4.9.10 LLDP
On this page, Link Layer Discovery Protocol (LLDP) is used to discover basic information about neighboring devices on the
local broadcast domain. LLDP is a Layer 2 protocol that uses periodic broadcasts to advertise information about the sending
device. Advertised information is represented in Type Length Value (TLV) format according to the IEEE 802.1ab standard, and
can include details such as device identification, capabilities and configuration settings. LLDP also defines how to store and
maintain information gathered about the neighboring network nodes it discovers.
The LLDP setting configuration includes the LLDP Global Setting, LLDP Port Setting and table 4-9-4 show the items of LLDP
setting functions.

4.9.10.1 LLDP Global Setting
This page allows you to configure the LLDP Global settings for Managed PoE+ Switch as the screen in Figure 4-9-32 appears.
Figure 4-9-32: LLDP Global Settings Configuration Page Screenshot
The page includes the following fields:
Object Description
• LLDP State This column provides configuring enable or disable the LLDP function.
• Tx Interval (5-32768) This column provides configuring Tx Interval settings; the default value is 30
and the available range is 5 to 32678. Unit is second.
The Managed PoE+ Switch is periodically transmitting LLDP frames to its
neighbors for having the network discovery information up-to-date.
The interval between each LLDP frame is determined by the Tx Interval value.
This attribute must comply with the following rule:
(Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission
Interval >= (4 * Delay Interval)
• Tx Hold Multiplier (2-10) This column provides configuring the value for Tx Hold Multiplier; the default
value is 4 minute and the available range is 2 to 10.
Each LLDP frame contains information about how long the information in the
LLDP frame will be considered valid. The LLDP information valid period is set to
Tx Hold multiplied by Tx Interval seconds.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
