NPort 6000 Series User’s Manual Configuring Serial Port Operation Modes
7-29
Reverse SSH Mode
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 the idle time setting for auto-disconnection. A
setting of 0 min. will cause the port to remain connected even if idle.
TCP port (default=4001): This is the TCP port number assignment for the serial port on the NPort
6000. It is the port number that the serial port uses to listen to connections, and that other devices
must use to contact the serial port. To avoid conflicts with well known TCP ports, the default is set
to 4001.
Each of NPort 6000’s serial ports is mapped to a TCP port. To avoid conflicts with other TCP ports,
set port numbers to 4001 for port 1, 4002 for port 2, etc.
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.
