Answer

No, it is not recommended due to following reasons:

  • Operational Impact
  • The system will operate, but high NFS/data traffic can cause management access (SSH/HTTPS) to become slow or unstable.
  • Availability / Security / Performance
  • Availability: Management access may degrade under data load or network congestion.
  • Security: Management services become exposed on the data network, reducing security.
  • Performance: Data and management traffic share bandwidth, causing mutual impact.
  • Operations: Troubleshooting and daily administrative tasks become more difficult if management access slows down.
  • Risks
  • Loss or degradation of management access during peak data usage.
  • Increased exposure of management interfaces to non‑management networks.
  • Harder system administration when performance or network issues occur.
  • Limitations
  • No features are explicitly disabled.
  • However, using a shared LIF/port prevents meeting best practices for security, availability, and operational separation.
  • Support Considerations
  • This configuration is not recommended.
  • NetApp Support is available, but during troubleshooting customers may be asked to separate data and management LIFs.
  • Why Separate LIFs/ports Are Preferred
  • Dedicated LIFs/ports improve availability, security, and operational stability. 
  • Shared LIFs/ports increase operational risk and reduce security and reliability.
