Troubleshooting

Troubleshooting may be required to identify and correct problem situations when the Nokia community SONiC system is not operating normally.

Troubleshooting includes identifying the symptoms of a problem, detecting the fault that caused it, and correcting the fault.

Before contacting the Nokia technical support service for assistance with troubleshooting, use the show techsupport CLI command to collect diagnostic information about the device.

This command gathers information such as syslog entries, database state, and routing-stack state, and then compresses it into an archive file. The system saves the archive as /var/dump/<DEVICE_HOST_NAME>_YYYYMMDD_HHMMSS.tar.gz. Provide this information when you contact Nokia technical support.

admin@sonic:~$ show techsupport [--since=<time_specifier>]

See the SONiC documentation at the SONiC GitHub for more information about troubleshooting community SONiC.
