Autonegotiation allows two devices, such as switches or network interface cards, to automatically exchange information about their capabilities and configure the best possible connection settings, like speed and duplex mode. This enables devices to establish a link with optimal settings for both. Without it, this needs to be done manually

Not PoE+ so no autonegotiation
Yeah I already knew what autonego is, but this bit I didn’t understand, why POE/POE+ would affect auto nego ?

If I had to guess, negotiating POE voltage. Some stuff uses nonstandard voltage like some older ubiquiti gear

Auto negotiation is not an L2 process. It is a physical layer process that is performed before a CDP or LLDP packet can be transmitted.
