Security Configuration Guide, Cisco IOS XE Dublin 17.11.x (Catalyst 9500 Switches) - Switch Access Control with Passwords and Privilege Levels [Support] (2023)

Restrictions to control access using switches with passwords and privileges

The following are the restrictions to control access to the switch with passwords and privileges:

Disabling password recovery will not work if you have configured the switch to start manually using thestarter manual Global configuration command. This command produces the bootloader prompt (change:) after turning the switch off and on.
Password validation forenable password Command against common criteria policy does not occur during configuration or reconfiguration of thecommon criteria policy aaa domain. The password is validated against the common criteria policy only during configuration or reconfiguration of theenable common criteria policy domain.

In a high availability configuration, if you reload the active device and then change one of the AAA common criteria policy criteria associated with the enable password setting (so that the password no longer complies with the common criteria) at an instance of time between manual reloading of the active device and standby switch selection, setting the enable password on the standby device fails during bulk synchronization, while setting the enable password on the standby device fails during it still exists on the active device. This configuration mismatch between the active and standby devices triggers a continuous recharge of the standby device. We recommend that you do not change the common criteria policy in an instance of time between manually reloading the active device and selecting the standby switch.

Restrictions and Guidelines for Reversible Password Types

Password types 0 and 7 are replaced with password type 6. Therefore, password types 0 and 7, which were used for console administrator login, Telnet, SSH, webUI, and NETCONF, they should be migrated to password type 6. No action is required if the username and password are of type 0 and 7 for local authentication, such as CHAP, EAP, etc.
If your startup configuration has a type 6 password and you change to a version where the type 6 password is not supported, you may/may be locked out of your device.

Restrictions and Guidelines for Irreversible Password Types

Username secret password type 5 and secret password type 5 enabled should be migrated to the stronger password type 8 or 9. For more information, seeEnable protection and enable secret passwords with encryption.
If the device startup configuration has a hard type 9 secret (password starting with $14$), you can only downgrade to a version where the hard type 9 secret is supported. The convoluted type 9 secret is supported in Cisco IOS XE Gibraltar 16.11.2 and later releases. If your boot configuration has an intricate type 9 secret and you downgrade to a version earlier than Cisco IOS XE Gibraltar 16.11.2, you might be locked out of your device.

Before downgrading to any version where the complicated type 9 secret is not supported, ensure that the type 9 secret (password starting with $9$) should be part of the startup configuration instead of the type 9 secret complicated (password starting with $14$). ) or type 5 secret (password starting with $1$).

If a device is updated fromCisco IOS XE Fuji 16.9.x,Cisco IOS XE Gibraltar 16.10.x, oCisco IOS XE Gibraltar 16.11.xaCisco IOS XE Gibraltar 16.12.x, the type 5 secret is automatically converted to a convoluted type 9 secret (password starting with $14$). For example:username user1 secret 5 $1$dNmW$7jWhqdtZ2qBVz2R4CSZZC0automatically becomesusername user1 secret 9 $14$dNmW$QykGZEEGmiEGrE$C9D/fD0czicOtgaZAa1CTa2sgygi0Law3/cLqPY426. After updating the device, run thewrite memory Command in privileged EXEC mode to have the intricate type 9 secret written permanently to the startup configuration.
Plain text passwords are converted to type 9 irreversible encrypted password.

Use

This is supported byCisco IOS XE Gibraltar 16.10.1and subsequent releases.
Type 4 secret password is not supported.

Information about access control using switches with passwords and privileges

This section provides information on how to control access to the switch with passwords and privileges.

Prevention of unauthorized access

You can prevent unauthorized users from reconfiguring your switch and viewing configuration information. Typically, you want network administrators to have access to your switch while restricting access to users dialing in from outside the network through an asynchronous port, connecting from outside the network through a serial port, or they connect through a terminal or workstation from within the premises. grid.

To prevent unauthorized access to your switch, you must configure one or more of these security features:

At a minimum, you should configure passwords and privileges on each switch port. These passwords are stored locally on the switch. When users try 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.
See Also
Modules 1-4: Network Protection Group Exam Answers - Cisco Exams
For an added layer of security, you can also configure username/password pairs, which are stored locally on the switch. These pairs are assigned to lines or ports and authenticate each user before they can access the switch. If you have defined privilege levels, you can also assign a specific privilege level (with associated rights and privileges) to each username and password pair.
If you want to use username/password pairs, but want to store them centrally on a server instead of locally, you can store them in a database on a firewall. Multiple network devices can use the same database to obtain authentication (and, if necessary, authorization) information from the user.
You can also enable the login enhancements feature, which logs both failed and failed login attempts. Sign-in enhancements can also be configured to block future sign-in attempts after a certain number of failed attempts.

Default Password and Privilege Level Settings

A simple way to provide access control to endpoints on your network is to use passwords and assign privilege levels. Password protection restricts access to a network or network device. Privilege levels define which commands users can enter after they have logged in to a network device.

This table shows the default password and privilege level settings.

