Q & A

What is the main purpose of using the 'Config' tab in Packet Tracer?

The 'Config' tab in Packet Tracer provides a graphical user interface (GUI) that allows users to configure various aspects of a device, such as global settings, routing, switching, and interfaces, without using the command-line interface (CLI).

What happens when you save the running configuration to NVRAM?

When you save the running configuration to NVRAM, you are saving the current configuration settings (running config) to the device's non-volatile memory (startup config). This ensures that the settings are retained even after a reboot.

How can you configure the IP address on a device using the Config tab?

To configure an IP address in the Config tab, navigate to the 'Interface' section, select the desired interface, and enter the IP address. A default subnet mask will be automatically provided when you click on the subnet mask field.

What can be configured at the 'Global' level in the Config tab?

At the 'Global' level, you can configure settings such as the device's display name, hostname, and perform actions like erasing or saving configurations to NVRAM. You can also import or export configuration files in text format.

What is the equivalent of the 'no shutdown' command in the GUI interface of Packet Tracer?

In the Config tab, turning on the port status for an interface is the equivalent of issuing the 'no shutdown' command in the CLI.

What configuration options are available for a PC in Packet Tracer using the Config tab?

For a PC, the Config tab provides two levels of configuration: 'Global' and 'Interface'. You can configure settings like the display name, IP address (static or DHCP), default gateway, and DNS servers.

Can you use the 'Desktop' tab for routers in Packet Tracer?

No, the 'Desktop' tab is not available for routers in Packet Tracer. It is only available for devices like PCs and servers.

What tools are available in the 'Desktop' tab of a PC in Packet Tracer?

The 'Desktop' tab of a PC in Packet Tracer includes tools like IP Configuration, Command Prompt, Web Browser, Terminal, and Dial-up settings, among others.

What is unique about the 'Services' tab available on a server in Packet Tracer?

The 'Services' tab on a server allows you to manage and provide various services such as HTTP, DHCP, TFTP, and DNS. You can turn these services on or off and adjust their settings as needed.

How does the CLI tab differ between devices in Packet Tracer?

The CLI tab is only available on devices running the IOS operating system, such as routers and switches. It allows users to configure the device using IOS commands, whereas the CLI tab is not available for PCs or servers.

🔧 Introduction to Configuring Devices with the Config Tab

The video introduces the process of configuring devices in Packet Tracer using the 'Config' tab instead of the command-line interface (CLI). It highlights the ease of using the graphical user interface (GUI) for common device configurations, and explains how the Config tab is divided into four levels: global, routing, switching, and interface. The global level allows for basic settings like hostname configuration, erasing or saving configurations, and exporting them as text files. Routing, switching, and interface settings are also briefly mentioned, with an example of setting up an IP address and subnet mask for a device.

💻 Configuring a PC Using the Config Tab

This section discusses how to configure a PC in Packet Tracer using the Config tab, which offers two levels: global and interface. The global settings include display name, interfaces, and gateway configurations, while the interface level allows configuration of IP addresses through static or dynamic (DHCP) methods. An example is provided where a static IP address is configured, and the convenience of automatically generated subnet masks is noted. The section concludes with a mention of how these settings are saved once the window is closed.

🖥️ Using the Desktop Tab on PCs and Servers

The video explains the functionality of the Desktop tab, which is available on PCs but not on routers in Packet Tracer. Through the Desktop tab, users can change the IP configuration, use DHCP or static IPs, and configure default gateways. It also introduces various applications available under this tab, such as Dial-Up, Terminal, and Command Prompt, where users can run commands like 'ipconfig.' The section demonstrates how a web browser can be used to access web pages and notes the differences in applications between PCs and servers.

🛠️ Managing Services on the Server via the Services Tab

In this part, the focus shifts to the Services tab available only on servers in Packet Tracer. The Services tab allows management of server-specific services such as HTTP, DHCP, DNS, and TFTP. The narrator shows how to enable or disable these services and modify their settings. A demonstration follows, where the server acts as an HTTP server, and a webpage is accessed from a PC to confirm the service is functioning properly. This emphasizes the practical use of services within the simulated network environment.

