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 equipment 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 management information base and a management client residing on a network. Since SNMP does not rely on the underlying communication protocols, it can be made available over other protocols, such as UDP/IP. SNMPv1 The original standard for SNMP is now referred 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 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. U_Port A U_Port has not assumed a specific function. 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. 2 Dell PowerVault 51F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

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.
