Windows Lldp Driver

Feb 03, 2018 Microsoft LLDP Protocol Driver: The Link Layer Discovery Protocol (LLDP) is a link layer protocol used by network devices for advertising their identity, capabilities and neighbors on an IEEE 802 local area network. Link-Layer Topology Discovery: The Link-Layer Topology Discovery service is a kernel mode driver. First try to download the latest network driver from the manufacture website and then try to install the driver in Program Compatibility mode. Check if it helps. I would suggest you to run the Program Compatibility troubleshooter and try to install the driver. Check if it helps. Link Discovery (LLDP) is used to discover the far end switch or equipment connected. LLDP is useful when connecting remotely to a lab or in other cases when the topology is not known. I came across this problem using Windows servers 2012 and Mellanox ConnectX-3 Adapter cards, and found the LDWin tool.

What is LLDP?

LLDP (Link Layer Discovery Protocol) is a vendor independent IEEE standard method of advertising information about a device through a network connection to another device. It can assist in determining network topology. The LLDP information is sent from device interfaces at a fixed interval and when received by a switch, the LLDP data is recorded by the switch. The data can consist of as little as the sending interface MAC address (Windows 10/8.x) to details about the system name, description, IP address and capabilities.
The LLDP information presented by the Switch Port Mapper
When the LLDP column is visible, the LLDP cells show information from the device directly connected to the port (if LLDP is received by the switch). This may include the sender's MAC address, IP address, port name, capabilities, port description and system name. Any information not sent is marked 'not advertised'. If no LLDP is recorded for that port by the switch, you will see N/A in the cell.

How does LLDP relate to Network Topology?

LLDP can help identify the device physically connected to the switch port. By carefully examining the LLDP information the switch receives, you can build a network topology map. It is important that as many devices as possible have LLDP enabled and your switch also have LLDP enabled. LLDP is enabled by default in Windows 10 and 8.x, however, LLDP is not always enabled. Most devices like switches, routers, VOIP phones have LLDP capabilities. You may need to turn LLDP on in the device settings and most importantly in the switch.
When does having LLDP information matter?
Any time there is more than one MAC address appearing attached to a switch port LLDP can help you decide which MAC address is the actual attached device.
Example scenarios where multiple MAC addresses will appear:
Switch attached to another switch.
Switch attached to a server running virtual machines.

How to turn on LLDP in the switch

In order to report LLDP packets received from devices attached switch ports, you will need to enable LLDP in the switch. Often this is done from the switch web interface - be sure to write/save any changes you make. But it also may be done from the CLI.
Cisco Switches running IOS - add this to your running-config:
Switch>enable
Switch#show running-config include lldp (use this to verify there are no lldp entries)
Switch#config term
Switch(config)#lldp run
Switch(config)#Ctrl-z
Switch#copy running-config startup-config (this copies the current running configuration so that when it's rebooted it comes back)
HP/HPE Switches - LLDP is enabled globally by default. If it is not enabled, this command starts it globally. 'lldp enable' can be used to control operation on a per-port basis.
HP Switch(config)# lldp run
Dell Force10 Switches - add this to your running-config and save it to your startup-config.
#protocol lldp
#advertise management-tlv system-capabilities
#no disable.

Free, open source LLDP service for Windows

Many versions of Windows do not natively transmitt LLDP packets making it hard to discover them but there is a free simple solution.WinLLDPService installs with minimal effort on Windows and sends LLDP packets. It does require WinPcap to transmit the LLDP packets. If you have Wireshark or NetScanTools Pro installed, you already have WinPcap installed. We use this LLDP software on a Windows Server 2012 machine.
You can download WinLLDPService here. Operational note: if you are using VirtualBox or similar and you start a new VM, you may need to restart the WinLLDPService service.

Microsoft Link-Layer Discovery Protocol (MsLldp) Service Defaults in Windows 10

Microsoft Link-Layer Discovery Protocol Driver.

Default Settings

Startup type:Automatic
Display name:Microsoft Link-Layer Discovery Protocol
Service name:MsLldp
Service type:kernel
Error control:normal
Group:NDIS
Path:%SystemRoot%system32driversmslldp.sys
Registry key:HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMsLldp

Default Behavior

Microsoft Link-Layer Discovery Protocol is a kernel device driver. In Windows 10 it is starting automatically when the operating system starts. If Microsoft Link-Layer Discovery Protocol fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the MsLldp service has failed to start due to the error.

Restore Default Startup Configuration for Microsoft Link-Layer Discovery Protocol

1. Run the Command Prompt as an administrator.

sc config MsLldp start= auto
sc start MsLldp

3. Close the command window and restart the computer.

Windows Lldp Client

The MsLldp service is using the mslldp.sys file that is located in the %WinDir%system32drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
