I have added a voip monitor to my opmanager system and it appears to have added the correct information into the router. It is monitoring and reporting all the information but it appers to think there is packet loss on it as well.

 

Packet Loss threshold limit violated ( > 1). Packet Loss for router1 to 11.11.11.11 is 6

 

That is alerted over and over and they will clear, then alert all over again.

 

The output from the router shows1 packet loss on the ip SLA but a constant ping never drops. Opmanager has been monitoring the device for 2 years without a single dropped packet. now the IP sla can get one each time?

We are running Opmanager 8811

Cisco IOS Version 12.4(4)XD12 on 7206

 

Any ideas?
