OCP Network Prerequisites

Portworx network requirements

Portworx runs as a pod in a Kubernetes cluster and uses specific ports for communication, data transfer, and telemetry.

East-to-west

note

• Portworx also requires the following ports:
  • An open KVDB port. For example, if you're using etcd externally, open port 2379.
  • An open UDP port at 9002.
• For telemetry, open ports 9024, 12001, and 12002. Ensure you are running Portworx Operator version 23.7.0 or higher to configure the telemetry port:
  • Portworx Versions 2.13.7 and Older: Open port 9024 specifically for telemetry.
  • Portworx Versions 2.13.8 and Newer: Use port 9029 for telemetry.
