Troubleshooting flow logging
Symptom 1: No flow log is exported
• Analysis: No export approach is specified.
• Solution: Configure flow logging to export flow logs to the information center or to the log server.
Symptom 2: Flow logs cannot be exported to log server
• Analysis: Both of the export approaches are configured.
• Solution: Restore to the default, and then configure the IP address and UDP port number of the log
server.
