(OP)
Hello,
I have a question: does anybody know if the IP address of the IED "sender" is available in the GOOSE data stream?
In 99% of the cases, the network analyzer (Ethereal) does not show the IP address of the IED sender, it only shows the MAC address of its ethernet port. BUT sometimes, Ethereal shows the IP address. Where is this information coming from? Is it added by the switch? Or is it available in the frame?
The IP address is actually very helpful in understanding WHICH IED is the sender, but very often this is not available..
Has anybody experience on that?
Thanks for any input

the IP address is not part of the GOOSE message. It must be the network analyzer that sends some IP level message to the IED and asks for "who has this MAC address?" and the IED answers. After that, the network analyzer replaces the MAC address of the IED with its IP address.
But I am not sure if this is done by the network analyzer or by windows itself. Sometimes it happens, but very often it doesn't happen, and we only get the MAC addresses of the IEDs (as source).
