D-Link DES-1228P user manual Configuration LLDP

Selection options for the Source Ports are as follows:

TX (transmit) mode: Duplicates the data transmitted from the source port and forwards it to the Target Port.

RX (receive) mode: Duplicates the data that gets sent to the source and forwards it to the Target Port.

Both (transmit and receive) mode: Duplicate both the data transmitted from and data sent to the source port, and forwards all the data to the assigned Target Port.

None: Turns off the mirroring of the port.

LLDP (Link Layer Discovery Protocol) provides a IEEE 802.1AB standards-based method for switches to advertise themselves to neighbor devices and to learn about neighbor LLDP devices as well. DES-1228P will keep those information in the Management Information Base (MIB), SNMP utilities can learn the network topology by get the MIB information in each LLDP device. By default, the LLDP function is disabled.
