MIB Management Information Base. MIBs make up a database of information (for
example, traffic statistics and port settings) that the switch makes available to
network management systems. MIB names identify objects that can be
managed in a network and contain information about the objects. MIBs provide a
means to configure a network device and obtain network statistics gathered by
the device. Standard, minimal MIBs have been defined, and vendors often have
private enterprise MIBs.
MIP In CFM, the maintenance intermediate point is intermediate between endpoints.
Each MIP is associated with a single domain, and there may be more than one
MIP in a single domain.
mirroring Port mirroring configures the switch to copy all traffic associated with one or
more ports to a designated monitor port. The monitor port can be connected to
an network analyzer or RMON probe for packet analyzer.
MMF Multimode fiber. MMF is a fiber optic cable with a diameter larger than the optical
wavelength, in which more than one bound mode can propagate. Capable of
sending multiple transmissions simultaneously, MMF is commonly used for
communications of 2 kilometers or less.
MSM Master Switch Fabric Module. This NETGEAR-proprietary name refers to the
module that holds both the control plane and the switch fabric for switches that
run the XCM8800 software on modular switches. One MSM is required for
switch operation; adding an additional MSM increases reliability and throughput.
Each MSM has two CPUs. The MSM has LEDs as well as a console port,
management port, modem port, and compact flash; it may have data ports as
well. The MSM is responsible for upper-layer protocol processing and system
management functions. When you save the switch configuration, it is saved to all
MSMs.
MSDP Multicast Source Discovery Protocol. MSDP is used to connect multiple
multicast routing domains. MSDP advertises multicast sources across Protocol
Independent Multicast-Sparse Mode (PIM-SM) multicast domains or
Rendezvous Points (RPs). In turn, these RPs run MSDP over TCP to discover
multicast sources in other domains.
MSTI Multiple Spanning Tree Instances. MSTIs control the topology inside an MSTP
region. An MSTI is a spanning tree domain that operates within a region and is
bounded by that region; and MSTI does not exchange BPDUs or send
notifications to other regions. You can map multiple VLANs to an MSTI; however,
each VLAN can belong to only one MSTI.You can configure up to 64 MSTIs in
an MSTP region.
MSTI regional root bridge In an MSTP environment, each MSTI independently elects its own root bridge.
The bridge with the lowest bridge ID becomes the MSTI regional root bridge.
The bridge ID includes the bridge priority and the MAC address.
MSTI root port In an MSTP environment, the port on the bridge with the lowest path cost to the
MSTI regional root bridge is the MSTI root port.
