Parameters

aging: Enables the password expiration feature.

composition: Enables the password composition restriction feature.

history: Enables the password history management feature.

length: Enables the minimum password length restriction feature.

Usage guidelines

In non-FIPS mode:

· In Release 6607:

¡ The composition and length features are enabled by default and can take effect only when the global password control is enabled.

¡ For the aging or history feature to take effect, you must enable both the global password control and the aging or history feature.

· In Release 6616 and later:

¡ The composition and length features can take effect regardless of whether the global password control is enabled or not.

¡ For the aging or history feature to take effect, you must enable both the global password control and the aging or history feature.

In FIPS mode, for a password restriction feature (the aging, composition, history, or length) to take effect, you must enable both the global password control and the specific password restriction feature.

For device management users, if the password is set in hashed form, the password restriction settings do not take effect even the global password control and the specific restriction are enabled. For more information about password configuration for device management users, see "Configuring AAA."

If the password history management is disabled, the system will not compare the new password with history passwords, but the system will not stop recording history passwords. When the number of history password records of a user reaches the maximum number set by the password-control history command, the newest history record overwrites the earliest one.

Examples

# Enable the password control feature globally.

Parameters

aging-time: Specifies the password aging time in days, in the range of 1 to 365.

Usage guidelines

The aging time depends on the view:

· The time in system view has global significance and applies to all user groups.

· The time in user group view applies to all local users in the user group.

· The time in local user view applies only to the local user.

A password aging time with a smaller application scope has higher priority. The system prefers to use the password aging time in local user view for a local user.

· If no password aging time is configured for the local user, the system uses the password aging time for the user group to which the local user belongs.

· If no password aging time is configured for the user group, the system uses the global password aging time.

Examples

# Globally set the passwords to expire after 80 days.

Usage guidelines

By default, the password control blacklist feature is enabled only for FTP, and VTY users when you enable the global password control feature. To enable the password control blacklist feature for login users on both AUX and VTY lines, you must also execute this command. For more information about user lines, see login management configuration in in Fundamentals Configuration Guide.

With this feature enabled, the number of consecutive login failures on the same user account is accumulated for users on AUX lines. If the number reaches the limit for console, AUX, TTY, and USB users, the system adds the user account to the blacklist and takes corresponding action.

Use password-control login-attempt to configure the maximum number of consecutive login failures and the action to be taken when the maximum number is reached.

Predefined user roles

network-admin

Usage guidelines

The system checks for weak login passwords for Telnet, SSH, HTTP, or HTTPS device management users. A password is weak if it does not meet the following requirements:

· Password composition restriction.

· Minimum password length restriction.

· Password complexity checking policy.

By default, the system displays a message about a weak password but does not force the user to change it. To improve the device security, you can enable the mandatory weak password change feature, which forces the users to change the identified weak passwords. The users can log in to the device only after their passwords meet the password requirements.

To view the password control settings, use the display password-control command. To change the password composition restriction, minimum password length, and password complexity checking policy, use the password-control composition, password-control length and password-control complexity commands, respectively.

Examples

# Enable the mandatory weak password change feature.

<Sysname> system-view

[Sysname] password-control change-password weak-password enable

Use undo password-control complexity to remove a password complexity checking item.

Syntax

password-control complexity { same-character | user-name } check

undo password-control complexity { same-character | user-name } check

Default

In non-FIPS mode:

· In Release 6607, the global password complexity checking policy is that both username checking and repeated character checking are disabled. The password complexity checking policy for a user group equals the global setting. The password complexity checking policy for a local user equals that of the user group to which the local user belongs.

· In Release 6616 and later, the global password complexity checking policy is that username checking is enabled and repeated character checking is disabled. The password complexity checking policy for a user group equals the global setting. The password complexity checking policy for a local user equals that of the user group to which the local user belongs.

In FIPS mode:

· The global password complexity checking policy is that both username checking and repeated character checking are disabled.

· The password complexity checking policy for a user group equals the global setting. The password complexity checking policy for a local user equals that of the user group to which the local user belongs.

Parameters

same-character: Refuses a password that contains a minimum of three consecutive identical characters. For example, the password aaabc is not complex enough.

user-name: Refuses a password that contains the username or the reverse of the username. For example, if the username is 123, a password such as abc123 or 321df is not complex enough.

Usage guidelines

The password complexity checking policy depends on the view:

· The policy in system view has global significance and applies to all user groups.

· The policy in user group view applies to all local users in the user group.

· The policy in local user view applies only to the local user.

A password complexity checking policy with a smaller application scope has higher priority. The system prefers to use the password complexity checking policy in local user view for a local user.

· If no policy is configured for the local user, the system uses the policy for the user group to which the local user belongs.

· If no policy is configured for the user group, the system uses the global policy.

In non-FIPS mode:

· In Release 6607, both username checking and repeated character checking are disabled by default and they can take effect only after the global password control is also enabled.

· In Release 6616 and later, username checking is enabled by default regardless of whether global password control is enabled or not.

In FIPS mode, both username checking and repeated character checking are disabled by default and they can take effect only after the global password control is also enabled.

You can enable both username checking and repeated character checking.

password-control composition

Use password-control composition to configure the password composition policy.

Use undo password-control composition to restore the default.

Syntax

password-control composition type-number type-number [ type-length type-length ]

undo password-control composition

Default

In non-FIPS mode:

· In Release 6607, the password using the global composition policy must contain a minimum of one character type and a minimum of one character for each type.

