8 KB by default.
Configuring TCP timers
You can configure the following TCP timers:
• synwait timer: When sending a SYN packet, TCP starts the synwait timer. If no response packet is
received within the synwait timer interval, the TCP connection cannot be created.
• finwait timer: When a TCP connection is changed into FIN_WAIT_2 state, the finwait timer is
started. If no FIN packet is received within the timer interval, the TCP connection is terminated. If a
FIN packet is received, the TCP connection state changes to TIME_WAIT. If a non-FIN packet is
received, the system restarts the timer upon receiving the last non-FIN packet. The connection is
broken after the timer expires.
Follow these steps to configure TCP timers:
To do… Use the command… Remarks
Enter system view system-view —
Configure the TCP synwait timer tcp timer syn-timeout time-value
Optional
75 seconds by default.
Configure the TCP finwait timer tcp timer fin-timeout time-value
Optional
675 seconds by default.
CAUTION:
The actual length of the finwait timer is determined by the following formula:
Actual length of the finwait timer = (Configured length of the finwait timer – 75) + configured length of the
synwait timer
