Term Definition
CLI Command Line Interface. A set of line commands used to configure the system.
Client
A computer system or process that requires services or processes for another computer,
typically a server.
CLL
Classification Control Lists. Devices that grant, deny, or limit access to devices, features,
or applications in QoS.
Collision
A overlapping transmission of two or more packets that collide. The data transmitted
cannot be used, and the session is restarted.
Combo Port
A single logical port with two physical connections, including an RJ-45 connection and a
SFP connection.
Community Specifies a group of users which retains the same system access rights.
CPU
Central Processing Unit. The part of a computer that processes information.CPUs are
composed of a control unit and an ALU.
D
Damp
Indicates a state where an interface is not advertising links to the neighboring interface
due to Flapping.
DHCP
Dynamic Host Configuration Protocol. DHCP dynamically assigns IP addresses to devices on
a network. With dynamic addressing, a device can have a different IP address every time it
connects to the network. DHCP also supports a mix of static and dynamic IP addresses.
DHCP Client
An Internet host using DHCP to obtain configuration parameters, such as a network
address.
DHCP Server An Internet host that returns configuration parameters to DHCP clients.
Domain
A group of computers and devices on a network that are grouped with common rules and
procedures.
DSCP
DiffServe Code Point. DSCP provides a method of tagging IP packets with QoS priority
information.
DSL Digital Subscriber Line. Increases the digital capacity of telephone lines.
Duplex Mode
Permits simultaneous transmissions and reception of data. There are two different types
of duplex mode:
• Full Duplex Mode — Permits bisynchronous communication, for example, a telephone.
Two parties can transmit information at the same time.
• Half Duplex Mode — Permits asynchronous communication, for example, a walkie-
talkie. Only one party can transmit information at a time.
DVMRP
Distance Vector Multicast Routing Protocol. DVMRP tunnels multicast messages
within unicast packets. DVMRP supports rate limiting and distribution control based on
destination address.
E
Egress Port
Port from which network traffic is transmitted.
EIGRP
Enhanced Interior Gateway Routing Protocol. Provides fast convergence, support for
variable-length subnet mask, and supports multiple network layer protocols.
End System An end user device on a network.
EPG
Exterior Gateway Protocol. Permits exchanging routing information between two
neighboring gateway hosts in an autonomous systems network.
ESP Encapsulating Security Payload. Provides a variety of security services for IPv4 and IPv6.
