TP-Link TL-SL3226P - Manual (Page 14)

the IEEE802.1X protocol of Port 2 has been configured to be Enable. Please
note Port Security, Trunk and IEEE802.1X protocol are mutually exclusive.
In other word, when you configure one of them, other two can't be configured.
State
The port can be used when the State is Enable, while the port is prohibited
when the State is Disable. The Switch will discard the packets from the port.
Port Security
When you configure the Port Security of a port to be Enable, the port won't
learn any new MAC address. Furthermore, the port only transfers the Data
Tag accordant to requirements. Other Tags will be discarded. When the Port
Security of a port is Disable, the port will automatically learn any new MAC
address and transfer Tags received.
Flow Control
Disable (default): The port won't produce Flow Control packets and will
discard the Flow Control packets received.
Enabled: The Switch will negotiate Flow Control on the specified port
according to Full-Duplex or Half-Duplex.
Speed/Duplex
10Base-T/100Base-TX ports
Auto (default): auto-test the speed and negotiate the duplex mode with the
other end.

Two independent modules
The operating mode of two independent modules is different according to
different module.
There are four types of the modules:
1) 100M fiber module (such as TL-SM201 series)
Auto: auto-negotiation
100FD: 100Mbps, Full-Duplex
2) 100M Twisted-Pair module (such as TL-SM201U)
Auto: auto-negotiation
10HD: 10Mbps, Half-Duplex
10FD: 10Mbps, Full-Duplex
100HD: 100Mbps, Half-Duplex
100FD: 100Mbps, Full-Duplex
3) Gigabit Fiber Module (such as TL-SM301CS)
Auto: auto-negotiation
1000FD: 1000Mbps, Full-Duplex
4) Gigabit Twisted-Pair module (such as TL-SM301U)
Auto: auto-negotiation
