You have just taken a job at a company that uses Catalyst 4000 Ethernet switches for their backbone. The person who managed the network before you did not leave any documentation containing the passwords. Perform password recovery on the Catalyst 4000 - change the user exec password to “cisco” and the privileged exec mode password to “class”. | Lab 3.3.4.1 Catalyst 4000 Password Recovery Objective Regain control of a Cisco Catalyst 4000 Ethernet switch after you have lost the passwords. Scenario You have just taken a job at a company that uses Catalyst 4000 Ethernet switches for their backbone. The person who managed the network before you did not leave any documentation containing the passwords. Perform password recovery on the Catalyst 4000 - change the user exec password to cisco and the privileged exec mode password to class . Lab Tasks 1. First configure your 4000 switch to the diagram above. You can skip this step if you already have the Lab 3.1.3 4000 initial setup configured. Console enable Console enable set system name DLSwitchl System name set. DLSwitch1 enable Have someone set the passwords in the steps below. Tell them to not use the standard passwords but to make up some of their own. Make sure they do not tell you what they have set them to. DLSwitch1 enable set password Enter old password Because you do not currently have a password just hit enter Enter new password Retype new password Password changed. DLSwitch1 enable set enablepass Enter old password Because you do not currently have a password just hit enter Enter new password Retype new password Password changed. DLSwitch1 enable set interface sc0 10.1.1.250 255.255.255.0 DLSwitch1 enable set interface sc0 1 Configure the IP address of your workstation to 10.1.1.10 24 2. Attempt to telnet into the Catalyst switch. You will not be able to get in because you do not know the passwords. The Catalyst 4000 series of switches deals with password recovery much differently than the other Cisco IOS based devices. To sum it up the Catalyst 4000 series switch does not require a password when logging in from the console port during the first 30 seconds after it has booted up. A password is still required during this time if you are trying to log in via telnet. This is a great example of why physical security of your devices is so important. Anyone
