LLDP Forward Message
Whether to forward the received LLDP packets.
Transmission Interval
Configure the sending period of LLDP notice, the range of
the value is 5 ~ 32,768 seconds, the default is 30 seconds.
This value must follow the following principles:
Send period> = (4 * delay period).
To Maintain The Value Of
Information
Transmission
Equipment
According to the following formula to configure the
lifetime of LLDP (TTL) that sending out notice, values
range from 2 to10, default is 4.
Life time is the agent which receives LLDP to decide how
long to maintain the LLDP information before receiving
the LLDP updates.
TTL in seconds based on the following principles:
The default is TTL 4 * 30 = 120 seconds.
Re-enable The Delay Value
Configure the delay time from the LLDP interface
disconnected to shut down or before re-initialize the link,
the value range is 1 ~ 10 seconds, the default is 2 seconds.
When a LLDP interface is re-initializing, the remote system
LLDP MIB associated with this interface will be deleted.
Transmission Delay
Configure the interval between the continuous sending
notices, which is caused by the change of LLDP MIB
variables, the value range is 1~ 8192 seconds, default is 2
seconds.
Transmission interval is to prevent the local LLDP MIB
objects rapidly change and continuously send LLDP in a
short time. LLDP is possible to send in a multiple rather
than an LLDP MIB object changes.
This attribute must follow the following principles:
(4 * send delay time) <= sending period
Notification Interval
This is the interval between two notifications successfully
triggered by LLDP change. The time is range from 5~3600
seconds. Default is 5 seconds.
