Selection options for the Source Ports are as follows:

RX (receive) mode: Duplicates the data that gets sent to the source

transmitted from and data sent to the source port, and forwards all the

Configuration > LLDP
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.
