Usage Information
You can configure the amount of time for which the device must wait before it attempts to establish a TCP
connection. Using this capability, you can limit the wait times for TCP connection requests. Upon responding to the
initial SYN packet that requests a connection to the router for a specific service (such as SSH or BGP) with a SYN
ACK, the router waits for a period of time for the ACK packet to be sent from the requesting host that will
establish the TCP connection.
