14.1.3.2 Message Transmit Holdtime Multiplier
The Message Transmit Holdtime Multiplier is used to calculate the time-to-live (TTL) value sent in LLDP
advertisements. The time-to-live informsthe receiving LLDP agent of the timeto retain remote LLDP
informationif LLDP advertisements are not received periodically.
The TTL is calculated as:the minimum of ((Transmission Interval * Holdtime Multiplier), or 65536)
The default holdtime multiplier is 4 seconds. The default TTL is: 4*30 = 120 seconds. Supermicro switches
allow for the user configuration of the message transmit holdtimemultiplier. Follow the steps below to
change the message transmit holdtimemultiplier.
Step
Command
Description
Step 1
configure terminal
Enters the configuration mode
Step 2
lldpholdtime-multiplier <value(2-10)>
(Optional)
Configures the message transmit
holdtimemultiplier, range of 2-10.
Step 3
End
Exits the configuration mode.
Step 4
show lldp
Displays the LLDP global information
The “no lldpholdtime-multiplier” command resets the message transmit
holdtimemultiplierto its default value.
14.1.3.3 ReinitializationDelay
When LLDP ports are disabled or the link goes down, LLDP is reinitialized on a port. The delay between the
port going down and the reinitialization is called the reinitialization delay. When LLDP is reinitialized on a
port, all information in the remote systems LLDP MIB associated with this port is deleted.
Supermicro switches allow user configuration of the reinitialization delay. Follow the steps below to
change the reinitialization delay.

Description
Step 1

Step2
lldpreinitialization-delay <seconds(1-10)>
(Optional)
Configures the reinitialization delay,
range of 1-10.
Step 3
End
Exits the configuration mode.
Step 4
show lldp
Displays the LLDP global information
The “no lldpreinitialization-delay” commandresets the reinitialization delayto its default
value.