🖧 Configuring Devices via the CLI Tab

This final section covers the use of the CLI (Command Line Interface) tab for devices that run IOS in Packet Tracer, such as routers. The CLI tab allows for manual configuration using IOS commands, as demonstrated by commands like 'enable,' 'config t,' and 'interface gig0/0/0' to configure the interface and assign IP addresses. The narrator explains that while the CLI functions similarly to real devices, users can refer to help files for a full list of commands. The video ends with a note on how to copy and paste commands within the CLI.

Keywords

💡Config Tab

The 'Config Tab' refers to a user interface element in Cisco Packet Tracer that allows users to configure network devices using a graphical user interface (GUI). Instead of relying on command-line input (CLI), users can modify device settings more easily. In the video, it is used to configure devices such as routers and PCs, and allows for modifications like changing IP addresses, MAC addresses, and port statuses.

💡CLI

The 'Command Line Interface' (CLI) is a text-based interface for interacting with network devices. It allows users to execute commands by typing them in, which gives more control and flexibility compared to GUI options. The video mentions how the CLI tab is available on certain devices running IOS, such as routers, enabling users to input commands like 'no shutdown' and 'config t' to configure device settings.

💡Global Level

The 'Global Level' is one of the configuration levels within the Config Tab. It allows users to make system-wide changes, such as setting the device's hostname or saving configurations. In the video, this level is where settings like the display name and NVRAM functions (saving and erasing startup configs) are managed. It plays a key role in ensuring that the device’s broader settings are correctly configured.

💡Interface Level

The 'Interface Level' allows users to configure individual network interfaces on a device, such as Fast Ethernet or Gigabit interfaces. The video explains how this level lets users set IP addresses, MAC addresses, and turn ports on or off (equivalent to the 'no shutdown' command). It highlights the importance of configuring these interfaces for devices to communicate in a network.

💡IP Address

An 'IP Address' is a unique identifier assigned to devices on a network, allowing them to communicate with each other. In the video, users configure devices such as routers and PCs with IP addresses (e.g., 192.168.1.1) via the Config Tab or CLI. Setting a correct IP address is essential for device communication and routing in any network setup.

💡Subnet Mask

The 'Subnet Mask' defines the network and host portions of an IP address, determining the size of the network. In the video, the default subnet mask is automatically provided when an IP address is entered in the Config Tab. This concept is crucial for understanding how devices group together in the same network segment.

💡NVRAM

NVRAM, or Non-Volatile Random Access Memory, stores the device’s startup configuration, which persists across reboots. In the video, users can save the running configuration to NVRAM (known as 'save to NVRAM'), or erase it. This ensures that configurations are not lost when the device is powered off.

💡Routing Level

The 'Routing Level' in the Config Tab allows users to set routing configurations on devices that support routing protocols, such as routers. The video mentions this level as a place to manage routing settings, which control how data packets are directed between different networks. This is critical for enabling inter-network communication.

💡Services Tab

The 'Services Tab' is a section in Cisco Packet Tracer available only on server devices, allowing the configuration of services like HTTP, DHCP, and DNS. The video demonstrates how this tab enables users to activate, deactivate, or modify the settings of various network services, such as turning on an HTTP server or setting DNS configurations. It shows the server’s role in providing network services.

💡AAA Accounting

'AAA Accounting' is a security framework for controlling user access to network resources, tracking usage, and logging activity. In the video, this feature is available exclusively on the server within the Services Tab. It provides a way to monitor and account for user activities on the network, which is important for maintaining security and managing network resources.

Transcripts

hello and welcome to this episode of Packet Tracer in this episode we want to

talk about using the config tab to configure devices so let's get started

the purpose of using the config tab is to configure the device using a GUI

display instead of the CLI mode we can of course configure any aspect of the

device using the CLI but this config tab provides us with a UI that's much easier

to configure some common settings on this device

it is divided into four General level the global level the routing switching

and interface level let's go here to the global level we have the settings the

display name of how this router or how this device will display in Packet

Tracer the host name is the name of this device in iOS config file if we try to

erase the NV Ram that means to erase the conf Startup configuration and of course

