TCP Alive Check Time
Default 7 min
Options 0 to 99 min
Description This field specifies how long the NPort will wait for a response to “keep-alive” packets
before closing the TCP connection. The NPort checks connection status by sending periodic
“keep-alive” packets.
0: The TCP connection will remain open even if there is no response to the “keep-alive”
packets.
1 to 99: If the remote host does not respond to the packet within the specified time, the
NPort will force the existing TCP connection to close.
