Object Description

Enable
Globally enable or disable LLDP function

LLDP PDU Disable
Action
Set LLDP PDU disable action: include “Filtering”, “Bridging” and “Flooding”.

Filtering
: discrad all LLDP PDU.

Bridging
: transmit LLDP PDU in the same VLAN.

Flooding
: transmit LLDP PDU for all port.

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
Transmission Interval
value. Valid values are
restricted to 5 - 32768 seconds.
Default:
30
seconds
This attribute must comply with the following rule:
(Transmission 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
Holdtime
multiplied by
Transmission 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 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 - 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 the
value of
Transmit Delay
seconds.
Transmit Delay
cannot be larger than 1/4
of the
Transmission Interval
value. Valid values are restricted to 1 - 8192
seconds.
This attribute must comply with the rule:
