Usage
guidelines
If there is SYN attack in the network, reducing the SYN
timeout value can prevent resource consumption, but it
takes no effect to the successive SYN attacks. When the
device actively request for the connection with the
external, reducing the SYN timeout value can shorten
the time for the user to wait, such as telnet. For the bad
network, the timeout value can be increased properly.
Examples
Ruijie(config)# ip tcp syntime-out 10
