The server establishes a TCP connection and enters ESTABLISHED state only when it receives an ACK packet from the sender. Examples # Enable SYN Cookie. system-view [Sysname] tcp syn-cookie enable tcp timer fin-timeout Use tcp timer fin-timeout to configure the TCP FIN wait timer. Use undo tcp timer fin-timeout to restore the default. Syntax tcp timer fin-timeout time-value undo tcp timer fin-timeout Default The TCP FIN wait timer is 675 seconds. Views System view Predefined user roles network-admin 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 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 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. system-view [Sysname] tcp timer fin-timeout 800 tcp timer syn-timeout Use tcp timer syn-timeout to configure the TCP SYN wait timer. Use undo tcp timer syn-timeout to restore the default. Syntax tcp timer syn-timeout time-value undo tcp timer syn-timeout 145
