OAM is an acronym for Operation Administration and Maintenance.
It is a protocol described in ITU-T Y.1731 used to implement carrier ethernet functionality.

Optional TLVs.
A LLDP frame contains multiple
For some TLVs it is configurable if the switch shall include the TLV in the LLDP frame. These
TLVs are known as optional TLVs. If an optional TLVs is disabled the corresponding
information is not included in the LLDP frame.
OUI
OUI is the organizationally unique identifier. An OUI address is a globally unique identifier
assigned to a vendor by IEEE. You can determine which vendor a device belongs to according
to the OUI address which forms the first 24 bits of a MAC address.
P
PCP
PCP is an acronym for Priority Code Point. It is a 3-bit field storing the priority level for the
802.1Q frame. It is also known as
PD
PD is an acronym for Powered Device. In a

PHY
PHY is an abbreviation for Physical Interface Transceiver and is the device that implement the
Ethernet physical layer (IEEE-802.3).
PING
PING is a program that sends a series of packets over a network or the Internet to a specific
computer in order to generate a response from that computer. The other computer responds
with an acknowledgment that it received the packets. Ping was created to verify whether a
specific computer on a network or the Internet exists and is connected.
ping uses Internet Control Message Protocol (ICMP) packets. The PING Request is the packet
from the origin computer, and the PING Reply is the packet response from the target.
PoE
PoE is an acronym for Power Over Ethernet.
Power Over Ethernet is used to transmit electrical power, to remote devices over standard
Ethernet cable. It could for example be used for powering IP telephones, wireless LAN access
points and other equipment, where it would be difficult or expensive to connect the equipment
to main power supply.