· In Release 6616 and later, the password using the global composition policy must contain a minimum of two character types and a minimum of one character for each type.

· The password composition policy for a user group is the same as the global policy. The password composition policy for a local user is the same as that of the user group to which the local user belongs.

In FIPS mode:

· The password using the global composition policy must contain a minimum of four character types and a minimum of one character for each type.

Parameters

type-number type-number: Specifies the minimum number of character types that a password must contain. The value range for the type-number argument is 1 to 4 in non-FIPS mode and fixed at 4 in FIPS mode.

type-length type-length: Specifies the minimum number of characters that are from each type in the password. The value range for the type-length argument is 1 to 63 in non-FIPS mode, and 1 to 15 in FIPS mode.

Usage guidelines

The password composition policy depends on the view:

· The policy in system view has global significance and applies to all user groups.

· The policy in user group view applies to all local users in the user group.

· The policy in local user view applies only to the local user.

A password composition policy with a smaller application scope has higher priority. The system prefers to use the password composition policy in local user view for a local user.

· If no policy is configured for the local user, the system uses the policy for the user group to which the local user belongs.

· If no policy is configured for the user group, the system uses the global policy.

The product of the minimum number of character types and minimum number of characters for each type cannot be greater than the maximum length of passwords.

Parameters

network-class: Enables global password control for network access users. If you do not specify this keyword, the command enables global password control for device management users.

Usage guidelines

When you enable global password control, the device automatically generates a .dat file and saves the file to the storage media. The file is used to record authentication and login information of local users. Do not manually delete or modify the file.

The password composition policy, minimum password length, and username checking are independent of the global password control feature. Other password control features (such as password expiration and password history management) take effect only after global password control and the specific password control features are enabled.

After the global password control feature is enabled for device management users, you cannot display the password and super password configuration for device management users by using the corresponding display commands.

After the global password control feature is enabled for network access users, you cannot display the password configuration for network access users by using the corresponding display commands.

You can configure all password control features for device management users.

You can configure only the following password control features for network access users:

· Password complexity checking policy.

· Password composition policy.

· Minimum password length.

· Minimum password update interval.

· Maximum number of history password records for each user.

Parameters

max-record-number: Specifies the maximum number of history password records for each user. The value range is 2 to 15.

Usage guidelines

The global password control feature enables the system to record history passwords. When the number of history password records of a user reaches the maximum number, the newest history record overwrites the earliest one.

To delete the existing records, use one of the following methods:

· Use the undo password-control enable command to disable the password control feature globally.

· Use the reset password-control history-record command to clear the passwords manually.

Examples

# Set the maximum number of history password records for each user to 10.

Parameters

length: Specifies the minimum password length in characters. The value range for this argument is 4 to 32 in non-FIPS mode, and 15 to 32 in FIPS mode.

Usage guidelines

The minimum length setting depends on the view:

· The setting in system view has global significance and applies to all user groups.

· The setting in user group view applies to all local users in the user group.

· The setting in local user view applies only to the local user.

A minimum password length with a smaller application scope has higher priority. The system prefers to use the minimum password length in local user view for a local user.

· If no minimum password length is configured for the local user, the system uses the minimum password length for the user group to which the local user belongs.

· If no minimum password length is configured for the user group, the system uses the global minimum password length.

Examples

# Set the global minimum password length to 16 characters.

<Sysname> system-view

[Sysname] password-control length 16

# Set the minimum password length to 16 characters for the user group test.

Parameters

exceed: Specifies an action if the user fails the maximum number of consecutive login attempts.

· lock: Locks the user permanently.

¡ For FTP or VTY users, the user account and the user's IP address are both locked. No one can use this user account to log in from this locked IP address.

¡ For AUX users, the user account is locked. A user cannot use this user account to log in through an AUX user line.

· lock-time time: Locks the user for a period of time. The value range for the time argument is 1 to 360 minutes.

¡ When the locking timer expires, the FTP or VTY user can use this user account to log in from the IP address again.

¡ When the locking timer expires, the AUX user can use this user account to log in again.

· unlock: Does not lock the user account.

¡ The FTP or VTY user can continue using this user account to make login attempts from the current IP address.

¡ The AUX user can continue using this user account to make login attempts.

Usage guidelines

The login-attempt policy depends on the view:

· The policy in system view has global significance and applies to all user groups.

· The policy in user group view applies to all local users in the user group.

· The policy in local user view applies only to the local user.

A login-attempt policy with a smaller application scope has higher priority. The system prefers to use the login-attempt policy in local user view for a local user.

· If no policy is configured for the local user, the system uses the policy for the user group to which the local user belongs.

· If no policy is configured for the user group, the system uses the global policy.

If an FTP or VTY user fails to log in, the system adds the user account and the user's IP address to the password control blacklist. If an AUX user fails to log in, the system adds the user account to the password control blacklist. When the maximum number of consecutive login failures is reached, the login attempt limit feature is triggered.

Whether a blacklisted user and user account are locked depends on the locking setting:

· If a user account is permanently locked for a user, the user cannot use this account unless this account is removed from the password control blacklist. To remove the user account, use the reset password-control blacklist command.

· To use a temporarily locked user account, the user can perform either of the following tasks:

¡ Wait until the locking timer expires.

¡ Remove the user account from the password control blacklist.

· If the user account and the user are blacklisted but not locked, the user can continue using this account to log in. The account and the user's IP address are removed from the password control blacklist when the user uses the account to successfully log in to the device.
