Examining help in the switch CLI

Examining help in the switch CLI 

Context Sensitive Help
Console Error Messages
Command History Buffer
Provides a list of commands and the arguments associated with a specific command.
Identifies problems with any switch commands that are incorrectly entered so that the operator can alter or correct them.
Allows recall of long or complex commands or entries for reentry, review, or correction.

6.1.5 This page will explain how the help system is used in the CLI of Cisco switches.
The CLI for Cisco switches is very similar to the CLI for Cisco routers.
To use the help system enter a question mark (?). When this sign is entered at the system prompt, a list of commands available for the current command mode is displayed. 
The help system is very flexible. To obtain a list of commands that begin with a particular character sequence, enter those characters followed immediately by the question mark (?). Do not enter a space before the question mark. This form of help is called word help, because it completes a word.
To list keywords or arguments that are associated with a particular command, enter one or more words associated with the command, followed by a space and then a question mark (?). This form of help is called command syntax help, because it provides applicable keywords or arguments based on a partial command.
The Interactive Media Activity will help students understand how switches reduce the size of collision domains.

The next page will discuss switch command modes.

OSI layers / Peer-to-peer communications / TCP/IP model

OSI layers 2.3.4 This page discusses the seven layers of the OSI model. The OSI reference model is a framework that is used to understand how information travels throughout a network. The OSI reference model explains how packets travel through the various layers to another device on a network, even if the sender and destination have different types of network media. In the OSI reference model, there are seven numbered layers, each of which illustrates a particular network function. - Dividing the network into seven layers provides the following advantages: • It breaks network communication into smaller, more manageable parts. • It standardizes network components to allow multiple vendor development and support. • It allows different types of network hardware and software to communicate with each other. • It prevents changes in one layer from affecting other layers. • It divides network communication into smaller parts to make learning it easier to understand. In the foll...

Advantages and disadvantages of link-state routing

Advantages and disadvantages of link-state routing 2.1.5  This page lists the advantages and disadvantages of link-state routing protocols. The following are advantages of link-state routing protocols:  Link-state protocols use cost metrics to choose paths through the network. The cost metric reflects the capacity of the links on those paths. Link-state protocols use triggered updates and LSA floods to immediately report changes in the network topology to all routers in the network. This leads to fast convergence times. Each router has a complete and synchronized picture of the network. Therefore, it is very difficult for routing loops to occur. Routers use the latest information to make the best routing decisions. The link-state database sizes can be minimized with careful network design. This leads to smaller Dijkstra calculations and faster convergence. Every router, at the very least, maps the topology of it...

PC Basic...

• Backplane – A backplane is an electronic circuit board containing circuitry and sockets into which additional electronic devices on other circuit boards or cards can be plugged; in a computer, generally synonymous with or part of the motherboard. • Network interface card (NIC) – An expansion board inserted into a computer so that the computer can be connected to a network. • Video card – A board that plugs into a PC to give it display capabilities. • Audio card – An expansion board that enables a computer to manipulate and output sounds. • Parallel port – An interface capable of transferring more than one bit simultaneously that is used to connect external devices such as printers. • Serial port – An interface that can be used for serial communication in which only one bit is transmitted at a time. • Mouse port – A port used to connect a mouse to a PC. • USB port – A Universal Serial Bus connector. A USB port connects devices such as a mouse or printer to the computer ...
