User’s Manual of SGSD-1022 / SGSD-1022P
SGSW-2840 / SGSW-2840P
Default: 30 seconds
This attribute must comply with the following rule:
(Transmission Interval * Hold Time Multiplier) ≤65536, and Transmission Interval
>= (4 * Delay Interval)
• Hold Time Multiplier Configures the time-to-live (TTL) value sent in LLDP advertisements as shown
in the formula below.
Range: 2-10;
Default: 4
The time-to-live tells the receiving LLDP agent how long to retain all information
pertaining to the sending LLDP agent if it does not transmit updates in a timely
manner.
TTL in seconds is based on the following rule:
(Transmission Interval * Holdtime Multiplier) ≤ 65536.
Therefore, the default TTL is 4*30 = 120 seconds.
• Delay Interval Configures a delay between the successive transmission of advertisements
initiated by a change in local LLDP MIB variables.
Range: 1-8192 seconds;
Default: 2 seconds
The transmit delay is used to prevent a series of successive LLDP transmissions
during a short period of rapid changes in local LLDP MIB objects, and to increase
the probability that multiple, rather than single changes, are reported in each
transmission.
This attribute must comply with the rule:
(4 * Delay Interval) ≤Transmission Interval
• Reinitialization Delay Configures the delay before attempting to re-initialize after LLDP ports are
disabled or the link goes down.
Range: 1-10 seconds;
Default: 2 seconds
When LLDP is re-initialized on a port, all information in the remote systems LLDP
MIB associated with this port is deleted.
• Notification Interval Configures the allowed interval for sending SNMP notifications about LLDP MIB
changes.
Range: 5-3600 seconds;
