Thank you:)

but there is no information about 802.1Q in Specifications

Does it mean that EAP work with 802.1Q? Should it be trunk port between L3 switch and EAP115?

There is TL-R480T+ router in the network (with Port-Based VLAN). Is it possible configure EAP with TL-R480T+ to separate wifi clients and LAN?

Model : Hardware Version : Firmware Version : ISP : How i can create guest access in EAP 115(users should not acecess to LAN )? Is it possible?? SSID isolation does not work.....

After closing EAP controller internal web server works, but now I can not add AP to EAP controller again. The software does not see AP. Does not help reinstalling software and resetting AP.
