Switch config-if switchport protected. Configuring Control Plane Protection. This section contains important information for Cisco CP Express. It contains the following sections:. If you bypass Cisco CP Express and use a console or Telnet connection to log into the router, the login and EXEC banners warn you that you must change the username to "cisco" and the password to "cisco" before you log off of the router.

If you do not change the credentials as directed, you will not be able to log into the router the next time that you attempt to do so. The following Cisco IOS releases enforce the one-time use of the default credentials:. Follow the procedure in this section to secure the router by creating a new username and password, to remove the login banner and exec banner warnings, and to save the configuration changes to the router startup configuration.

Note If you log into the router using a Telnet or a console connection but do not complete the steps in this procedure, be aware of the following:. No additional warning is given before you log off.

In this case, you will need to follow the password recovery procedure at the following link:. To secure the router, remove the banner warnings, and save the changes to the router startup configuration, complete the following steps:. Step 1 Connect the blue console port on your router to a serial port on your PC using the light blue console cable, which is included with your router.

Refer to your router's hardware installation guide for instructions. Step 2 Connect the power supply to your router, plug the power supply into a power outlet, and turn on your router.

Refer to your router's quick start guide for instructions. Step 3 Use Hyper Terminal or a similar terminal emulation program on your PC, with the terminal emulation settings of baud, 8 data bits, no parity, 1 stop bit, and no flow control, to connect to your router.

Step 4 When prompted, enter the username cisco and password cisco. Step 5 Enter configuration mode by entering the following command:. Step 6 Create a new username and password by entering the following command:. Replace username and password with the username and password that you want to use. Use the service password-encryption command to encrypt the console, aux, and vty passwords. Issue the show run command. No, the passwords are now encrypted.

Which level of encryption is harder to crack and why? Configure a warning to unauthorized users with a message-of-the-day MOTD banner using the banner motd command. When a user connects to one of the routers, the MOTD banner appears before the login prompt. Does the MOTD banner look like what you created with the banner motd command?

Task 3. Use the show run command to display the running configuration and check the password that is enabled. You still cannot read the password for the new user account. Even though unencrypted 0 was specified because the service password-encryption command is in effect. Display the running configuration. Which hashing method is used for the password? MD5, because the secret password was configured.

What is the difference between logging in at the console now and previously? You are prompted to enter a Username as well as a password. After logging in, issue the show run command. Were you able to issue the command? Enter privileged EXEC mode using the enable command.

Were you prompted for a password? Yes, the new users created will still be required to enter the enable secret password to enter privileged EXEC mode. Were you prompted for a user account? No, the vty lines were not set to use the locally defined accounts as the line 0 console was. Yes, the vty lines are now set to use the locally defined accounts. For added security, set the AUX port to use the locally defined login accounts.

This can help slow down dictionary attacks and help protect the router from a possible DoS attack. Use the login block-for command to configure a 60 second login shutdown quiet mode timer if two failed login attempts are made within 30 seconds. Is the router enabled to watch for login attacks? Yes What is the default login delay? Configure the router to generate system logging messages for both successful and failed login attempts.

The following commands log every successful login and log failed login attempts after every second failed login. What additional information is displayed? All successful logins are logged. Every 2 failed logins are logged. Step 3: Test the enhanced login security login configuration. Attempt to log in with the wrong user ID or password two times. What message was displayed on PCA after the second failed attempt?

Connection to host lost. What message was displayed on PC-A after the attempted Telnet connection? Issue the show login command within 60 seconds. QuietMode status. Router is currently denying logins from all sources. Secure Shell SSH is a network protocol that establishes a secure terminal emulation connection to a router or other networking device.

SSH encrypts all information that passes over the network link and provides. SSH is rapidly replacing Telnet as the remote login tool of choice for network professionals. Note: For a router to support SSH, it must be configured with local authentication, AAA services, or username or password authentication. In this task, you configure an SSH username and local authentication. Use the username command to create the user ID with the highest possible privilege level and a secret password.

Exit to the initial router login screen, and log in with this username. What was the router prompt after you entered the password? The privileged EXEC enable prompt sign. With a privilege level of 15, the login defaults to privileged EXEC mode. Specify a privilege level of 15 so that a user with the highest privilege level 15 will default to privileged EXEC mode when accessing the vty lines.

Other users will default to user EXEC mode. Use the local user accounts for mandatory login and validation, and accept only SSH connections. Note: The login local command should already be configured in a previous step. It is included here to provide all commands if you were doing this for the first time. Note: If you add the keyword telnet to the transport input command, users can log in using Telnet as well as SSH, however, the router will be less secure.

Configure the RSA keys with for the number of modulus bits. The default is , and the range is from to The default SSH timeouts and authentication parameters can be altered to be more restrictive using the following commands. Task 6. What are some capabilities of each? It runs as an executable application without needing to be installed onto your system. Launch PuTTY by double-clicking the putty. Verify that the SSH radio button is selected.

