Password Policies

GigaVUE‑OS nodes observe several policies designed to ensure strong password protection for user accounts.

Policy	Description
Password Standards	Passwords must meet the following standards: ● include 8-64 characters ● include at least one numeral ● include at least one lower case letter ● include at least one upper case letter ● include at least one special character (for example, !, #, $, %, ^, &, or * – ASCII 0x21, 0x2F, 0x3A, 0x40, 0x5B, 0x5F, 0x7B, 0x7E) Note: The following special characters are not supported: ● " ● / ● ? However, you can use these characters in the password as described in the Reserved Characters in Passwordssection. ● must not include user-name or parts of full-name
Password Recommendations	The following are password recommendations: ● passwords should be configured on all user accounts ● passwords should be changed on default accounts such as monitor accounts ● passwords should be unique, meaning never used elsewhere or at another time ● passwords should not be shared, meaning each user account should have their own password ● passwords should be long, meaning at least 15 to 20 characters ● passwords should be complex, meaning a mix of numerals, upper case letters, lower case letters, and special characters Note:  It is recommended that you do not include the at sign (@) in passwords. Under some circumstances, this can lead to the failure of some CLI commands, such as image fetch or configuration upload. Note:  The monitor account is designed to give a read-only access to the GigaVUE‑OS. The monitor account is disabled by default. To enable it, assign a password to the account. GigaVUE‑FM, GigaVUE‑OS and GigaVUE-OS CLI users can use the monitor account as long as it is enabled (has a password).
Password recommendation for admin users	The default password on the admin account is admin123A!. After the first login, you must change the password to a non-default value in compliance with the password requirements mentioned above. For example: gigamon123A!!.
Password Change Rights	Only admin users can change the passwords of other users. For example, to change the password of the psandoval account, an admin user would use the following command: (config) # username psandoval password <new password>

A secure passwords mode is available. Refer to the “Configuring Secure Passwords Mode” section in the GigaVUE Administration Guide for details, as well as thesystem.

Configure a Password Expiration Duration

Use the following CLI command to configure the number of days before a password expires:

(config) # aaa authentication password expiration duration 20

Refer to aaa authentication for details.

Configure Login Attempts

Use the following CLI command to configure the handling of failed login attempts:

(config) # aaa authentication attempts

Refer to aaa authentication for details.

Reserved Characters in Passwords

This section describes how to use the following reserved characters in passwords:

■

?

■

\

■

"

There are two ways to include these characters in a password:

1. Enter the username without specifying the password

In this technique, you issue the username command and include the password argument, but do not actually specify the password. This causes the system to prompt you for the password, allowing you to enter reserved characters directly. For example:

(config) # username mcabrera passwordPassword: *********Confirm: *********

In this example, you could enter a password using a reserved character as follows—for example, Test123?

2. Include the escape character before each reserved character

Alternatively, you can include reserved characters in a password specified in the username command by using the following:

■

Enclose the entire password in double-quotation marks. In particular, use this technique to include the question mark (?) in a password.

■

Include the escape character, which is the slash (\), before the single quote (") character or before the slash (\) in a password.

The following table shows some sample passwords:

Command	Password Created
username user1 password "Test123?"	Test123?
username user2 password Test123\”	Test123"
username user3 password Test123\\	Test123\
