TAILIEUCHUNG - Catalyst 2900 Password Recovery

You have just taken a job at a company that uses Catalyst 2900 Ethernet switches in their IDFs. The person that managed the network before you did not leave any documentation containing the passwords. Perform password recovery on the Catalyst 2900 - change the user exec password to “cisco” and the privileged exec mode password to “class”. | Lab Catalyst 2900 Password Recovery Console Cable ALSwitch 2900XL 24 Workstation 24 Objective Regain control of a Cisco Catalyst 2900 Ethernet switch after you have lost the passwords. Scenario You have just taken a job at a company that uses Catalyst 2900 Ethernet switches in their IDFs. The person that managed the network before you did not leave any documentation containing the passwords. Perform password recovery on the Catalyst 2900 - change the user exec password to cisco and the privileged exec mode password to class . Lab Tasks 1. First configure your 2900 switch to the diagram above. You can skip this step if you already have the Lab 2900 initial setup configured. Switch enable Switch Set the switch name. Switch config terminal Switch config host ALSwitch ALSwitch config 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. ALSwitch config enable password somethingdifferent ALSwitch config line con 0 ALSwitch config-line password somethingelse ALSwitch config-line login ALSwitch config-line line vty 0 15 ALSwitch config-line password somethingelse ALSwitch config-line login ALSwitch config interface vlan 1 ALSwitch config-if ip address Configure the IP address of your workstation to 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 2900 series of switches deals with password recovery in a similar fashion to other IOS devices. The idea is to move the current startup config out of the way so that the switch loads the default config which has no passwords. Once the switch is up and running we get into enable mode move the saved startup config into running config modify the passwords and then move it back into the startup config. 3. Make sure you are connected to the console .
