The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol
Suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local
area network, principally wired Ethernet.
Description
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: 5 – 32768 seconds
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: 2 – 10 times
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: 1 – 8192 seconds
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. Reinit Delay controls the amount of seconds
between the shutdown frame and a new LLDP initialization.
Valid values: 1 – 10 seconds
Description
Local port number (Port #1: TP port, Port #2: FX port)
Set port LLDP mode:
Disabled:
The switch will not send out LLDP information, and will drop LLDP
information received from neighbors.
Tx and Rx:
The switch will send out LLDP information, and will analyze LLDP
information received from neighbors.
Tx only:
The switch will drop LLDP information received from neighbors, but will
send out LLDP information.
Rx only:
The switch will not send out LLDP information, but LLDP information
from neighbor units is analyzed.
