Appendix A: DGX OS Connectivity Requirements
In a typical operation, DGX OS runs services to support typical usage of the DGX system.
Some of these services require network communication. The table below describes the port, protocol, direction, and communication purpose for the services. DGX administrators should consider their site-specific access needs and allow or disallow communication with the services as necessary.
This table provides information about the in-band management, storage, and compute networks.
