PowerFlex Required Ports and Protocols

Summary: PowerFlex Security Configuration Guide documentation may not accurately list all requires ports and protocols for PowerFlex Manager functionality. An updated table has been provided in this article to highlight all requirements. ...

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Instructions

PowerFlex environments where firewalls are used may encounter various failures related to network/port connectivity during normal operations.

Multiple ports that are required for standard operation are still blocked after following documentation to open all required ports.

 

Impact

Various operations may be impacted such as node expansions, upgrades, and deployments. 

Cause

The PowerFlex Security Configuration Guide does not reflect all required network ports and protocols for PowerFlex Manager operation.

Resolution

 

The Security Configuration Guide will be updated for PowerFlex 4.8 to reflect the expanded requirements.

 

Refer to the following table and ensure all listed ports/protocols are open within the PFMP and PowerFlex environment:
