LLDP Parameters
•
Tx Interval
- The switch periodically transmits LLDP frames to its neighbors to update the
network discovery information. The interval between the LLDP frames is determined by the
Tx
Interval
value. Valid values are restricted to 5 - 32768 seconds.
•
Tx Hold
- Each LLDP frame contains information that determines 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.
•
Tx Delay
- If a 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.
•
Tx Reinit
- When an interface 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 is
not valid anymore.
Tx Reinit
controls the number of seconds between the shutdown frame and
a new LLDP initialization. Valid values are restricted to 1 - 10 seconds.

LLDP Interface Configuration
•
Interface
- The name of the switch’s logical LLDP interface.
•
Mode
- Select LLDP mode.
o
Rx only:
The switch will not send out LLDP information, but LLDP information from neighbor
units is analyzed.
