Description
LLDP Parameters
Tx Interval
The switch periodically transmits LLDP frames to its
neighbours 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 to
32768 seconds.
Tx Hold
Each LLDP frame contains information about how long the
information in the LLDP frame will be considered valid. The
LLDP information valid period is set to Tx Hold multiplied by
Tx Interval seconds. Valid values are restricted to 2 to 10 times.
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 to 8192 seconds.
Tx Reinit
When a port is disabled, LLDP is disabled or the switch is
rebooted, an LLDP shutdown frame is transmitted to the
neighbouring units, signalling 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 to 10 seconds.

The switch port number of the logical LLDP port.
