Media Access Control
Moves, Adds, Changes
A Media Access Control address is a 48-bit number, often called the "physical address", "Ethernet address", or "hardware address", used at
the lowest network layer. There are three standard formats used to express MAC-level addresses. For example, 2:60:8c:0:76:67, 02-60-8c-00-76-67,
and 0260.8C00.7667 represent the same MAC-level address.
MacTracker (guest/comet) is a program that tracks Port Lists (SwitchMap) data so that you can
look historical information about MACs, ports, etc. It was written by Robert Bubon of COMET.
Part of an electronic mail delivery system which allows a message to be delivered to a list of addressees. Mail exploders are used to
implement mailing lists. Users send messages to a single address (e.g., firstname.lastname@example.org) and the mail exploder takes care of delivery to the
individual mailboxes in the list.
A machine that connects two or more electronic mail systems (especially dissimilar mail systems on two different networks) and transfers
messages between them. Sometimes the mapping and translation can be quite complex, and generally it requires a store-and-forward scheme whereby
the message is received from one system completely before it is transmitted to the next system after suitable translations.
ADVA's name for their customer website. ADVA pays SalesForce to handle ADVA's online web presence. When you log in to ADVA's website, you get logged in to a
server at SalesForce. ADVA tech support guys are supposed to refer to the ADVA support website as "Max Portal" to
satisfy marketing, but they may refer to it as "Salesforce".
management Ethernet interface on a Juniper switch. If the switch is part of a Virtual Chassis, the me0 interface is disabled and the chassis
is accessed via the vme interface.
Unapproved plug type. This is an alarm that can be reported by ADVA equipment. It means that the the physically inserted plug is not an
approved plug. This can happen because we've inserted an SFP in an R7 shelf that isn't an ADVA-brand SFP, though it may work fine.
Mismatch of plug equipment versus provisioned attributes due to a difference in specifications. This is an alarm that can be reported by ADVA
equipment. It means that the physically inserted plug exceeds the provisioned RATE or REACH settings. Note that in this case, the plug may be
able to provide signal transport, but the specifications of the signal may not conform to the provisioned settings (e.g. the optical power level
may be too high).
Multichassis EtherChannel, a Cisco Layer 2 multipathing technology
Multi-Exit Discriminator, an optional nontransitive BGP attribute that can be attached to an advertised prefix.
The material used to support the transmission of data. Examples include copper wire, coaxial cable, optical fiber, or electromagnetic wave
Merit Network, Inc. maintains a routing registry called the RADb(Routing Assets Database). NETS pays Merit a yearly fee for update access to the

The term MetaCenter refers to the collaboration of national supercomputing centers: CTC, NCSA,
PSC, SDSC, NCAR.

Also known as MAR.
Media Gateway Control Protocol
The management daemon on a Juniper device. mgd manages the configuration of the router and all user commands. The management process is
responsible for notifying other processes when a new configuration is committed. It also spawns a CLI process when a user logs in.
Management Information Base. A collection of objects that can be accessed via a network management protocol like SNMP. NETS stores MIB files
in the /usr/share/snmp/mibs/ directory on netserver, which is where the Net-SNMP command suite (snmpwalk, etc.) looks for MIB files.
Media Interface Connector. The most common connector on the ends of FDDI cables.
Modem ISDN Channel Aggregation
Management Information Format
Mainframe/Internet Gateway Server
MILitary NETwork. Originally part of the ARPANET, MILNET was partitioned in 1984 to make it possible for military installations to have
reliable and secure network service, while the ARPANET continued to be used for research.
Multipurpose Internet Mail Extensions
A small version of an MMAC. It has up to 13 ports, which may be AUI, thin, twisted pair, or fiber.
Millennium Infrastructure Network Technology
Major. An ADVA Notification Code (NC) that indicates that a service affecting condition has developed and an urgent corrective action is
Managed Modem Service, a product sold by Level 3. In 2007, NETS
stopped using a physical RAS device to provide dial-up service to UCAR staff. We bought MMS instead.
Modem Management Technology Licenses (Cisco)
Minor. An ADVA Notification Code (NC) that indicates the existence of a non-service affecting condition and that corrective action should be
taken in order to prevent a more serious (for example, service affecting) fault.
Multiple Registration Protocol, allows bridges, switches or
other similar devices to be able to register and de-register attribute values, such as VLAN identifiers and multicast group membership across
a large LAN.
a Brocade proprietary protocol that prevents Layer 2 loops and provides fast reconvergence in Layer 2 ring topologies. It is an
alternative to STP and is especially useful in Metropolitan Area Networks.
A 10base-T (unshielded twisted pair) hub manufactured by Cabletron Systems. It has 12 ports, with provisions for 2 additional ports that may
be other than 10base-T.
Multi-Source Agreement, an agreement between manufacurers that specifies the properties of the item to allow interaction. MSAs define the
specs for optical transceivers, SFPs, GBICs, CFPs, etc.
Master Services Agreement
Mesa State College, renamed "Colorado Mesa University" in August 2011, was a secondary FRGP member
behind UCDHSC until May 2007, when they elected not to join the new UPoP
A multi-port transceiver manufactured by Cabletron Systems. It has 9 ports, 8 or which are configured to look like a transceiver port. The
9th port connects to a transceiver. This device is basically the same as a DELNI.

A special form of broadcast where copies of the packet are delivered to only a subset of all possible destinations. See MBONE.
The division of a single transmission medium into multiple logical channels supporting many simultaneous sessions. A way to support multiple
connections on one line, often by giving the channel to each session for a short portion of time, then giving another session the channel, then
