How do I configure password security in Cisco IOS?
By default, the Cisco IOS software has two modes of password security: user mode (EXEC) and privilege mode (enable). You can configure up to 16 hierarchical levels of commands for each mode. By configuring multiple passwords, you can allow different sets of users to have access to specified commands.
How do I configure passwords & privileges?
At a minimum, you should configure passwords and privileges at each switch port. These passwords are locally stored on the switch. When users attempt to access the switch through a port or line, they must enter the password specified for the port or line before they can access the switch.
What are Cisco Xe privilege levels?
Cisco devices use privilege levels to provide password security for different levels of switch operation. By default, the Cisco IOS XE software operates in two modes (privilege levels) of password security: user EXEC (Level 1) and privileged EXEC (Level 15). You can configure up to 16 hierarchical levels of commands for each mode.
How to protect user mode in Cisco IOS?
The most simple option to protect user mode is to add a password. Here’s how to do this: First, we need to enter the console settings. Here’s where we have to add two commands: Switch (config-line)#password cisco Switch (config-line)#login We configure a password (cisco) and use the login command to tell Cisco IOS to prompt for this password.

Protecting Passwords with Enable Password and Enable Secret

To provide an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server, you can use either the enable password or enable secret commands. Both commands accomplish the same thing; that is, they allow you to establish an encrypted password that users must enter to access enable mode (the default),

enablepassword[levellevel]{password

Recovering a Lost Enable Password

You can restore access to enable mode on a router when the password is lost using one of the three procedures described in this section. The procedure you use depends on your router platform. You can perform password recovery on most of the platforms without changing hardware jumpers, but all platforms require the configuration to be reloaded. Pass

Recovering a Lost Enable Password

Note Some password recovery requires that a terminal issue a Break signal; you must be familiar with how your terminal or PC terminal emulator issues this signal. For example, in ProComm, the keys Alt-B by default generates the Break signal, and in a Windows terminal you press Break or CTRL-Break. A Windows terminal also allows you to define a func

At the rommon> prompt, enter the initialize command to initialize the router.

This causes the router to reboot but ignore its saved configuration and use the image in Flash memory instead. The system configuration display appears. community.cisco.com

Recovering a Lost Line Password

If your router has the nonvolatile memory option, you can accidentally lock yourself out of enable mode if you enable password checking on the console terminal line and then forget the line password. To recover a lost line password, perform the following steps: TEST-SYSTEM > See the hardware installation and maintenance publication for your product
