Just a Bunch Of Disks; indicates a number of disks connected in a single chassis to one or more controllers. See also RAID.

A special 10-bit character used to indicate the beginning of a transmission word that performs Fibre Channel control and signaling functions. The first seven bits of the character are the comma pattern. See also Comma.

Loop Port; a node port (NL_Port) or fabric port (FL_Port) that has arbitrated loop capabilities. An L_Port can be in one of two modes:

•Fabric mode Connected to a port that is not loop capable, and using fabric protocol.

•Loop mode In an arbitrated loop and using loop protocol. An L_Port in loop mode can also be in participating mode or non-participating mode.

See also Non-participating Mode, Participating Mode.

The period of time required to transmit a frame, from the time it is sent until it arrives.

As applies to Fibre Channel, a physical connection between two ports, consisting of both transmit and receive fibres. See also Circuit.

A protocol for link-related actions.

Loop Initialization Primitive; the signal used to begin initialization in a loop. Indicates either loop failure or resetting of a node.

Loop Master Time-out Value; the minimum time that the loop master waits for a loop initialization sequence to return.

Loss of signal within a loop for any period of time, or loss of synchronization for longer than the time-out value.

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.

A hex value representing one of the 127 possible AL_PA values in an arbitrated loop.

A set of devices connected in a loop to a port that is a member of another loop.

Loop Port State Machine; the logical entity that performs arbitrated loop protocols and defines the behavior of L_Ports when they require access to an arbitrated loop.

Long Wavelength; a type of fiber optic cabling that is based on 1300mm lasers and supports link speeds of 1.0625 Gbps. May also refer to the type of GBIC or SFP. See also SWL.

As relates to trunking, the port that determines the routing paths for all traffic flowing through the trunking group. One of the ports in the first ISL in the trunking group is designated as the master port for that group. See also ISL Trunking.

Management Information Base; an SNMP structure to help with device management, providing configuration and device information. The MIB types provided with HP Brocade switches are described in the MIB Reference Manual.

The transmission of data from a single source to multiple specified N_Ports (as opposed to all the ports on the network). See also Broadcast, Unicast.
