committed/saved
software
configuration
The configuration stored in the system for a particular node. The RP loads the committed configuration
into memory at startup.
composite directory
The directory for a composite PIE file used to manage all the corresponding packages as a group. See
also PIE.
configuration
register
In Cisco routers, a 16-bit, user-configurable value that determines how the router functions during
initialization. The configuration register can be stored in hardware or software. In hardware, the bit
position is set using a jumper. In software, the bit position is set by specifying a hexadecimal value
using configuration commands. A hexadecimal or decimal value that represents the 16-bit
configuration register value that you want to use the next time the router is restarted. The value range
is from 0x0 to 0xFFFF (0 to 65535 in decimal).
control plane
The control plane oversees the operation of the data plane, allocating resources, providing information,
and handling errors to allow data plane operations to be continuous and efficient.
CORBA
Common Object Request Broker Architecture. Specification that provides the standard interface
definition between OMG-compliant objects. CORBA allows applications to communicate with one
another no matter where they are located or who has designed them.
CoS
class of service. An indication of how an upper-layer protocol requires a lower-layer protocol to treat
its messages. In SNA subarea routing, CoS definitions are used by subarea nodes to determine the
optimal route to establish a given session. A CoS definition comprises a virtual route number and a
transmission priority field. Repetitive, regularly timed signals are used to control synchronous
processes.
CSNP
complete sequence number protocol data unit (PDU). PDU sent by the designated router in an OSPF
network to maintain database synchronization.
CWI
Craft Works Interface. Graphical user interface (GUI) used to configure and operates a Cisco CRS-1
Series routing system. The CWI client runs in a web browser.
D
DCC
data communication channel. Channel that carries provisioning and maintenance data or information
between network elements in the SONET overhead.
DC PEM
DC power entry module.
DDTS
distributed defect tracking system. A method to track software errors and resolutions.
DHCP
Dynamic Host Configuration Protocol. Provides a mechanism for allocating IP addresses dynamically
so that addresses can be reused when hosts no longer need them.
DIMM
dual in-line memory module. Small circuit boards carrying memory integrated circuits, with signal and
power pins on both sides of the board, in contrast to single-in-line memory modules (SIMMs).
DNS
Domain Name System. Mechanism used in the Internet and on private intranets for translating names
of host computers into addresses. The DNS also allows host computers not directly on the Internet to
have a registered name in the same style.
