LACP
LACP is an IEEE 802.3ad standard protocol. The Link Aggregation Control Protocol, allows bundling several
physical ports together to form a single logical port.
LLC
The IEEE 802.2 Logical Link Control (LLC) protocol provides a link mechanism for upper layer protocols. It is
the upper sub-layer of the Data Link Layer and provides multiplexing mechanisms that make it possible for
several network protocols (IP, IPX) to coexist within a multi-point network. LLC header consists of 1 byte
DSAP (Destination Service Access Point), 1 byte SSAP (Source Service Access Point), 1 or 2 bytes Control field
followed by LLC information.
LLDP
LLDP is an IEEE 802.1ab standard protocol.
The Link Layer Discovery Protocol (LLDP) specified in this standard allows stations attached to an IEEE 802
LAN to advertise, to other stations attached to the same IEEE 802 LAN, the major capabilities provided by
the system incorporating that station, the management address or addresses of the entity or entities that
provide management of those capabilities, and the identification of the stations point of attachment to the
IEEE 802 LAN required by those management entity or entities. The information distributed via this protocol
is stored by its recipients in a standard Management Information Base (MIB), making it possible for the
information to be accessed by a Network Management System (NMS) using a management protocol such as
the Simple Network Management Protocol (SNMP).
LLDP-MED
LLDP-MED is an extension of IEEE 802.1ab and is defined by the telecommunication industry association
(TIA-1057).
LLQI
LLQI (Last Listener Query Interval) is the maximum response time used to calculate the Maximum Response
Code inserted into Specific Queries. It is used to detect the departure of the last listener for a multicast
address or source. In IGMP, this term is called LMQI (Last Member Query Interval).
LOC
LOC is an acronym for Loss Of Connectivity and is detected by a MEP and is indicating lost connectivity in
the network. Can be used as a switch criteria by EPS
