A Customer monitors servers using Microsoft SCOM. He complains that several times a day SCOM alerts because some servers seem to be unreachable. Sending endless Ping from hosts in the subnet of SCOM to hosts in a servers subnet showed that hundreds of replies were missing during a day. When pinging within the same subnet we didn't see any lost replies. So the losses only occur between different subnets.
The Core consists of two N7k with HSRP for the server vlans. Servers are connected to N5k's
I Couldn't find packet drops nor an increase of error counters on involved interfaces.
Does anybody have an idea how to go on in this case?