Tabla 1.Default password and privilege levels
Feature	Default settings
Enable password and privilege level	No password is defined. The default is level 15 (privileged EXEC level). The password is not encrypted in the configuration file.
Enable secret password and privilege level	No password is defined. The default is level 15 (privileged EXEC level). The password is encrypted before it is written to the configuration file.
line password	No password is defined.

Extra password security

The following sections provide information on masked and non-masked secret passwords.

Secret Password Unmasked

To provide an additional layer of security, particularly for passwords that cross the network or are stored on a Trivial File Transfer Protocol (TFTP) server, you can use theenable password oenable secret Global configuration commands. Both commands accomplish the same thing; that is, you can set an encrypted password that users must enter to access privileged EXEC mode (the default) or any privilege level you specify.

We recommend that you use theenable secret command because it uses an improved encryption algorithm. If you set theenable secret command, has priority over theenable password domain; the two commands cannot be in effect simultaneously.

For a device that loads with no startup configuration, the Enable Secret Password task is a required configuration, whether you selectYeahoNoin it"Do you want to enter the initial configuration dialog?"initial setup wizard prompt. The password must be a combination of upper and lower case letters, special characters, and numbers. You will be prompted to re-enter the value for Enable Secret Password and this password will be hidden.

Security Configuration Guide, Cisco IOS XE Dublin 17.11.x (Catalyst 9500 Switches) - Switch Access Control with Passwords and Privilege Levels [Support] (2)

Use

In some cases where the device is connected to the Internet, Cisco Plug and Play (PnP) can complete the initial setup wizard. In such cases, the enable secret configuration will not be requested.

If you enable password encryption, it is applied to all passwords, including username passwords, authentication key passwords, privileged command password, and virtual terminal line and console passwords.

Masked secret password

Conenable secret command, the password is encrypted but visible in the terminal when you type the password. To mask the password in the terminal, use themasked secret Global configuration command. The encryption type for this password is type 9, by default.

You can use this command to configure a masked secret password for the common criteria policy.

Password recovery

By default, any end user with physical access to the switch can recover a lost password by interrupting the boot process while the switch is powered on and then entering a new password.

The password recovery disable feature protects access to the switch password by disabling some of this functionality. When this feature is enabled, the end user can interrupt the boot process only by agreeing to reset the system to default settings. With password recovery disabled, you can still interrupt the boot process and change the password, but the configuration file (config.text) and the VLAN database file (vlan.dat) are deleted.

If you disable password recovery, we recommend that you save a backup copy of the configuration file on a secure server in case the end user interrupts the boot process and resets the system to default values. Do not save a backup copy of the configuration file on the switch. If the switch is running in VTP transparent mode, we recommend that you also keep a backup copy of the VLAN database file on a secure server. When the switch returns to the system default settings, you can download files saved to the switch using the Xmodem protocol.

To re-enable password recovery, use theno system disable password recovery switchnumber|all Global configuration command.

Terminal Line Telnet Configuration

When you first turn on your switch, it runs an automatic configuration program to assign IP information and create default settings for continued use. The setup program also prompts you to configure your switch for Telnet access via a password. If you did not set this password during the installation program, you can set it when you set a Telnet password for a terminal line.

Username and password pairs

You can configure username and password pairs, which are stored locally on the switch. These pairs are assigned to lines or ports and authenticate each user before they can access the switch. If you have defined privilege levels, you can also assign a specific privilege level (with associated rights and privileges) to each username and password pair.

Privilege levels

Cisco devices use privilege levels to provide password security for different levels of switch operation. By default, 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. By setting multiple passwords, you can allow different sets of users to have access to specific commands.

Privilege levels on the lines

Users can override the privilege level you set using theprivilege level Line configuration command logging on to the line and enabling a different privilege level. They can lower the privilege level using thedeactivate domain. If users know the password for a higher privilege level, they can use that password to enable the higher privilege level. You can specify a high level or privilege level for your console line to restrict the use of the line.

For example, if you want many users to have access to theclear line command, you can assign level2security to it and distribute the level 2 password pretty widely. But if you want more restricted access to theto set up command, you can assign level 3 security to it and distribute that password to a more restricted group of users.

Command Privilege Levels

When you set a command to a privilege level, all commands whose syntax is a subset of that command are also set to that level. For example, if you set theshow ip traffic command at level 15, theshow commands andshow ip commands are automatically set to privilege level 15, unless you individually set them to different levels.

AES password encryption and encryption master keys

You can enable strong, reversible 128-bit Advanced Encryption Standard (AES) password encryption, also known as type 6 encryption. To start using type 6 encryption, enable the AES password encryption feature and configure a master encryption key to encrypt and decrypt passwords.

After you enable AES password encryption and configure a master key, all existing and newly created plaintext passwords for supported applications are stored in type 6 encrypted format, unless you disable type 6 password encryption. You can configure the device to convert all existing weakly encrypted passwords to type 6 encrypted passwords.

