MSTP Multiple Spanning Tree Protocol. MSTP, based on IEEE 802.1Q-2003 (formerly
known as IEEE 892.1s), allows you to bundle multiple VLANs into one spanning
tree (STP) topology, which also provides enhanced loop protection and better
scaling. MSTP uses RSTP as the converging algorithm and is compatible with
legacy STP protocols.
MSTP region An MSTP region defines the logical boundary of the network. Interconnected
bridges that have the same MSTP configuration are referred to as an MSTP
region. Each MSTP region has a unique identifier, is bound together by one
CIST that spans the entire network, and contains from 0 to 64 MSTIs. A bridge
participates in only one MSTP region at one time. An MSTP topology is
individual MSTP regions connected either to the rest of the network with 802.1D
and 802.1w bridges or to each other.
MTU Maximum transmission unit. This term is a configurable parameter that
determines the largest packet than can be transmitted by an IP interface (without
the packet needing to be broken down into smaller units).
Note: Packets that are larger than the configured MTU size are
dropped at the ingress port. Or, if configured to do so, the system can
fragment the IPv4 packets and reassemble them at the receiving end.
multicast Multicast messages are transmitted to selected devices that specifically join the
multicast group; the addresses are specified in the destination address field. In
other words, multicast (point-to-multipoint) is a communication pattern in which a
source host sends a message to a group of destination hosts.
multinetting IP multinetting assigns multiple logical IP interfaces on the same circuit or
physical interface. This allows one bridge domain (VLAN) to have multiple IP
networks.
MVR Multicast VLAN registration. MVR allows a subscriber on a port to subscribe and
unsubscribe to a multicast stream on the network-wide multicast VLAN; it allows
the single multicast VLAN to be shared in the network while subscribers remain
in separate VLANs. MVR provides the ability to continuously send multicast
streams in the multicast VLAN, but to isolate the The application from the
subscriber VLANs for bandwidth and security reasons. MVR allows a multicast
stream received over a Layer
2 VLAN to be forwarded to another VLAN,
eliminating the need for a Layer 3 routing protocol; this feature is often used for
IPTV applications.
N
NAT Network Address Translation. This is a network capability that enables a group
of computers to dynamically share a single incoming IP address. NAT takes the
single incoming IP address and creates a new IP address for each client
computer on the network.
