Object Description
 Enable Globally enable or disable LLDP function
 LLDP PDU Disable
Action
Set LLDP PDU disable action: include “Filtering”, “Bridging” and “Flooding”.

Filtering : discrad all LLDP PDU.

Bridging : transmit LLDP PDU in the same VLAN.

Flooding : transmit LLDP PDU for all port.
 Transmission Interval The 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 Transmission Interval value. Valid values are
restricted to 5 - 32768 seconds.
Default: 30 seconds
This attribute must comply with the following rule:
(Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission
Interval >= (4 * Delay Interval)
 Holdtime Multiplier Each LLDP frame contains information about how long the information in the
LLDP frame shall be considered valid. The LLDP information valid period is set
to Holdtime multiplied by Transmission Interval seconds. Valid values are
restricted to 2 - 10 times.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
Therefore, the default TTL is 4*30 = 120 seconds.
 Reinitialization Delay When a port is disabled, LLDP is disabled or the switch is rebooted a LLDP
shutdown frame is transmitted to the neighboring units, signaling that the LLDP
information isn't valid anymore. Tx Reinit controls the amount of seconds
between the shutdown frame and a new LLDP initialization. Valid values are
restricted to 1 - 10 seconds.
 Transmit Delay If some configuration is changed (e.g. the IP address) a new LLDP frame is
transmitted, but the time between the LLDP frames will always be at least the
value of Transmit Delay seconds. Transmit Delay cannot be larger than 1/4
of the Transmission Interval value. Valid values are restricted to 1 - 8192
seconds.
