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
connectivity in the network. Can be used as a switch criteria by
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
administrator wants to do a fixed mapping between the DMAC address and switch ports.
The frames also contain a MAC address ( SMAC address ), which shows the MAC address of
the equipment sending the frame. The SMAC address is used by the switch to automatically
update the MAC table
the MAC table if no frame with the corresponding SMAC address have been seen after a
configurable age time.
MEP
MEP is an acronym for Maintenance Entity Endpoint and is an endpoint in a Maintenance
Entity Group (ITU-T Y.1731).
MD5
MD5 is an acronym for Message-Digest algorithm 5. MD5 is a message digest algorithm, used
cryptographic hash function with a 128-bit hash value. It was designed by Ron Rivest in 1991.
MD5 is officially defined in RFC 1321 - The MD5 Message-Digest Algorithm.
Mirroring
For debugging network problems or monitoring network traffic, the switch system can be
configured to mirror frames from multiple ports to a mirror port. (In this context, mirroring a
frame is the same as copying the frame.)
Both incoming (source) and outgoing (destination) frames can be mirrored to the mirror port.
MLD
MLD is an acronym for Multicast Listener Discovery for IPv6. MLD is used by IPv6 routers
to discover multicast listeners on a directly attached link, much as IGMP is used in IPv4. The
protocol is embedded in ICMPv6 instead of using a separate protocol.
MSTP
In 2002, the IEEE introduced an evolution of RSTP: the Multiple Spanning Tree Protocol. The
MSTP protocol provides for multiple spanning tree instances, while ensuring RSTP and STP
compatibility. The standard was originally defined by IEEE 802.1s, but was later incorporated
with these dynamic MAC addresses. Dynamic entries are removed from
