User Guidelines
The actual Time-To-Live (TTL) value of LLDP frames is calculated by the following
formula:
TTL = min(65535, LLDP-Timer * LLDP-hold-multiplier)
For example, if the value of the LLDP timer is 30 seconds, and the value of the
LLDP hold multiplier is 4, then the value 120 is encoded in the TTL field of the
LLDP header.
