Understanding Best Practices
Here is a list of best practices related to OpenManage Network Manager (OMNM) installation.
Ports Used
The OpenManage Network Manager (OMNM) application uses the following ports. Make sure
that your firewalls or other network security measures do not block these ports.
The client HTTP cut-through goes directly to the device from the client. So, you must get to
devices through port 8080 to cut-through to the embedded Web server. Telnet cut-through goes
directly to the Application server as a proxy on ports 6500-6510.
The following ports are seldom required, but are listed here in case present or future functionality
requires them:
