Basic Configuration
• FallbackLocal: Determines whether or not the VMR/NPS will fallback to its
own password/username directory when an authentication attempt fails. When
enabled, the VMR/NPS will first attempt to authenticate the password by checking
the TACACS Server; if this fails, the VMR/NPS will then attempt to authenticate the
password by checking its own internal username directory. This parameter offers
three options:

Off: Fallback Local is disabled (Default)

On(AllFailures): Fallback Local is enabled, and the unit will fallback to it's own
internal user directory when it cannot contact the TACACS Server, or when a
password or username does not match the TACACS Server.

On(TransportFailure): Fallback Local is enabled, but the unit will only fallback
to it's own internal user directory when it cannot contact the TACACS Server.
• AuthenticationPort: The port number for the TACACS function. (Default = 49)
• DefaultUserAccess: When enabled, this parameter allows TACACS users to
access the VMR/NPS command mode without first defining a TACACS user account
on the VMR/NPS. When new TACACS users access the VMR/NPS command
mode, they will inherit the default Access Level, Port Access, Plug Access, Plug
Group Access, Service Access and Current/Power Metering parameters that are
defined via the items listed below: (Default = On)
 Enable: Enables/disables the Default User Access function. (Default = On)
 AccessLevel: Determines the default Access Level setting for new TACACS
users. This option can set the default access level for new TACACS users
to "Administrator", "SuperUser", "User" or "ViewOnly." For more information
on Command Access Levels, please refer to Section 5.4.1 and Section 17.2.
(Default = User)
 PortAccess: Determines the default Port Access setting for new TACACS users.
The Port Access setting determines whether or not the account will be allowed
to connect to the serial Setup Port. (Defaults; Administrator and SuperUser =
Always Enabled, User = Disabled)
Note: ViewOnly level accounts cannot be granted access to the Setup Port.
 PlugAccess: Determines the default Plug Access setting for new TACACS
users. (Defaults; Administrator and SuperUser = All Plugs On,
User = All Plugs Off, ViewOnly = All Plugs Off)
Notes:
• Administrator and SuperUser level accounts always have access to all plugs.
• User level accounts will only have access to the plugs that are defined via the
"Plug Access" parameter.
• ViewOnly accounts are not allowed to invoke switching and reboot
commands.
