SNMP
Simple network management protocol.
SNMP is a networking protocol that
enables you to monitor the router using
third-party applications that use SNMP.
storage area network
See SAN.
target
The storage-device endpoint of a SCSI
session. Initiators request data from
targets. Targets are typically disk drives,
tape drives, or other media devices.
Typically a SCSI peripheral device is the
target but an adapter may, in some cases,
be a target. A target can contain many
LUNs.
A target is a device that responds to a
requested by an initiator (the host system).
Peripherals are targets, but for some
commands (for example, a SCSI COPY
command), the peripheral may act as an
initiator.
TCP
Transmission control protocol. A set of
rules to send data in packets over the
Internet protocol.
virtual logical area network
See VLAN.
virtual port group
See VPG.
VLAN
Virtual logical area network (LAN). A group
of hosts with a common set of require-
ments that communicate as if they were
attached to the same wire, regardless of
their physical location. Although a VLAN
has the same attributes as a physical LAN,
it allows for end stations to be grouped
together even if they are not located on the
same LAN segment. VLANs enable
network reconfiguration through software,
instead of physically relocating devices.
VPG
Virtual port group. VPG is the iSR6152
software component used to create
additional logical Fibre Channel adapter
initiator ports on the fabric.

WWN
World wide name. A unique 64-bit identi-
fier assigned to a device by the device
manufacturer.
WWNN
World wide node name. A unique 64-bit
identifier assigned to a device.
WWPN
World wide port name. A unique 64-bit
identifier assigned to each port on a
device. One WWNN may contain multiple
WWPN addresses.
