2 Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide
FL_Port
The FL_Port is the fabric access port used
to connect NL_Ports to the switch in a
loop configuration.
F_Port
The F_Port is the fabric access port used
to connect an N_Port.
FSPF
Fibre-Channel shortest path first.
G_Port
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.
Interswitch Link (ISL)
ISL is a fiber link between two switches.
Loop
A loop is a configuration of devices (for
example, JBODs) connected to the fabric
via an FL_Port interface card.
Multicast
Multicast is used when multiple copies of
data are to be sent to designated multiple
destinations.
N_Port
The N_Port is the designation of an equip-
ment port connected to the fabric.
NL_Port
The NL_Port is the designation of an
equipment port connected to the fabric in
a loop configuration via an FL_Port.
Power-on self-test (POST)
The POST is a series of self-tests which
run each time the unit is booted or reset.
Resource Allocation Time Out Value
(R_A_TOV)
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.
Isolated E_Port
ISL is online but not operational between
switches because of overlapping domain
ID or nonidentical parameters such as
E_O_TOVs.
Simple Network Management
Protocol (SNMP)
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.
SNMPv1
The original standard for SNMP is now re-
ferred to as SNMPv1.
Trap (SNMP)
A trap is a mechanism for SNMP agents
to notify the SNMP management station
of significant events.
Unicast
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.
U_Port
A U_Port has not assumed a specific func-
tion. It is a generic port that can operate
either as an E_Port, an F_Port, or an
FL_Port. For example, a port that is not
connected or has not assumed a specific
function in the fabric is designated as a
U_Port.
Worldwide Name (WWN)
A WWN uniquely identifies a switch on
local and global networks.
