Parameters
time-value: Specifies the TCP FIN wait timer in the range of 76 to 3600 seconds.
Usage guidelines
TCP starts the FIN wait timer when the state of a TCP connection changes to FIN_WAIT_2. If no FIN packet is received within the timer interval, the TCP connection is terminated.
If a FIN packet is received, TCP changes the connection state to TIME_WAIT. If a non-FIN packet is received, TCP restarts the timer and tears down the connection when the timer expires.
Examples
# Set the TCP FIN wait timer to 800 seconds.
