Accessing and Monitoring an IoT Network
Explore a Smart Home
Packet Tracer has a wide variety of sensors and smart devices that will allow you to design smart homes, smart cities, smart factories, and smart power grids.
To locate the available sensors and smart devices, select End Devices from the Device Selection box at the lower left-hand side of the screen. Next, select the subcategory Home. In this subcategory, you will see many IoT devices including an air conditioner, ceiling fan, coffee maker, and CO detector. These devices can be connected to your network wirelessly or with a physical cable.
To connect the devices to your network, you need a home gateway or registration server. To find a home gateway, select Network Devices from the Device Selection box and then select Wireless Devices from the subcategories.
To control the devices, you have two options:
1. You can interact directly with a device. Hold down the Alt key and at the same time click on the device to turn it on or off.
2. You can connect remotely over the network. Using a remote PC, tablet or smart phone, use a web browser to connect to the home gateway or registration server. From here, you can turn the devices on or off using the features of the home gateway or registration server.
To configure devices, click on the device to open it. After it is opened, multiple tabs are displayed:
• Specifications – describes the features, usage, local and remote control of the device
• Physical – available modules and power connections
• Config – shows display name, serial number, network configuration, and IoT server
• Attributes – displays the device attributes such as MTBF, power consumption, and cost
To configure the home gateway, click on the device. Within the device multiple tabs are displayed:
• Physical – available modules, and power
• Config – shows display name, interfaces (Internet, LAN, and wireless) to be configured
• GUI – shows services to be turned on/off
• Attributes – shows features and values related to device such as mean time between failure (MTBF), cost, power sources, and wattage

IOS CLI Primary Command Modes
The IOS CLI (Command Line Interface) on Cisco devices provides several primary command modes, each with a specific set of commands and functionality. These modes are:
User EXEC mode: This is the default mode you enter when you first connect to a Cisco device. In this mode, you can only run a limited set of commands, such as basic monitoring commands and show commands. The prompt for user EXEC mode is typically a ">" symbol.
Privileged EXEC mode: To access more advanced configuration and troubleshooting commands, you need to enter privileged EXEC mode. This mode is indicated by a "#" symbol at the end of the prompt. You can enter privileged EXEC mode by using the "enable" command and providing the correct password.
Global configuration mode: This mode allows you to configure global parameters on the device, such as hostname, domain name, and interfaces. To enter this mode, you use the "configure terminal" command from privileged EXEC mode. The prompt for global configuration mode is typically "(config)#".
Interface configuration mode: Once you have entered global configuration mode, you can then configure individual interfaces using interface configuration mode. You can enter this mode by specifying the interface you want to configure (e.g. "interface gigabitethernet0/1") and then using the "interface" command. The prompt for interface configuration mode typically shows the interface type and number, followed by "(config-if)#".
Line configuration mode: This mode is used to configure settings for specific lines, such as console or telnet lines. To enter line configuration mode, you use the "line" command from global configuration mode. The prompt for line configuration mode typically shows the line type and number, followed by "(config-line)#".
Router configuration mode: This mode is used specifically for configuring routing protocols on a Cisco router. To enter router configuration mode, you use the "router" command from global configuration mode, followed by the routing protocol you want to configure (e.g. "router ospf 1"). The prompt for router configuration mode typically shows the name of the routing protocol, followed by "(config-router)#".
Each of these primary command modes provides a different level of functionality and access to the configuration and monitoring commands available on a Cisco device. By understanding these modes and how to navigate between them, you can effectively manage and troubleshoot your Cisco network.

Protecting Against Malware
Video Explanation – Protecting Against Malware
Malware, short for malicious software, refers to any software that is designed to harm or exploit computer systems, networks, or mobile devices. It can take many forms, including viruses, trojans, worms, spyware, ransomware, and adware. Malware can cause a range of problems, from slowing down your device and stealing your personal data to damaging your files or rendering your device unusable.
Protecting against malware is essential for keeping your device and personal data safe. Here are some ways to protect yourself against malware:
Install antivirus software: Antivirus software is designed to detect and remove malware from your device. It can also prevent malware from infecting your device in the first place. Be sure to keep your antivirus software up-to-date with the latest virus definitions to ensure the best protection.
Keep your software up-to-date: Outdated software can contain vulnerabilities that malware can exploit. Keep your operating system, applications, and plugins up-to-date with the latest security patches.
Be cautious of downloads and email attachments: Be careful when downloading files or email attachments from unknown sources. Malware is often spread through infected files and links.
Use strong passwords: Strong passwords make it harder for hackers to access your device and personal data. Avoid using simple, easy-to-guess passwords, and use different passwords for different accounts.Malware, short for malicious software, refers to any software that is designed to harm or exploit computer systems, networks, or mobile devices.

video demonstration of the show ip interface brief command
The show ip interface brief
command is used in Cisco networking devices to display a summary of the configuration and status of all interfaces on the device. Here's a demonstration of the command:
- First, log in to the Cisco device using the terminal or console connection.
- Enter the privileged EXEC mode by typing
enable
and providing the enable password if required. - Type
show ip interface brief
and press Enter.
Here is an example output of the command:
objectivecRouter# show ip interface brief
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 10.0.0.1 YES NVRAM up up
GigabitEthernet0/1 192.168.1.1 YES NVRAM up up
Serial0/0/0 unassigned YES NVRAM down down
Serial0/1/0 unassigned YES NVRAM administratively down down
In the example output above, there are four interfaces listed: GigabitEthernet0/0
, GigabitEthernet0/1
, Serial0/0/0
, and Serial0/1/0
. The columns provide the following information:
Interface
: the name of the interfaceIP-Address
: the IP address assigned to the interface (if any)OK?
: whether the interface is operational (YES) or not (NO)Method
: the method used to assign the IP address to the interface (in this case, NVRAM)Status
: the status of the interface (up or down)Protocol
: the routing protocol currently in use on the interface (if any)
The output shows that GigabitEthernet0/0
and GigabitEthernet0/1
are both up and have IP addresses assigned to them, while Serial0/0/0
and Serial0/1/0
are both down and do not have IP addresses assigned to them.
