I'm having trouble with false alarms on Cisco switches. Running Server's Alive Enterprise version 7.2.2638 on Windows 7. Periodically, several switches show as down. Looking at the logs, I'm seeing ping return rates of 40%, 20%, etc. These false alarms don't affect anything else that I'm monitoring, such as servers. Only switches. Then in the next cycle, they'll show as up. It's not the same switches each time. There appears to be no rhyme or reason as to which switches will alarm. It doesn't appear to be hardware related (workstation NIC or network port); otherwise other equipment would alarm as well. It doesn't appear to be the specific alarming switches as the list changes seemingly at random and if I set up a "ping -t <ip-address>" on the same workstation, nothing appears to drop.
In the registry I noticed a key labeled "Ping". Within it is a key labeled "UseMultiPing", which for me is currently set to 1. I can't find documentation on this key, but was wondering of someone could explain how MultiPing works. Also, what would be the effects of changing this key or possibly adding other keys that I don't know about. This situation has my admins concerned because monitored equipment is not down, but appears to be. Any thoughts or ideas would be appreciated. Thanks.
