Weeding through the stream in wireshark doesn't sound that bad. You'd
want to generate 1000pps to get 1ms accuracy though

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

Subject: Re: [AFMUG] Failover / Recovery Time Testing?
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 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

Subject: [AFMUG] Failover / Recovery Time Testing?
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
