Telnet Time-Out is killing me….

Aaarrrgggghhh, I hate it when I would like to telnet into a device and enter the wrong IP address. This means, by default, waiting for 30 seconds before being able to correct the IP address and start a new telnet session, because there is no escape sequence.

SW01#telnet 10.100.12.250
Trying 10.100.12.250 …
% Connection timed out; remote host not responding

Luckily there is a command to lessen the time for timing out the connection:

SW01(config)# ip tcp synwait-time <seconds>       (Set time to wait on new TCP connections)

Hoera, tcp synwaiting saves the day….
