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.
