Field Descri
p
tion
Destination MAC address
MAC address to which the LLDPDU is advertised. To distinguish between LLDP
packets sent and received by different agent types on the same interface, LLDP
specifies different multicast MAC addresses as destination MAC addresses for
LLDP packets to different agent types. It is fixed to multicast MAC address
0x0180-C200-000E (only for LLDP packets destined for the nearest bridge
neighbor), 0x0180-C200-0000 (only for LLDP packets destined for the nearest
customer bridge neighbor), or 0x0180-C200-0003 (only for LLDP packets
destined for the nearest non-TPMR bridge neighbor).
Source MAC address MAC address of the sending port.
Type Ethernet type for the upper layer protocol. It is 0x88CC for LLDP.
Data LLDPDU.
FCS
Frame check sequence, a 32-bit CRC value used to determine the validity of
the received Ethernet frame.
