If fact, you don't have to ping from both sides since when you ping a machine, it is expected that it will answer back else the machine is down/unreachable. Now, this might not be a cure it all. I can't be positively sure but I suspect that entries are periodically flushed from the forwarding table after behing "idle" for some times, as ARP entries. So, a periodic ping between the two machines should do, unless there is a way to "statically" populate the switch forwarding table. > Thanks for that elaborate explanation. You're welcome.
