NPort 6000 Series User’s Manual Configuring Serial Port Operation Modes
7-23
Authentication type (default=None): This field allows you to configure the method used, if any,
to verify a user’s ID and authorization.
Option Description
Local
Verify the ID against the NPort 6000 User Table.
RADIUS
Verify the ID against the external RADIUS server.
RADIUS - Local
Radius authentication is tried first, switching to Local if unsuccessful.
Local - RADIUS
Authentication is performed locally first, switching to Radius if
unsuccessful.
TACACS+
Verify the ID against the external TACACS+ server.
TACACS+ - Local
TACACS+ authentication is tried first, switching to Local if unsuccessful.
Local - TACACS+
Authentication is performed locally first, switching to Radius if
unsuccessful.
None
Authentication is not required.
Try next type on authentication denied (default=Disable): The field enables or disables the
system to try next type on first authentication denied.
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for
a response to “keep alive” packets before closing the TCP connection. The NPort 6000 checks
connection status by sending periodic “keep alive” packets. If the remote host does not respond to
the packet within the time specified in this field, the NPort 6000 will force the existing TCP
connection to close. For socket and device control modes, the NPort 6000 will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0,
the TCP connection will remain open even if there is no response to the “keep alive” packets.
Inactivity time (default=0 min): This field specifies how long the NPort 6000 will wait for
incoming and outgoing data through the serial port before closing the TCP connection. The TCP
connection is closed if there is no incoming or outgoing data through the serial port for the
specified Inactivity time. If this field is set to 0, the TCP connection is kept active until a
connection close request is received.
.
ATTENTION
Inactivity time should at least be set larger than that of Force transmit time. To prevent the
unintended loss of data due to the session being disconnected, it is highly recommended that this
value is set large enough such that the intended data transfer is completed.
Auto-Link Protocol: If this field is set to None, the NPort 6000 will not connect to the host
automatically. If Auto-Link Protocol is set to Telnet or Rlogin, the NPort 6000 will connect to the
host automatically using the specified protocol.
Primary and Secondary host address: If specified, the fields designate permanent hosts to which
the terminal will always be connected.
Telnet TCP port (default=23): By default, the Telnet TCP port number is set to 23, which is the
default TCP port number for Telnet.
Terminal type (default=ansi): Some older terminal applications may require that the terminal type
be transmitted before the connection can be established. You may need to refer to the server’s
documentation to determine the appropriate terminal type. For most applications, this setting will
be unnecessary and will have no effect
Max. Sessions (default=4): This setting allows you to configure the maximum. number of sessions
allowed for the serial port.
