Specifying a flow log export destination

You can export flow log entries to a log host or the information center, but not both. If you configure both
methods, the system exports flow log entries to the information center.
• If the destination is a log host, flow log entries are sent as binary characters in UDP. One UDP
packet can contain multiple log entries.
If the destination is the information center, flow log entries are converted to syslog entries in ASCII
•
format, with the informational severity level. With the information center, you can specify multiple
output destinations, including the console, log host, and log file. For more information about the
information center, see "Configuring the information center."
Log entries in ASCII format are human readable. However, the log data volume is higher in ASCII format
than in binary format.
