What is mdix?
This read-only enumeration (na, mdi, or mdi-x) reports whether this Ethernet port on the RAy3 is operating in straight MDI or crossed MDI-X mode. It's mainly diagnostic — with autonego enabled the port typically negotiates this automatically, but an admin can check it when troubleshooting a cabling issue.
