This section includes information on configuring local users, RADIUS schemes, HWTACACS schemes,
and LDAP schemes.
Configuring local users
To implement local authentication, authorization, and accounting, create local users and configure user
attributes on the device. The local users and attributes are stored in the local user database on the device.
A local user is uniquely identified by the combination of a username and a user type. Local users are
classified into the following types:
• Device management user—User who logs in to the device for device management.
• Network access user—User who accesses network resources through the device.
Configurable local user attributes are:
• Service type.
Services that the user can use. Local authentication checks the service types of a local user. If none
of the service types is available, the user cannot pass authentication.
Service types include FTP, SSH, Telnet, and terminal.
• User state.
Whether or not a local user can request network services. There are two user states: active and
blocked. A user in active state can request network services, but a user in blocked state cannot.
• User group.
Each local user belongs to a local user group and bears all attributes of the group, such as the
password control attributes and authorization attributes. For more information about local user
group, see "Configuring user group attributes."
• A
uthorization attributes.
Authorization attributes indicate the rights that a user has after passing local authentication.
Authorization attributes include the ACL, idle cut function, user role, VLAN, and FTP/SFTP work
directory. For support information about authorization attributes, see "Configuring local user
attributes."
Every c
onfigurable authorization attribute has its definite application environments and purposes.
When you configure authorization attributes for a local user, consider which attributes are needed
and which are not.
You can configure an authorization attribute in user group view or local user view to make the
attribute effective for all local users in the group or for only the local user. The setting of an
authorization attribute in local user view takes precedence over the attribute setting in user group
view.
• Password control attributes.
Password control attributes help you control password security for device management users.
Password control attributes include password aging time, minimum password length, and
password composition policy.
You can configure a password control attribute in system view, user group view, or local user view,
making the attribute effective for all local users, local users in a group, or only the local user. A
password control attribute with a smaller effective range has a higher priority. For more
