I have the switch mentioned above as well as a third party switch and a non SDN Tp-link switch, I can see clients on the end of both switches but only after a SDN controller reboot ( controller software is on a windows 10 box)..after a short while the clients disappear, the switches are on the end of powerline adaptors..one set is TP-link the other third party, both have the same issues. The clients get an IP address from my firewall and all work and they all come into the same port on the switch ( both powerline adaptors syncing with a third whose output goes into the switch (TL-SG2428P V1), just cant see them on the SDN controller. Clients directly connected to the switch works, also I have a EAP245 on a powerline adaptor and I can see that on the controller... Any ideas?? Thanks..
