Link Layer Discovery Protocol is used to discover basic information about
neighboring devices in the local broadcast domain by using periodic
broadcasts to advertise information such as device identification,
capabilities and configuration settings.
MD5 Message-Digest is an algorithm that is used to create digital
signatures. It is intended for use with 32 bit machines and is safer than the
MD4 algorithm, which has been broken. MD5 is a one-way hash function,
meaning that it takes a message and converts it into a fixed string of digits,
also called a message digest.
Management Information Base. An acronym for Management Information
Base. It is a set of database objects that contains information about a
specific device.
Multiple Spanning Tree Protocol can provide an independent spanning tree
for different VLANs. It simplifies network management, provides for even
faster convergence than RSTP by limiting the size of each region, and
prevents VLAN members from being segmented from the rest of the group.
Multicast Router Discovery is a A protocol used by IGMP snooping and
multicast routing devices to discover which interfaces are attached to
multicast routers. This process allows IGMP-enabled devices to determine
where to send multicast source and group membership messages.
A process whereby the switch filters incoming multicast frames for services
for which no attached host has registered, or forwards them to all ports
contained within the designated multicast VLAN group.
Multicast VLAN Registration is a method of using a single network-wide
multicast VLAN to transmit common services, such as such as television
channels or video-on-demand, across a service-provider's network. MVR
simplifies the configuration of multicast services by using a common VLAN
for distribution, while still preserving security and data isolation for
subscribers residing in both the MVR VLAN and other standard or private
VLAN groups.
Network Time Protocol provides the mechanisms to synchronize time
across the network. The time servers operate in a
hierarchical-master-slave configuration in order to synchronize local clocks
within the subnet and to national time standards via wire or radio.
Management of the network from a station not attached to the network.
See IEEE 802.1X.
A method whereby data on a target port is mirrored to a monitor port for
troubleshooting with a logic analyzer or RMON probe. This allows data on
the target port to be studied unobstructively.
Defines a network link aggregation and trunking method which specifies
how to create a single high-speed logical link that combines several
lower-speed physical links.
Private VLANs
Private VLANs provide port-based security and isolation between ports
within the assigned VLAN. Data traffic on downlink ports can only be
forwarded to, and from, uplink ports.
