Overview of User Accounts

Managing Switch User Accounts

page 8-8

OmniSwitch AOS Release 6 Switch Management Guide

The default user account on the switch is used for storing new user defaults for privileges and profile 
information. This account does not include a password and cannot be used to log into the switch.

At the first switch startup, the default user account is configured for:

• No read or write access.

• No SNMP access.

• No end-user profile.

Any new users created on the switch will inherit the privileges or the end-user profile of the default user 
unless the user is configured with specific privileges or a profile.

The default user settings may be modified. Enter the user command with default as the user name. Note 
that the default user may only store default functional privileges or a default end-user profile. The default 
user cannot be configured with both privileges and a profile.

The following example modifies the default user account with read-write access to all CLI commands:

-> user default read-write all

In this example, any new user that is created will have read and write access to all CLI commands (unless 
a specific privilege or SNMP access is configured for the new user). For more information about configur-
ing privileges, see 

.

The privilege default is particularly important for users who are authenticated via an ACE/Server, which 
only supplies username and password information; or for users who are authenticated via a RADIUS or 
LDAP server on which privileges are not configured. For more information about these servers, see the 
“Managing Authentication Servers” chapter of the OmniSwitch AOS Release 6 Network Configuration 
Guide.

The switch includes global password settings that are used to implement and enforce password complex-
ity when a password is created, modified, and used. These user-configurable settings apply the following 
password requirements to all user accounts configured for the switch:

• Minimum password size.

• Whether or not a password can contain the account username.

• Minimum password character requirements.

• Password expiration.

• Password history.

• Minimum password age.

In addition to global password settings, the switch also includes global user lockout settings that deter-
mine when a user account is locked out of the switch and the length of time the user account remains 
locked.
