Usage Information You can congure 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 specic 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.
show ip tcp initial-time
Displays the interval that you congured for the device to wait before the TCP connection is attempted to be established.
