netstream export source

Function

The ip netstream export source command specifies a source IP address and a source port for the output NetStream IPv4 flows.

The undo ip netstream export source command deletes the source IP address and source port configured for the output NetStream IPv4 flows.

The ipv6 netstream export source command specifies a source IPv6 address and a source port for the output NetStream IPv6 flows.

The undo ipv6 netstream export source command deletes the source IPv6 address and source port configured for the output NetStream IPv6 flows.

By default, no source address or source port from which NetStream statistics are output is configured.

Format

Parameters

Parameter	Description	Value
port	Specifies the source port of the output NetStream flows.	The value is an integer that ranges from 1 to 65535. The default value is 40000.
ip	Displays the IPv4 netstream feature.	-
ip-address	Specifies the source IP address of the output NetStream flows.	The value is in dotted decimal notation.
ipv6	Displays the IPv6 netstream feature.	-
ipv6 ipv6-address	Specifies the source IPv6 address of the output NetStream flows.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.

Usage Guidelines

Usage Scenario

A NetStream-enabled NMS identifies the NetStream data source based on the source IP address and the source port carried in NetStream flows. To configure the source IP address and the source port for the output NetStream flows, run the command. The type of the source IP address configured for output NetStream flows must be the same as the NMS address type. The address type can be either IPv4 or IPv6.

Precautions

The source IP address and the source port configured in the aggregation view take precedence over that configured in the system view. If no source IP address and source port are configured in the aggregation view, the source IP address and the source port configured in the system view are used.

If the source IP address is not configured, no NetStream flow will be output.

Two source IP addresses (one IPv4 address and one IPv6 address) can be configured in the system, monitor or NetStream aggregation view. The two source IP addresses are independent of each other, without causing any conflict.

In the system view, you can configure a source address for original, aggregated, and flexible flows. In the aggregation view, you can configure a source address for aggregated flows. In the monitoring view, you can configure a source address for flexible and original flows.

The specified source address and source port of exported NetStream packets can be precisely deleted only in the monitoring view.

In actual applications, it is recommended that you use the public IP address to configure the source address.

Example

# Set the source IP address to 1.1.1.2 and the number of the source port to 1000 for the output IPv6 aggregated flows.

<HUAWEI> system-view

# Set the source IP address to 1.1.1.2 and the number of the source port to 1000 for the output IPv4 aggregated flows.

<HUAWEI> system-view

<HUAWEI> system-view

# Set the source IP address to 1.1.1.3 and the number of the source port to 1000 for the output IPv4 original flows in the monitoring view.

<HUAWEI> system-view
