Description
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)
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.
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
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.
Description
The switch port number of the logical LLDP port.
Select LLDP mode.

Rx only The switch will not send out LLDP information, but LLDP information from
neighbor units is analyzed.

Tx only The switch will drop LLDP information received from neighbors, but will send
out LLDP information.

Disabled The switch will not send out LLDP information, and will drop LLDP
information received from neighbors.

Enabled The switch will send out LLDP information, and will analyze LLDP information