we try to save to nvram that means saving running convict to nv-ram saving

running running config to Startup config we can export both the startup config

and the running config and they will be exported inside txt files

we can also load the startup file using a txt file or merge the running config

using a txt file and as such we have the routing and the

switching levels as well the routing level provides us with some basic

abilities to configure routing on this device and the switching gives us some

ability to configure vlans on this device

and of course the interface provides us with the ability to configure interfaces

on this device if I turn on this port status that is

equivalent of no shutdown in the CLI

we can configure the MAC address as we want to by default the MAC address is

provided for us we can configure the IP address let me configure one IP address

in here 192. 168

.1.1 and if I click on subnet mask field then

a default subnet mask will be provided for me

and when I close this window the settings are saved

now let's go to this PC and see how we can configure this PC using the config

tab in the PC we have only two levels of configuration the global level and the

interface level in the global settings we have the display name we have the

interfaces and we also have the ability to

configure a Gateway using DHCP or static IP addresses and we can also configure

the DNS server we can configure the ipv6d Gateway as well in here and the

DNS server as well if we go to the interface fast ethernet 0 we again have

the ability to configure this interface using DCP or static IP address

let's configure this one to 192 168 1.2 and if I click here default subnet mask

is going to be provided for me and that's it about using config tab to

configure devices I hope to see you in the next episode and stay tuned hello

and welcome to this episode of package racer in this episode we want to talk

about using the desktop tab so not all devices have that desktop tab let's go

to the router as you can see we don't have a desktop Tab in a router but let's

go to the PC and we do have a desktop tab

here in the ipconfiguration we can change the IP configuration of this

device as you can see I have some IP configurations already I can change it

to DCP or I can set up some static IP addresses on my own 192 168 2.5

with a default subnet mask and if I copy this to the default gateway and change

this to the one that is my default gateway now let's close this

now the settings is saved When I close it you can see that we have other apps

in here as well we have the dial up if we want to set up a modem Network then

the dial up tab will be useful for us we have a terminal so that if we want to

access a device a router or a switch using the SSH or telnet applications

then terminal will be very useful for us we have the command prompt maybe we can

use the command prop to show the ipconfig of this device as you can see

the command prompt works the same as if it was on a real computer although not

all commands are available in Packet Tracer we also have web browser if we

want to browse HTTP web pages on a server then we can use the web browser

and we do have a lot of other applications that we will go through

them later on in this course now let's close this and go to the server the

server also has as this desktop tab as you can see not all of the applications

that was available on the PC is available on the server but the one

thing that's more specific to the server is this Triple A accounting this is only

available to the server and not available on desktop and that's it for

this episode everyone I hope this has been informative for you and I would

like to see you in the next episodes stay tuned hello and welcome to this

episode of Packet Tracer in this episode we want to discuss using the services

tab so let's go to this router as you can see the router doesn't have a

Services tab because it does not apply to a router to provide services like a

server now let's go to the PC as well as you

can see in the PC we also don't have the services tab as well because the PC does

not provide any services let's go to the server because this is a

server that's why we have the services tab available

in the services tab as you can see there are many services that this server can

provide for us such as HTTP DHCP tftp DNS and all of those and if I click on

any of these Services then I have the ability to turn off and on that service

or to manipulate some settings for that service

let's go to the HTTP setting as you can see by default the server is an HTTP

server and some HTML pages are also available for serving so we can test out

the services of HTTP on this server from this PC if we go to the desktop tab to

web browser

and if I try to enter the IP address of the server 192 168.2.1

then if I click go you can see that the Cisco Packet Tracer web page has opened

for us and that verifies that the server is running good and well

and that's it for this episode everyone I hope this has been informative for you

and I would like to see you in the next episode Stitch hello and welcome to this

episode of Packet Tracer in this episode we are covering using the CLI tab of the

devices so let's go to the PC as you can see

here we don't have any CLI tab for the PC and we don't have a CLI tab for the

server as well the CLI tab is only available for the

devices that they run the IOS operating system so that's why we have the CLI tab

to configure these devices using the IOS command line interface

now let's get started let's enter a few commands like enable

config t interface fast ethernet 0 0 slash zero

and here I am I think it's a gigabit interface

interface gig zero slash zero slash zero and now here I am in the interface

configuration mode I can issue a no shutdown command

and I can set an IP address as well IP address 192.

168 1.1 with a default subnet mask and that's it you see that the CLI tab

works as if it was on a real device to see the list of all of available iOS

commands you can refer to the help files we do have the ability to paste into the

CLI or to copy from the CLI using these two buttons

and that's it for this episode everyone I hope this has been informative for you

and I would like to see you in the next episode