The type 6 encrypted password that is configured must be compatible with the existing master key in the device's private NVRAM. If it is not supported, the setup fails.

Type 0 and 7 passwords can be automatically converted to type 6 if AES password encryption function and master encryption key are configured.

Use

Type 6 encrypted password for username password is supported sinceCisco IOS XE Gibraltar 16.10.1and subsequent releases. Automatic conversion to password type 6 is supported fromCisco IOS XE Gibraltar 16.11.1and subsequent releases.
Type 6 encrypted password for username password is backwards compatible withCisco IOS XE Gibraltar 16.10.x. If you downgrade to a version earlier thanCisco IOS XE Gibraltar 16.10.1, the type 6 encrypted username password is rejected. After automatic conversion, to prevent an administrator password from being rejected during a downgrade, manually migrate the passwords used for administrator logins (admin access) to irreversible password types.
Type 6 encrypted password for enable password and VTY line password are supported sinceCisco IOS XE Dublin 17.10.1and subsequent releases. Automatic conversion to password type 6 is supported fromCisco IOS XE Dublin 17.11.1and subsequent releases.

How to configure Switch Access with passwords and privileges

The following sections provide information on the various tasks to access the switch with passwords and privileges.

Setting or changing a static enable password

The enable password controls access to privileged EXEC mode. Follow these steps to set or change a static enable password:

Procedure

command or action Aim

Paso 1

to allow

Example:

Device>to allow

Enable privileged EXEC mode.

Enter your password if prompted.

Paso 2

to set up Terminal

Example:

Device#configure terminal

Enter global configuration mode.

Paso 3

to allow[common criteria policy Policy name]password password

Example:

Device (config) #enable password secret321

Define a new password or change an existing password to access privileged EXEC mode.

By default, no password is defined.
ForPolicy name , specify a policy name defined using thecommon criteria policy aaa domain.

Use

oh new model ycommon criteria policy aaa The commands must be configured before attaching thecommon criteria policy password option.
Forpassword , specify a string of 1 to 25 alphanumeric characters. String cannot start with a number, is case sensitive, and allows spaces, but ignores leading spaces. It can contain the question mark character (?) if you precede the question mark with the Crtl-v key combination when creating the password. For example, to create the password abc?123, do the following:
1. Get intoa B C.
2. Get intoCrtl-v.
3. Get into123.
When the system prompts you to enter the enable password, you do not need to precede the question mark with Ctrl-v; you can just enterabc?123 in the password request.

Stage 4

fin

Example:

Device (config) #fin

Exits global configuration mode and returns to privileged EXEC mode.

Enable protection and enable secret passwords with encryption

Follow these steps to set an encrypted password that users must enter to access privileged EXEC mode (the default) or any privilege level you specify:

Procedure

command or action Aim

Paso 1

to allow

Example:

Device>to allow

Enable privileged EXEC mode. Enter your password if prompted.

Paso 2

to set up Terminal

Example:

Device#configure terminal

Enter global configuration mode.

Paso 3

Use one of the following:

enable password[levellevel] {unencrypted password|encryption type encrypted password}
enable secret[levellevel] {unencrypted password|encryption type encrypted password}

Example:

Device (config) #enable password level 12 example 123

Device (config) #enable secret 9 $ 9 $ sMLBsTFXLnnHTk $ 0L82

Define a new password or change an existing password to access privileged EXEC mode.

Defines a secret password, which is saved using a non-reversible encryption method.

(Optional) Tolevel , the range is 0 to 15. Level 1 is the normal user EXEC mode privileges. The default level is 15 (privileged EXEC mode privileges).
Forunencrypted password , specify a string of 1 to 25 alphanumeric characters. String cannot start with a number, is case sensitive, and allows spaces, but ignores leading spaces. By default, no password is defined.

Forencryption type , the options available forenable password They are type 0, 6, and 7, and type 0, 5, 8, and 9 forenable secret . If you specify an encryption type, you must provide an encrypted password, an encrypted password that you copy from another switch configuration. Secret encryption type 9 is more secure, so we recommend that you select type 9 to avoid problems when upgrading or downgrading.

Use

If you do not specify an encryption type for the secret password, the password is automatically converted to type 9. This is applicable inCisco IOS XE Gibraltar 16.10.1and subsequent releases.
If you specify an encryption type and then enter a clear text password, an error will occur.
You can also manually configure type 9 encryption for the secret password using thealgorithm-type scrypt command in global configuration mode. For example:
```
Device (config) #username user1 algorithm type scrypt secret cisco
```
O
```
Device (config) #enable scrypt secret of type algorithm cisco
```
run thewrite memory Command in privileged EXEC mode to write the type 9 secret permanently to the startup configuration.

Stage 4

password encryption service

Example:

Device (config) #password encryption service

(Optional) Encrypts the password when the password is set or when the configuration is written.

Encryption prevents the password from being readable in the configuration file.

Paso 5

fin

Example:

Device (config) #fin

Exits global configuration mode and returns to privileged EXEC mode.
