The Page includes the following fields:
LLDP Parameters
Object Description

Tx 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
Tx 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)

Tx Hold
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
Tx Hold
multiplied by
Tx 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.

Tx 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
Tx Delay
seconds.
Tx Delay
cannot be larger than 1/4 of the
Tx Interval
value. Valid values are restricted to 1 - 8192 seconds.
This attribute must comply with the rule:
(4 * Delay Interval) ≤ Transmission Interval

Tx Reinit
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.
LLDP Port Configuration
The LLDP port settings relate to the currently selected stack unit, as reflected by the Page header.
