The fields in the frame are described in Table 1-1 :
Table 1-1 Description of the fields in an Ethernet II encapsulated LLDPDU
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.

LLDP.
Data LLDP data.
FCS
Frame check sequence, a 32-bit CRC value used to determine
the validity of the received Ethernet frame.
