9 LLDP
49
Field
Description
Destination MAC
address
The MAC address to which the LLDPDU is advertised. It is
fixed to 0x0180-C200-000E, a multicast MAC address.
Source MAC address
The MAC address of the sending port. If the port does not
have a MAC address, the MAC address of the sending
bridge is used.
Type
The Ethernet type for the upper layer protocol. It is
0x88CC for LLDP.
Data
LLDP data unit (LLDPDU)
FCS
Frame check sequence, a 32-bit CRC value used to
determine the validity of the received Ethernet frame
(2) SNAP-encapsulated LLDPDU format

When Ethernet II encapsulation format is adopted, LLDPDUs sent from the port with LLDP
enabled will be encapsulated with Ethernet II format, and the device will only deal with the
