Hello Simon,
I call the LLDP transmit function lldp_raw(struct netif *netif, const
struct eth_addr *ethsrc_addr) with the MAC address of the port. So if there
are multiple ports each with its MAC address, then that can be resolved by
the 2nd argument of the function.
Also if we put the use restri

that they be different.
No, but if you have more than one port, it's typical to have one MAC per
port. This helps to tell which port of a switch a device is connected to,
for example (e.g. used in

Quoting Fotis Panagiotopoulos :
Look at the wireshark ARP packet:
It should send to the broadcast MAC address (ff:ff:ff:ff:ff:ff)
Look at your send MAC address. This should be valid.
I have seen problems if your MAC address is 0.

Well, it seems I narrowed down the problem.

Hello Sergio, Simon,
I finally got the LLDP basic frame to work. I am able to send the LLDP
frame out of my device and see the same correctly on the wire-shark.
However, do be able to make a proper source code out of it, I would need
advise. The fields of the LLDP are static and not expected to c

OK I bought a managed switch, so I can now monitor the traffic on my
network correctly. I set up the port mirroring function, to forward all
traffic from the ethernet port the uC is connected, to the port that my PC
is connected. I started wireshark but the problems persist.
First my code starts L
Hi, Sylvain.
Thank you for all the follow-up documentation. I definitely agree that using
the *_ANY option allows for downgrade attacks and makes security
weak/non-existent. But that's the trouble with having to support legacy while
also trying to push ahead, isn't it?
