LLDP global settings
The LLDP Configuration page allows the user to inspect and configure the current
LLDP port settings.
The page includes the following fields:
Object Description
Enable Globally enable or disable the LLDP function.
LLDP PDU Disable
Action Set the LLDP PDU disable action.
Filtering : discard all LLDP PDU.
Bridging : transmit LLDP PDU in the same VLAN.
Flooding : transmit LLDP PDU for all ports.
Transmission
Interval 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 are
restricted to 5 - 32768 seconds.
Default: 30 seconds
This attribute must comply with the following rule:
(Transmiss
ion Interval * Hold Time Multiplier) ≤65536, and Transmission
Interval >= (4 * Delay Interval)
Holdtime Multiplier 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.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
Therefore, the default TTL is 4*30 = 120 seconds.
Reinitialization Delay 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LLDP information is no longer valid.
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 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
