LLDP (Link Layer Discovery Protocol) provides IEEE 802.1AB standards-based method for switches to
advertise themselves to neighbor devices, as well as to learn about neighbor LLDP devices. SNMP utilities
can learn the network topology by obtaining the MIB information in each LLDP device. The LLDP function is
enabled by default.
LLDP: When this function is Enabled, the switch can start to transmit, receive and process the LLDP packets.
For the advertisement of LLDP packets, the switch announces the information to its neighbor through ports.
For the receiving of LLDP packets, the switch will learn the information from the LLDP packets advertised
from the neighbor in the neighbor table. Click Apply to make the change effective.
Message TX Hold Multiplier (2-10): This parameter is a multiplier that determines the actual TTL value
used in an LLDPDU. The default value is 4.
Message TX Interval (5-32768): This parameter indicates the interval at which LLDP frames are transmitted
on behalf of this LLDP agent. The default value is 30 seconds.
LLDP ReInit Delay (1-10): This parameter indicates the amount of delay from the time adminStatus
becomes "disabled" until re-initialization is attempted. The default value is 2 seconds.
LLDP TX Delay (1-8192): This parameter indicates the delay between successive LLDP frame
transmissions initiated by value or status changes in the LLDP local systems MIB. The value for txDelay is
set by the following range formula: 1 < txDelay < (0.25 °— msgTxInterval). The default value is 2 seconds.

By selecting a range of ports (From Port and To Port), the power PSE TLV type can be enabled for all
selected ports to indicate the power source equipment (PSE) switch to transmit high power (15.4 to 30 Watts)
to the pre-standard of 802.3at power devices via LLDP MDI TLV. Through this feature, the PSE can provide
precise output power to the pre-standard of 802.3at power devices and achieve optimal power management.
