Which ports does WBEM require?

WBEM, which stands for Web-Based Enterprise Management, is a standard that allows for the management of networked devices and systems over the internet. It specifically utilizes the Common Information Model (CIM) to facilitate interactions between different systems and components.

The correct answer regarding the ports that WBEM requires is based on its defined standards for communication. WBEM typically operates over the Hypertext Transfer Protocol (HTTP) and Secure HTTP (HTTPS), using the ports 5988 for HTTP communication and 5989 for HTTPS communication. These ports were chosen to avoid conflicts with the traditionally used web server ports (80 for HTTP and 443 for HTTPS), which are typically assigned to general web traffic.

Recognizing the specific ports associated with WBEM is crucial for setting up the discovery process in ServiceNow Discovery, as using the correct ports ensures successful communication with devices that implement WBEM-based management interfaces. Understanding these ports will also help in configuring network firewalls and ensuring all necessary communications are allowed for effective system monitoring and management.
