GS110TPV3
Hello, if I turn off port (for example) g8 (gs110tpv3) in the PoE power configuration section, will the device connected to that port still negotiate (detect) the type of power? I had a situation whe...

The classic resistor and voltage based detection and signature signature PoE negotiation is limited to the physical link, so the cable between the AP and the inector.
An LLDP Power via MDI TLV IEEE 802.3-2015 could go through, however in my understanding of LLDP it should not, neither does a switch forward any further.
Disabling PoE on the port does disable the PoE controller so no negotiation of any kind should never happen.
What means acting strange? Something to talk with the AP manufacturer please.

* But when I connect the DATA port to the NETGEAR switch, the device starts acting strange.
So, when I connect the AP to a PoE injector and to a port on the GS110TP switch, which has PoE power turned off on that specific port, the AP logs say that the power source does not provide enough energy (less than 17 watts), so the AP does not start all services (radio). However, when I bypass the GS110TP switch and use a switch without PoE, the AP starts up fully, and there are no errors in the logs. So, I won't ask the AP supplier, but I'm asking here, because it has to do with the GS110TPv3. Why does the AP communicate about power with the switch, even though the switch has PoE power turned off on that port?
Should the LLDP protocol take into account the disabled PoE support on this port and not communicate power information?

I expect with a PoE port disabled on a port that no PoE handshake is done, neither the classification signals, nor the LLDP using MDI TLV.
Have a different port connected than the one with PoE disabled, or are we facing a firmware issue here? In that case it's a job for Netgear support.

Sprawdzałem kilka razy, punkt dostępowy jest podłączony do portu PoE, który ma wyłączone zasilanie PoE. Jednak komunikacja negocjacji zasilania z urządzeniem AP nadal ma miejsce
