Open’up’the’program.’ 2. Configure the link between R1 and R2 to be on the network 192.168.12.0/24. SSH is enabled automatically when an RSA key pair is generated. Configure password encryption on the switch using the global configuration command6. InfoSec institute respects your privacy and will never use your personal information for anything other than to notify you of your requested course pricing. 3. We analyze your responses and can determine when you are ready to sit for the test. It support most routing, switching, wireless, and basic firewall devices with latest IOS.
The articles will give you the background on the topic and walk-through the packet tracer lab. We can then go ahead to the privileged EXEC mode (using the enable command) to begin our configuration. Recommend specific skills to practice on next Even if we use the service password-encryption command, the encryption algorithm offered by this command is so weak. Banners can act like warning signs and may be helpful in legal prosecution. Configure Switch hostname as LOCAL-SWITCH, Configure the message of the day as "Unauthorized access is forbidden", Configure the password for privileged mode access as "cisco".
The configuration to achieve this task on R2 is as follows: To verify that only SSH is allowed, let’s try to open a Telnet connection to R2: Note: On a real device, it will not say “Open” and then close. We analyze your responses and can determine when you are ready to sit for the test. He's a CCIE (Security) with a new found love in writing. Track your progress towards a certification exam, By Tolulope Ogunsina on February 27, 2015, By Tolulope Ogunsina on February 26, 2015, By Tolulope Ogunsina on February 25, 2015, By Tolulope Ogunsina on February 24, 2015, Skillset library of over 100,000 practice test questions, Troubleshooting Routers, Switches and Wireless Networks. Configure an enable password of “cisco123” on R1 and also a password of “cisco123” on the VTY lines. He has multiple years of experience in the design, implementation and support of network and security technologies. The need to have solid understanding of subnets is at the very heart of successfully cracking the Cisco certification. The password must be md5 encrypted5. Also set the clocks on the devices to the current date and time. Along your journey to exam readiness, we will: 1. Which required skills you need to work on The configuration to meet this task on the devices is as follows: One of the easiest ways to verify your interface settings is to use the show ip interface brief command because it gives a nice summary of the interfaces, their IP addresses and their link/protocol status: From a security standpoint, configuring an enable password is not recommended because it is stored in clear text in the router’s configuration.
There are a couple of things to note if you want to use SSH to manage a Cisco device remotely: This task also requires that different users be placed at different privilege levels. Imagine typing a semester paper in Microsoft Word and forgetting to save.
We can restrict what protocol is allowed to be used to remotely manage a Cisco router by using the transport input line configuration command. A new switch just purchased from Cisco contains no default configuration. Configure a username of “cisco” with a password of “cisco123” on R2. When you turn on a new Cisco IOS device and connect to it via the console, you may see the System Configuration Dialog shown below which can help you configure basic settings on the device: I have not used this System Configuration Dialog in the real world and I’m not sure I know anyone who has so we just answer “no” and are presented with the router prompt (User EXEC mode). Come see why we have the highest pass rates in the industry! You need to configure the switch with setup mode or from scratch using the command line interface (CLI) before connecting it in your network environment.
You also need to generate an RSA key pair of at least 768 bits for SSHv2 to be enabled.
All of the exam prep you see here & their lab files will always be free to you. Configure the message of the day as "Unauthorized access is forbidden"4. To view this banner, we can open a telnet connection to R1: One of the most important things you should remember to do is save the configuration you have made on your devices (and back them up). Therefore, the configuration on R2 is as follows: We can test this configuration by opening SSH connections to the router (from the router itself or you can use R1): Task 5: Exec-timeout and Remote Access Protocol Restriction. However, since that is what the task asks for, let’s go ahead with the configuration: To confirm that the passwords are not stored in clear text (due to the service password-encryption command), we can view the running configuration: Hint: To see how easy it is to crack this type of password, paste “0822455D0A16544541” in the ‘Type 7 Password’ field on this web page: http://www.ifm.net.nz/cookbooks/passwordcracker.html.
Ensure that the passwords are not stored in clear-text in the configuration.

Packet’Tracer’For’BeginnersTutorial’ Part1’ 1. Adeolu Owokade is a technology lover who has always been intrigued by Security. There are a couple of ways to save like using the copy run start (short for copy running-config startup-config) or using the write memory command.
93%+ Pass Rate, come see why with our award winning CCNA training!
This lab will test your ability to configure basic settings such as hostname, motd banner, encrypted passwords, and terminal options on a Cisco Catalyst 2960 switch simulated in Packet Tracer 126.96.36.199. 2. As a Cisco certified professional (CCENT or CCNA), it is very important to know the basic Cisco switch configuration commands to improve the performances and the security of the enterprise network. Configure Switch hostname as LOCAL-SWITCH3.
To set the clock on a Cisco router, we use the clock set command which is actually an EXEC level command (not global configuration mode).
Our lab setup for this article is very simple as shown below: … Get the latest news, updates & offers straight to your inbox! Ensure that the devices do not lose their configuration even if they are restarted.
While going through the Packet Tracer labs on the Intense School site, I noticed that there was none that covered the basic router configurations using the CLI (Section 4.2 of the exam objectives) and so, we will be doing that in this lab.
