MD5
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.
MIB
Management Information Base. An acronym for Management Information Base. It is a set of
database objects that contains information about a specific device.
MSTP
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.
MRD
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.
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.
MVR
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.
NTP
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.
OAM
Operation, Administration, and Maintenance provides remote management tools
required to monitor and maintain the links to subscriber CPEs (Customer Premise
Equipment). This section describes functions including enabling OAM for selected
ports, loopback testing, and displaying remote device information.
Out-of-Band
Management
Management of the network from a station not attached to the network.
