Glossary
never principal The setting that prevents the product from becoming the principal
switch for a fabric.
next hop gateway
address
The iFCP/iSCSI ports on the SAN Router interact with the external IP
network as if they were independent IP hosts. Each iFCP/iSCSI port
needs a gateway address of an external router that can forward the
storage traffic to the remote iFCP/iSCSI port. This next hop gateway
address is the first-hop gateway address.
NIC See network interface card.
nickname Alternate name assigned to a world-wide name for a node, director
or switch in the fabric.
NL_Port See node loop port.
node In Fibre Channel protocol, an end device (server or storage device)
that is or can be connected to a switched fabric. See also
device.
node loop port NL_Port. A physical interface within an end device (node) that
participates in a loop containing one or more fabric loop ports
(FL_Ports) or other NL_Ports. See also
bridge port; expansion port;
fabric loop port; fabric port; generic port; hub port; node port;
segmented expansion port.
node port N_Port. Physical interface within an end device that can connect to an
fabric port (F_Port) on a switched fabric or directly to another N_Port
(in point-to-point communications). See also
bridge port; expansion
port; fabric loop port; fabric port; generic port; hub port; node loop
port; segmented expansion port.
node port identifier N_Port ID. In Fibre Channel protocol, a unique address identifier by
which an N_Port is uniquely known. It consists of a domain (most
significant byte), an area, and a port, each 1 byte long. The N_Port ID
is used in the source identifier (S_ID) and destination identifier
(D_ID) fields of a Fibre Channel frame.
nondisruptive
maintenance
See concurrent maintenance.
nonvolatile random
access memory
NV-RAM. RAM that retains its content when the device power is
turned off.
N_Port See node port.
