Ping something that gives you <1mS pings then fail the circuit over and see what the ping time is on the next ping.

I want to use a tool that will time the "outage" automatically. For example, switches with ERPS capability usually claim things like "sub 50ms recovery". How can I time that recovery on my actual system? I picture running some continuous data stream between two points, and measuring any gaps in received data... but automatically instead of weeding through the stream in wireshark. -------------------------------------------------------------------------------- On Mon, Jan 29, 2018 at 9:46 AM, Faisal Imtiaz <[email protected]> wrote: Not sure what exactly are you asking about ? How to break stuff ? and or How to know when it is fixes ? On a serious note, it depends on what you are testing.. e.g. one can easily simulate OSPF failover by turning a link / ethernet / radio port off.. and watching a traceroute (MTR or Pathping, Pingplotter etc etc ) and or watching the Router Logs Regards.

What tools do you suggest for testing failover time / recovery time? I've got several different failover mechanisms in use, and I'd like to start empirically testing them to have a better sense of their performance. Thank you - Chris
