Parameter d escription:
LLDP P arameters
Tx I nterval:

The switch periodically transmits LLDP frames to its neighbors to have the network discovery
information up-­‐to-­‐date. The interval between each LLDP frame is determined by the Tx Interval
value. V alid v alues a re r estricted t o 5 –32768 s econds.
Tx H old:

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. V alid v alues a re r estricted t o 2 –10 t imes.
Tx D elay:

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 T x Delay seconds. Tx Delay
cannot b e l arger t han 1 /4 o f t he T x I nterval v alue. V alid v alues a re r estricted t o 1 –8192 s econds.
 Tx R einit:
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 isn't valid anymore. Tx

Rx only: The switch will not send out LLDP information, but LLDP information from neighbor units
is a nalyzed.
Tx only: The switch will drop LLDP information received from neighbors, but will send out LLDP
information.
Disabled: The switch will not send out LLDP information, and will drop LLDP information received
from n eighbors.
Enabled: The switch will send out LLDP information, and will analyze LLDP information received
from n eighbors.
