loop initialization
The logical procedure used by an L_Port to discover its environment. Can be used to assign AL_PA addresses, detect
loop failure, or reset a node.
looplet
A set of devices connected in a loop to a port that is a member of another loop.
LR
Link reset. A primitive sequence used during link initialization between two N_Ports in point-to-point topology or an
N_Port and an F_Port in fabric topology. The expected response is an LRR.
LRR
Link reset response. A primitive sequence during link initialization between two N_Ports in point-to-point topology or
an N_Port and an F_Port in fabric topology. It is sent in response to an LR and expects a response of Idle.
MALLOC
Memory allocation. Usually applied to buffer credits.
MBps
Megabytes per second.
Mbps
Megabits per second.
metric
A relative value assigned to a route to aid in calculating the shortest path (1000 at 1 Gbps, 500 at 2 Gbps.
MIB
Management Information Base. An SNMP structure to help with device management, providing configuration and
device information.
MRK
Mark primitive signal. Used only in arbitrated loop, MRK is transmitted by an L_Port for synchronization and is
vendor specific.
MS
Management Server. Software that allows a storage area network (SAN) management application to retrieve
information and administer the fabric and interconnected elements, such as switches, servers, and storage devices.
The MS is located at the Fibre Channel well-known address
FFFFFAh
.
multicast
The transmission of data from a single source to multiple specified N_Ports (as opposed to all the ports on the
N_Port
Node port. A port on a node that can connect to a Fibre Channel port or to another N_Port in a point-to-point
connection. See also
