SAN Switch 2/8V, 2/16V and 2/16N Installation Guide
K
K28.5
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.
kernel flash
Flash (temporary) memory connected to the peripheral bus of the processor, and
visible within the processor's memory space. Also known as “user flash”.
L
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 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.
latency
The period of 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
As applies to fibre channel, a physical connection between two ports, consisting
of both transmit and receive fibres.
link services
A protocol for link-related actions.
LIP
Loop initialization primitive. The signal used to begin initialization in a loop.
Indicates either loop failure or resetting of a node.
LM_TOV
Loop master time-out value. The minimum time that the loop master waits for a
loop initialization sequence to return.
