cache
A temporary high-speed storage (memory)
area where recently used or frequently
accessed data is stored for rapid access,
thus increasing the efficiency of processor
operations.
CLI
Command line interface. A program inter-
face driven by entering commands and
parameters.

See DCBX.
Data Center Ethernet
See DCE™.
DCB
Data center bridging. Provides enhance-
ments to existing 802.1 bridge specifica-
tions to satisfy the requirements of
protocols and applications in the data
center. Because existing high-perfor-
mance data centers typically comprise
multiple application-specific networks that
run on different link layer technologies
(Fibre Channel for storage and Ethernet
for network management and LAN
connectivity), DCB enables 802.1 bridges
to be used for the deployment of a
converged network where all applications
can be run over a single physical infra-
structure.
DCBX
Data center bridging exchange. A protocol
used by DCB devices to exchange config-
uration information with directly connected
peers. The protocol may also be used for
misconfiguration detection and for configu-
ration of the peer.
DCE™
Data Center Ethernet. Cisco’s foundation
for delivering a unified fabric in which the
end-state network where LAN, SAN, and
inter-process communication (IPC) traffic
are converged onto a single network infra-
structure. The enhancements described
within Cisco Data Center Ethernet helped
create the IEEE 802.1 Data Center
Bridging (DCB) working group.
device
A target, typically a disk drive. Hardware
such as a disk drive, tape drive, printer, or
keyboard that is installed in or connected
to a system. In Fibre Channel, a target
device.
DHCP
Dynamic host configuration protocol.
Enables computers on an IP network to
extract their configuration from servers
that have information about the computer
only after it is requested.
driver
The software that interfaces between the
file system and a physical data storage
device or network media.
dynamic host configuration protocol

embedded switch
See eSwitch.
