What is nwAppnExtIfDlcType?

This read-only enumeration reports the type of Data Link Control protocol running on this port: llc2(1), sdlc(2), or x25(3). An admin uses it to confirm the port's DLC matches the intended physical medium and attached equipment before troubleshooting higher-layer link problems. Seeing sdlc(2) here on a port meant for a LAN connection would immediately flag a configuration mismatch to investigate.

Examples
