The F_Port is the Fabric access port used
to connect an N_Port.
The FL_Port is the fabric access port used
to connect NL_Ports to the switch in a
loop configuration.
Fibre-Channel shortest path first.
A port is designated as a G_Port when it
has not assumed a specific function. A
G_Port is a generic switch port that can
operate either as an E_Port or an F_Port.
A port is defined as a G_Port, for example,
when it is not connected or has not yet
assumed a specific function in the fabric.
Hardware that connects incompatible
networks by providing the necessary
translation, both for hardware and
software.
ISL is a fiber link between two switches
ISL is online but not operational between
switches because of overlapping domain
ID or nonidentical parameters such as
E_D_TOVs.
A loop is a configuration of devices (for
example, JBODs) connected to the fabric
via and FL_Port interface card.
Multicast is used when multiple copies of
data are to be sent to designated multiple
destinations.
The N_Port is the designation of an equip-
ment port connected to the fabric.
The NL_Port is the designation of an
equipment port connected to the fabric in
a loop configuration via an FL_Port.
The POST is a series of self-tests that run
each time the unit is booted or reset.
R_A_TOV is used to time out operations
that depend on the maximum possible
time that a frame could be delayed in a
fabric and still be delivered. The value of
R_A_TOV is adjustable in 1-microsecond
increments over a range from 10 to 120
seconds.
SNMP is a TCP/IP protocol that generally
uses the User Datagram Protocol (UDP)
to exchange messages between a man-
agement information base and a
management client residing on a network.
Since SNMP does not rely on the under-
lying communication protocols, it can be
made available over other protocols, such
as UDP/IP.
The original standard for SNMP is now re-
ferred to as SNMPv1.
A trap is a mechanism for SNMP agents
to notify the SNMP management station
of significant events.
Unicast routing provides one or more op-
timal path(s) between any of two
switches that make up the fabric. This is
for a single copy of the data to be sent to
designated destinations.
Unique numeric identifier for each switch;
assigned by manufacturer.
