1 Cisco rtr being automatically picked up as many devices

Question - any one else being slammed by the eventlog analyzer automatically picking up one single Cisco Router as multiple servers, based on the internal IP of various interfaces??? i.e. I ADD a Cisco dev, using it's local ethernet IP as the host name (so I can tell what it is by it's local IP scheme). HOWEVER, after some time passes, several other servers automatically appear in the list of active hosts, with IP hostnames of internal interfaces on routers that were already put in manually. If an ISDN interface on a router goes active, the eventloganlyzer picks that up as a separate server. The result is a multitude of servers in there, all with internal IPs as names, effectively representing only 1 router. This is bogus, and, ultimately, causes out licensing to be exceeded.

Thanks,

Jay
