UDP Port 161 for General SNMP and 162 for SNMP Traps. OMSA requires Port 1311

Dell OpenManage Server Administrator. OMSA is Web based and uses TCP port 1311 to communicate via HTTP. The traffic on TCP port 1311 is encrypted by128-bit Secure Sockets Layer (SSL). To help ensure that OMSA is usable on the managed server, administrators should allow HTTP over SSL (HTTPS) and HTTP traffic to port 1311.

SNMP port 25
SNMP = SIMPLE NETWORK MANAGEMENT PROTOCOL - this is a set of standards that most computer equipment follow that allows you to setup monitors on the devices to tell you things such as: powered on, powered off, faulty hardware, low disk space, low memory, low paper for printers, etc.

Hmm.. strange. We have a lot of servers with OMSA in the same network as the ITA - works fine. Then some servers in a DMZ - no connection - even if 161 and 162 are open.
I have an idea that even the side-by-side servers are not using SNMP because I have never configured that on any server. Instead I have seen "green lights" because ITA have used CIM instead (RPC port 135) - does that make sence?

Hi again.
Sorry for my absence during the holidays...

Anyways I'm now able to be more specific:
I've managed to get basic communication running to all servers (after allowing SNMP 161/162 and after configuring the servers talking SNMP to the management station) - green lights in ITA.
Now the only problem is to get "Performance Monitoring" to work in ITA against the servers in the DMZ. I need to check the disk space on these servers. ITA reports error in SSH/CIM communication when performing these tests. As if this cannot be done through SNMP? Is this possible and if not can CIM be routed and through which ports?
