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.
