Parameters

vpn-instance vpn-instance-name: Specifies a VPN by its name, a case-sensitive string of 1 to 31

characters. If the flow logging server is on the public network, do not specify this option.

ipv6-address: Specifies the IPv6 address of the flow logging server.

udp-port: Specifies the UDP port number of the flow logging server, in the range of 0 to 65535.

Usage guidelines

To output flow logs in UDP packets to a server, you must specify the server. Otherwise flow logs cannot

be exported.

To avoid collision with general UDP port numbers, use UDP port numbers in the range of 1025 to 65535.

The specified VPN instance must have been created. Otherwise packets delivery fails.

You can specify at most two log servers of the same type or different types for a device. There are three

types of log servers, the VPN flow logging server, the IPv4 flow logging server, and the IPv6 flow logging

server. If you have already specified two servers, you need to delete one to specify a new one. If you

specify a new server that has the same IP address as but has other information different from the current
