I am using IPM 2.5 and am trying to creare several collectors that us the defaultUDP echo operation. I have checked the routers that I am using and they have either IPSLA running or thr rtr responder statement in the router. Once I try to creat the collector it states that RTR must be running but it is already. What am I missing? The IOS versions are all over the 12.1 ver so that is not an issue. Any suggestions??
