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 switch, as reflected by the page header.
Object Description
• Port
The switch port number of the logical LLDP port.
• Mode
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.
