traffic-analysis udp export host

Function

The traffic-analysis udp export host command configures the destination IP address and destination UDP port number to which the packets carrying intelligent traffic analysis results of UDP flows are sent.

The undo traffic-analysis udp export host command deletes the IPv4 destination address to which the packets carrying intelligent traffic analysis results of UDP flows are sent.

The undo traffic-analysis udp export host ipv6 command deletes the IPv6 destination address to which the packets carrying intelligent traffic analysis results of UDP flows are sent.

Format

traffic-analysis udp export host { ip ip-address | ipv6 ipv6-address } port-number [ vpn-instance vpn-instance-name ]

undo traffic-analysis udp export host [ ipv6 ]

Parameters

Parameter	Description	Value
ip ip-address	Specifies the destination IPv4 address to which packets are sent for intelligent traffic analysis.	The value is in dotted decimal notation.
ipv6 ipv6-address	Specifies the destination IPv6 address to which packets are sent for intelligent traffic analysis.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
port-number	Specifies the destination UDP port number to which packets are sent for intelligent traffic analysis.	The value is an integer The value is an integer in the range from 1 to 65535.
vpn-instance vpn-instance-name	Specifies the name of a VPN instance of packets to be sent for intelligent traffic analysis.	The value must be the name of an existing VPN instance on the device.

Usage Guidelines

By default, no destination IP address or destination UDP port number is configured for the packets that carry intelligent traffic analysis results of UDP flows.

Usage Scenario

After intelligent traffic analysis for UDP flows is enabled on the device, the flow tables that contain the flow analysis results is first stored in the cache of a device. When the flow tables in the buffer meet the aging conditions, the device exports the flow tables to the specified TDA to process and display the flow information. To configure the destination IP address, that is, TDA's IP address, to which the packets carrying UDP flow analysis results are sent, run the traffic-analysis udp export host command.

Precautions

Either an IPv4 or IPv6 address can be configured in the system view, but the IPv4 and IPv6 addresses cannot be both configured using one command. In addition, only one destination TDA address can be set on a device. If you need to configure a new export IP address, perform the either of the following operations based on the actual scenario:

If the IP address types before and after the modification are the same, such as when IPv4 address A is changed to IPv4 address B or IPv6 address A is changed to IPv6 address B, run the traffic-analysis udp export host { ip ip-address | ipv6 ipv6-address } port-number [ vpn-instance vpn-instance-name ] command to replace an existing IP address.
If the IP address type before the modification is different from that after the modification, such as when IPv4 address A is changed to IPv6 address B or IPv6 address B is changed to IPv4 address A, run the undo traffic-analysis udp export host [ ipv6 ] command to cancel the original destination TDA address, and then run the traffic-analysis udp export host { ip ip-address | ipv6 ipv6-address } port-number [ vpn-instance vpn-instance-name ] command to configure a new destination TDA address.

Example

# Set the destination IP address to 10.3.1.10 and destination UDP port number to 6000 for the packets that carry UDP flow analysis results.
