related directly to the hardware interface for network devices and passes
on traffic based on MAC addresses.

LLDP 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 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.

WITCHING
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.
