computer to participate in Link Layer Topology Discovery requests so that it can be discovered and located on the network. It also allows a computer to participate in Quality-of-Service activities such as bandwidth estimation and network health analysis.

  • If you enable this policy setting, additional options are available to fine-tune your selection. You may choose the "Allow operation while in domain" option to allow the Responder to operate on a network interface that's connected to a managed network. On the other hand, if a network interface is connected to an unmanaged network, you may choose the "Allow operation while in public network" and "Prohibit operation while in private network" options instead.

  • If you disable or don't configure this policy setting, the default behavior for the Responder will apply.
