The F_Port is the fabric access port used
to connect an N_Port.

serial transceiver module designed to pro-

and other protocols that use the same

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.

ISL is a fiber link between two switches.
A loop is a configuration of devices (for
example, JBODs) connected to the fabric
via an 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 which
run each time the unit is booted or reset.

R_A_TOV (Resource Allocation Time Out
Value) 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.

ISL is online but not operational between
switches because of overlapping domain
ID or nonidentical parameters such as
E_O_TOVs.

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.
Because SNMP does not rely on the un-
derlying 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
optimal 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.

A port is designated as a U_Port when it
has not assumed a specific function. A
U_Port is a generic port that can operate
either as an E_Port, an F_Port, or an
FL_Port. A port is defined as a U_Port, for
example, when it is not connected or has
not yet assumed a specific function in the
fabric.

A WWN uniquely identifies a switch on
local and global networks.
