Link Aggregation
See Port Trunk.
Link Aggregation Control Protocol (LACP)
Allows ports to automatically negotiate a trunked link with LACP-configured ports on
another device.
Link Layer Discovery Protocol (LLDP)
LLDP 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.
Management Information Base (MIB)
An acronym for Management Information Base. It is a set of database objects that
contains information about a specific device.
MD5 Message-Digest Algorithm
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.
Multicast Switching
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
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.
Multiple Spanning Tree Protocol (MSTP)
MSTP 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.
