Both can be used at the same time. SNMP normally uses UDP port 161 for requests, and sends on port 162 for traps. SNMP use seems to be deprecated by MS, so third party products have to fill in here, e.g. SNMP Informant.
MS much prefers WMI for system monitoring. The WMI ports will only need to be opened if you are using the WMI Zenpack. If you do need them, firstly know that WMI runs over DCOM, see here ( http://msdn.microsoft.com/en-us/library/ms809327.aspx). Generally the client will connect on Port 135, then the actual protocol in use will choose a random port from 1024 up to have the conversation on. You can configure If your environment is locked tight so that ports aren't generally opened, you might have some difficulty using WMI. -- Regards, Graham Bloice
