Sorry to drag up an old thread, but I'm curious about this one. I have just
ran across this exact same ping symptoms as shown below - four successful
pings followed by one fail. I can replicate this on four separate clusters
100% of the time. In all cases I was pinging the CUCM from the default
gateway (Catalyst switch). Is this expected behavior?
