Aging Time
The remote system's LLDP specific information is stored in the LLDP MIB. The TTL TLV carries a posi-
tive value in seconds, and tells the other device as how long this information is valid. Once a remote
device is learned on a local port, if the receiving device doesn't receive an LLDPDU from the same remote
device and on the same local port within the TTL mentioned in the previous LLDPDU, then the local
device discards that entry from its database. This is called the aging time and can be set by the user.
