This is using Windows 10 Enterprise Build 10586.318 I did run the TCPDUMP above as an administrator.

Oh, BTW, I could get this wonderful tool to work on a Windows 7 Enterprise client with the same network drop, so it isn't anything in the network infrastructure preventing the capture.

Please try with capital "D": tcpdump.exe -D

Oops, should have expected case sensitivity from a Unix app ported to Windows :) I don't get anything from the capture after letting it run for 5 minutes.

It is LLDP that we are using in this case, if that makes any difference.

chall32 commented 8 years ago

Works fine for me under Windows 10:

ldwin-win10

LLDP test info created using https://sourceforge.net/projects/lldpgenerator/ (run under Linux Mint)

I am also unable to get CDP data in Windows 10. This is in the new build however, 1603. The 1511 build was working correctly.

KMC123321 commented 7 years ago

My issue turned out to be the Avaya IP phone interfering with the LLDP data coming from the switch. You might want to make sure you don't have anything between your Ethernet port and the switch or network port other than the cable.
