Ruijie RG-WLAN Series Rgos Command Reference

Command Reference TCP Commands
According to RFC1191, after discovering the PMTU, the TCP uses a greater MSS to detect the new
PMTU at a certain interval, which is specified by the parameter age-timer. If the PMTU discovered is
smaller than the MSS negotiated between two ends of the TCP connection, the device will be trying to
discover the greater PMTU at the specified interval untill the PMTU value reaches the MSS or the
user stops this timer. Use the parameter age-timer infinite to stop this timer.

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