When SSH is enabled, a user will be authenticated with a username and a password (unlike Telnet that can use only a password). There are a couple of things to note if you want to use SSH to manage a Cisco device remotely: 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: To confirm that the passwords are not stored in clear text (due to the service password-encryption command), we can view the running configuration: However, since that is what the task asks for, let’s go ahead with the configuration: enable password cisco123 Even if we use the service password-encryption command, the encryption algorithm offered by this command is so weak. 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:įrom a security standpoint, configuring an enable password is not recommended because it is stored in clear text in the router’s configuration. The configuration to meet this task on the devices is as follows: ! R1 Fa0/0, Gi0/0) are in the shutdown state so we need to bring them up using the no shutdown command. IP addresses are configured per interface and by default, physical interfaces (e.g. When you change the hostname of a Cisco router, the change is immediate so the only thing we need to verify is our clock settings which can be done using the show clock command: Note: This configuration assumes you are in global configuration mode. Therefore, the configuration on the routers is as follows: ! R1 We configure a hostname using the hostname command.

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).

We can then go ahead to the privileged EXEC mode (using the enable command) to begin our configuration. 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). 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: Note: Do not enable AAA for any of the tasks. Ensure that the devices do not lose their configuration even if they are restarted.
