Hi All：
When we installed OME 2.3 in the environment and Through SNMP+WMI to Discovering and Inventorying for Dell Server(M520),This Server also installed Hyper-V Role , Based on Security considerations , There is a firewall blocking between the OME host and the M520.
We follow the document instructions, Setting Firewall Rule and Open Port TCP 135(RPC_CIM) and UDP 161(SNMP), TCP 443(Https) ,TCP 1311(OMSA) ,
Discovering and Inventorying Failure , Did I miss which ports need to be opened?