Click Open. Enter the admin username and password cisco in the PuTTY window. You should see at least two users, one for your console connection and another for the SSH interface. Line User Host s Idle Location. Try to open a Telnet session to your router from PC-A.

Were you able to open the Telnet session? No, the Telnet session fails because only SSH is enabled for the vty lines. Enter the user01 username and password user01pass in the PuTTY window to try connecting for user who does not have privilege level of Yes What was the prompt? Use the enable command to enter privilege EXEC mode and enter the enable secret password cisco The role-based CLI access feature allows the network administrator to define views, which are a set of operational commands and configuration capabilities that provide selective or partial access to Cisco IOS EXEC and configuration config mode commands.

A view can define which commands are accepted and what configuration information is visible. Note: Perform all tasks on both R1 and R3. If an administrator wants to configure another view to the system, the system must be in root view. When a system is in root view, the user has the same access privileges as a user who has level privileges, but the root view user can also configure a new view and add or remove commands from the view.

When you are in a CLI view, you have access only to the commands that have been added to that view by the root view user. Use the command enable view to enable the root view. Use the enable secret password cisco If the router does not have an enable secret password, create one now. The admin1 user is the top-level user below root that is allowed to access this router. It has the most authority. The admin1 user can use all show, config, and debug commands.

Use the following command to create the admin1 view while in the root view. Note: To delete a view, use the command no parser view viewname. Associate the admin1 view with an encrypted password. Review the commands that can be configured in the admin1 view. Use the commands? Add all config, show , and debug commands to the admin1 view and then exit from view configuration mode. The Admin2 user is a junior administrator in training who is allowed to view all configurations but is not allowed to configure the routers or use debug commands.

Use the enable view command to enable the root view, and enter the enable secret password cisco The Tech user typically installs end-user devices and cabling. Tech users are only allowed to use selected show commands.

Issue the show ip interface brief command. Were you able to do it as the tech user? Yes, it is one of the allowed commands. Issue the show ip route command. No, it is not one of the allowed commands. Issue the show run command to see the views you created.

For tech view, why are the show and show ip commands listed as well as show ip interface and show ip interface brief? All parts of the command must be listed for the more specific parameters to work. The Cisco IOS Resilient Configuration feature enables a router to secure the running image and maintain a working copy of the configuration so that those files can withstand malicious attempts to erase the contents of persistent storage NVRAM and flash. The feature secures the smallest working set of files to preserve persistent storage space.

No extra space is required to secure the primary Cisco IOS image file. The secure boot-image command enables Cisco IOS image resilience, which hides the file from dir and show commands. The file cannot be viewed, copied, modified, or removed using EXEC mode commands. When turned on for the first time, the running image is secured. The secure boot-config command takes a snapshot of the router running configuration and securely archives it in persistent storage flash.

You can use only the show secure bootset command to display the archived filename. Display the status of configuration resilience and the primary bootset filename. What is the name of the archived running config file and on what is the name based? It is based on the date and time archived by the secure boot-config command.

How can you tell that the Cisco IOS image is still there? The bytes available and bytes used are approximately the same as before minus the space taken by the archived running config file. Step 7: Save the configuration on both routers. Save the running configuration to the startup configuration from the privileged EXEC prompt. Task 2. Note: R2 could also be the master clock source for switches S1 and S3, but it is not necessary to configure them for this lab.

R2 is the master NTP server in this lab. All other routers and switches learn their time from it, either directly or indirectly.

For this reason, you must first ensure that R2 has the correct Coordinated Universal Time set. Configure R2 as the NTP master using the ntp master stratum-number command in global configuration mode. The stratum number indicates the distance from the original source.

For this lab, use a stratum number of 3 on R2. When a device learns the time from an NTP source, its stratum number becomes one greater than the stratum number of its source.

To configure R1, use the global configuration command ntp server hostname. The host name can also be an IP address. The command ntp updatecalendar periodically updates the calendar with the NTP time. Verify that R1 has made an association with R2 with the show ntp associations command. You can also use the more verbose version of the command by adding the detail argument.

It might take some time for the NTP association to form. Log in as admin with password cisco Click Add. Open a console connection to the router, and verify the associations and time on R1 after it has made an association with R2.

Step 1: Install the syslog server. The Kiwi Syslog Daemon is a dedicated syslog server. You can use either with this lab. Both are available as a free version and run with Microsoft Windows. If it is not successful, troubleshoot as necessary before continuing. NTP was configured in Task 2 to synchronize the time on the network. Displaying the correct time and date in syslog messages is vital when using syslog to monitor a network.

If the correct time and date of a message is not known, it can be difficult to determine what network event caused the message. Verify that the timestamp service for logging is enabled on the router using the show run command. Step 3: Configure the logging severity level on R1.

Logging traps can be set to support the logging function.
