Hold Multiplier
Enter the hold multiplier value.
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.
Reinitialization
Delay
Enter the re-initialization delay value.
When a port is disabled, LLDP is disabled or the switch is rebooted, an LLDP shutdown frame is
transmitted to the neighboring units, signaling that the LLDP information is not 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.
Transmit Delay
Enter the transmission delay value.
If some configuration is changed (for example, 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.
LLDP-MED Fast
Start Repeat
Count
Enter the LLDP-MED fast start repeat count value.
Because there is a risk of an LLDP frame being lost during transmission between neighbors, it is
recommended to repeat the fast start transmission multiple times to increase the possibility of
the neighbors receiving the LLDP frame. With Fast start repeat count it is possible to specify the
number of times the fast start transmission would be repeated. The recommended value is 4
times, given that 4 LLDP frames with a 1 second interval will be transmitted, when an LLDP frame
with new information is received.
