Thank you, this one works.
Actually I was trying to get the links to the hosts, but I realized could
just get it from the mac_to_port lists.
Anyway, I have a different question.
Is it possible to know if 2 different interfaces belong to the same host ?
for example is if this host is connected to a switch through 2 different
interface.
Best regards,
Chandra
