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.

LLDP-MED (Link Layer Discovery Protocol-Media Endpoint Discovery) is an enhancement of LLDP. It
improves the LLDP operation between endpoint devices such as IP phones and APs. LLDP-MED supports
features such as Auto-discovery of LAN policies and device location discovery. Currently, DGS-1210-28P
supports onlly the extended and automated power management of PoE end points for 802.3at ports (ports
1~4).
This page allows user to configure the Power PSE TLV (Type-length-value) state of 802.3at ports. Select
From Port/ To Port and Enable / Disable and then click Apply to turn on/off the Power PSE TLV
transmission.
