Receiving LLDPDUs
An LLDP-enabled port that is operating in TxRx mode or Rx mode checks the validity of TLVs carried in
every received LLDPDU. If valid, the information is saved and an aging timer is set for it based on the time
to live (TTL) value in the Time to Live TLV carried in the LLDPDU. If the TTL value is zero, the information
ages out immediately.
