NPort 6000 Series Configuring Serial Port Operation Modes
7-19
Terminal Applications
Terminal ASCII (TERM_ASC)
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.
Verify the ID against the external server.
- Local authentication is tried first, switching to Local if unsuccessful.
Local - 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.
