Dell PC2716 Broadcast Storm, Class of Service, Dhcp Client, Domain, Duplex Mode, Egress Ports

Broadcast Storm

An excessive amount of broadcast messages simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, overloading network resources or causing the network to time out.

C

Class of Service

Class of Service (CoS). Class of Service is the 802.1p priority scheme. CoS provides a method for tagging packets with priority information. A CoS value between 0-7 is added to the Layer II header of packets, where zero is the lowest priority and seven is the highest.

D

DHCP Client

An Internet host using DHCP to obtain configuration parameters, such as a network address.

DSCP

DiffServe Code Point (DSCP). DSCP provides a method of tagging IP packets with QoS priority information.

Domain

A group of computers and Ethernet switch modules on a network that are grouped with common rules and procedures.

Duplex Mode

Permits simultaneous transmissions and reception of data. There are two different types of duplex mode:

•Full DuplexMode — Permits for bisynchronous communication, for example, a telephone. Two parties can transmit information at the same time.

•Half DuplexMode — Permits asynchronous communication, for example, a walkie-talkie. Only one party can transmit information at a time.

E

Egress Ports

Ports from which network traffic is transmitted.

End System

An end user Ethernet switch module on a network.

Ethernet

Ethernet is standardized as per IEEE 802.3. Ethernet is the most common implemented LAN standard. Supports data transfer rates of Mpbs, where 10, 100 or 1000 Mbps is supported.
