I have a customer with a publisher, two subscribers, and an emergency responder server. Subscriber number 2 had an IP of 10.21.29.100, but it was moved to another subnet recently and the IP was changed to 10.16.29.100. The new IP is configured in the SNMP settings on the CER server. I do not see the old IP in the lmhosts or hosts files and the customer's DNS/WINS servers do not have this IP associated to the server name. However, we keep getting the following email notification: CER Phone Tracking could not get information[using SNMP] from 1 Cisco CallManager(s)
Check EventViewer on CERServer for details. When we check the event viewer it shows the following: failed to retrieve SysOid of a device 10.21.29.100. Does anyone know where the CER server could be getting this IP from?
