IPMC is an acronym for IP MultiCast.
IP Source Guard
IP Source Guard is a secure feature used to restrict IP traffic on DHCP snooping untrusted ports by filtering traffic based on
the DHCP Snooping Table or manually configured IP Source Bindings. It helps prevent IP spoofing attacks when a host
tries to spoof and use the IP address of another host.

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.
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 extendsion of IEEE 802.1ab and is defined by the telecommunication industry association (TIA-1057).
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
M
MAC Table
Switching of frames is based upon the DMAC address contained in the frame. The switch builds up a table that maps MAC
addresses to switch ports for knowing which ports the frames should go to ( based upon the DMAC address in the frame ).
This table contains both static and dynamic entries. The static entries are configured by the network administrator if the
