Post image for LAB: Configuring Passwords

Objective

Passwords are the first line of defense in keeping unauthorized persons out of our network devices. In this lab, you’ll demonstrate that you can successfully configure passwords on Cisco routers and switches.

Topology

You may use any router or switch to complete this exercise. It does not need to be connected to any other devices.

Task 1

Erase any existing startup configuration.

Task 2

Reload the device.

Task 3

Depending on the type of device you’re using, set it’s hostname to either “core-router” or “core-switch”.

Task 4

Set the console password to “cisco”.

Task 5

Set the enable password to “enable”.

Task 6

Exit from the device and log back in, verifying that you were prompted for the passwords and that they were properly configured.

Task 7

Issue the appropriate commands so that no passwords are shown in plain-text in the device’s configuration.

Task 8

Remove the enable password.

Task 9

Set the enable secret to “secret”.

Task 10

Set the VTY password to “letmein” and issue any commands necessary to ensure that users attempting to access the device via telnet or SSH would be required to authenticate before gaining access to the device.
