CLI commands - Classes & subnetting of networks

Configuring computer network means that the configuration performs active network equipment in the network, and designed according to the accepted scheme. Sometimes it is used to set the serial RS 232C port on a computer connected with a special connection to the network device. Can be used and different types of connectors, but cable to connect the network devices and computers strictly dedicated supplied with the network device. Via 'Terminal' ('Hyper Terminal' in Windows XP OS) software is possible access to the active network device and giving command contained in the operating system network device is performed to configure. When to a network device is assigned an address that is in line with the creation of a network diagram-firm institutions, can be via a web interface, using a graphical representation of the GUI (Graphic User Interface), configuring a network access device, but not to the full extent as the command line - CLI (Command Line Interface). CLI is the primary way to configure the device.

So firm Cisco in their network devices using IOS (Internetwork Operating System) that allows you to configure the network devices on both these ways. The following provides a little manual that shows how to look at TCP / IP in relation to the OSI network model concept, useful commands for Windows OS contains a snapshot of the set parameters of your computer and control the communication network, a list of computer classes, auxiliary tables for successful subnetting the network, the commands for configuring Cisco routers and switches. Commands allow the network device is defined by the administrator name and its password to configure the communication protocols and a variety of security mechanisms.

 UEM = User Exec Mode                         (view only)
 PEM = Privileged Exec Mode                     (enabled)
 GCM = Global Configuration Mode          (configuration)
-------------- UEM -> PEM -> GCM -> SCM -----------------
 SCM = Specific Configuration Mode

Commands are not the same as described for all types of devices, but according to the approach and its use can be concluded that they belong to the same family unit. Manufacturer periodically for your IOS make improvements that issue once and sometimes offers free of charge, as well as new versions of the operating system, which depends on the content of the agreement entered into when purchasing network equipment. Not good not to secure their support for at least a couple of years.
