Dear IWAMOTO, Thanks you very much for your reply. I will share the experience after varying this value. There is another question from me too. Can we apply LLDP packet for software defiend wireless network. That part is really confused to me as I see that LLDP packet is mainly used in wired network and I am also trying to detect the specific link status in between the wireless nodes.
