Reinitialization period (default is two seconds).
Delay between LLDP transmissions (default is two seconds)—applies to triggered updates, or updates that are initiated by a change in the topology.
Transmit interval (default is 30 seconds)—applies to messages sent periodically as part of protocol.
Once the LLDP MED TLVs begin transmitting (after detecting LLDP MED TLVs from a connected endpoint), those TLVs are also controlled by these timers.
When LLDP is disabled or if the link goes down, LLDP is reinitialized. The reinitialize delay is the number of seconds the port waits to restart the LLDP state machine; the default is two seconds.
The time between triggered update LLDP messages is referred to as the transmit delay, and the default value is two seconds. You can change the default transmit delay value to a specified number of seconds or to be automatically calculated by multiplying the transmit interval by 0.25.
Each LLDP message contains a TTL value. The receiving LLDP agent discards all LLDP messages that surpass the TTL value; the default value is 120 seconds. The TTL is calculated by multiplying the transmit interval value and the transmit hold value; the default transmit hold value is four.
LLDP messages are transmitted at a set interval; this interval has a default value of every 30 seconds.
