Debug port interfaces - open-switch/opx-docs GitHub Wiki

During system startup, physical ports map to Linux network interfaces. See Physical ports in Interfaces for naming convention information for Linux network interfaces.

Troubleshoot interfaces

• If Linux network interfaces are not created:

  – Check that the NAS process is running, and check the /var/log/syslog file for errors

  – If the NAS is not running, check if other processes on which NAS depends are running

• If physical port interfaces are not enabled (administratively up) in the NPU, check that the SAI/NPU SDK has initialized correctly. You can also use the journalctl utility.
