Just a quick overview over a couple of cisco hidden command useful in certain circumstances
ttcp is only available on routers/layer 3 switches (of course ;-) )
For those familiar with iperf, ttcp is a kinda”ish” iperf
Start ttcp on one router in point 2 point scenario and ttcp on the other endpoint. One router will be in receiving mode, while the other will be in sending mode… running the command is quite straight forward, thus I will not demonstrate it here.
