K28.5 | A special |
| transmission word that performs FC control and signaling |
| functions. The first seven bits are the common pattern. |
kernel flash | Flash (temporary) memory connected to the peripheral bus of |
| the processor and visible within the processor’s memory space. |
| Also called a user flash. |
L_Port | 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 is 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 |

latency | The time required to transmit a frame from the time it is sent |
| until it arrives. Together, latency and bandwidth define the |
| speed and capacity of a link or system. |
link | With respect to FC, a physical connection between two ports, |
| consisting of both transmit and receive fibers. |
link services | A protocol for |
LIP | Loop initialization primitive. The signal that begins initialization |
| in a loop. It indicates either loop failure or the resetting of |
| a node. |
LM_TOV | Loop master |
| master waits for a loop initialization sequence to return. |
loop failure | Loss of signal within a loop for any period of time; loss of |
| synchronization for longer than the |
Loop_ID | A hexadecimal value representing one of the 127 possible |
| AL_PA values in an arbitrated loop. See also AL_PA. |
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. See also AL_PA. |
LPSM | 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. See also L_Port. |
