• To avoid collision with general UDP port numbers, UDP port numbers in the range 1025 to 65535
are recommended.
• The specified VPN instance should be created, otherwise packets delivery fails.
• You can select at most two log servers from three types of log servers (which are flow logging server
in a VPN, IPv4 flow logging server) to receive flow logs for each device. If you specify two log
servers for a device, the servers can be of the same type or of different types. If you have already
specified two servers, you need to delete an existing one to specify a new one. If in a new
configuration, the IP address is the same with that of the currently effective configuration, but other
information of the two configurations is different, then the new configuration will overwrite the
previous one.
