NetStream Configuration Commands

NetStream Configuration Commands

NOTE:

The NetStream function conforms to IETF RFC3954. For security risks, see IETF RFC3954. This function involves analyzing the communications information of terminal customers. Before enabling the function, ensure that it is performed within the boundaries permitted by applicable laws and regulations. Effective measures must be taken to ensure that information is securely protected.

Command Support

NetStream is only supported by E series cards (except ET1D2X48SEC0 card) and X series cards.

collect counter

Function

The collect counter command allows the flexible flow statistics exported to the NetStream Collector (NSC) to contain the number of bytes and packets.

The undo collect counter command restores the default setting.

By default, the flexible flow statistics exported to the NSC do not contain the number of bytes or packets.

Format

collect counter { bytes | packets }

undo collect counter { bytes | packets }

Parameters

Parameter

Description

Value

bytes

Indicates that the flexible flow statistics exported to NSC contain the number of bytes.

Description

Value

version

Specifies the version number of exported packets carrying aggregation flow statistics.

The value of version is set to 8 or 9. The default is 8.

Views

NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

The NDE exports NetStream flow statistics to the NSC. The version of exported packets must be the same as that configured on the NSC so that the NSC can parse the exported packets.

The format of exported packets in V8 is fixed and is not easy to expand. The format of exported packets in V9 is defined in templates and is easy to combine or expand. The statistics are exported more flexibly.

V9 is supported by most NSCs for its advantages. It is recommended that you set the version of exported packets carrying aggregation flow statistics to V9.

Example

# Set the version number of exported packets carrying aggregation flow statistics to V9.

<HUAWEI> system-view
[HUAWEI] ip netstream aggregation as

Format

ip netstream { inbound | outbound }

undo ip netstream { inbound | outbound }

Parameters

Parameter

Description

Value

inbound

Enables flow statistics collection on the inbound interface.

-

outbound

Enables flow statistics collection on the outbound interface.

-

Views

GE interface view, XGE interface view, 40GE interface view, 100GE interface view, port group view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

To export IPv4 flow statistics, you must run the ip netstream command to enable the IPv4 flow statistics collection function on the interface.

Precautions

  • When the IPv4 and IPv6 flow statistics collection function is enabled on the interface, statistics about unicast and multicast packets are collected.
  • After the statistics collection function is enabled for IPv4 and IPv6 flows, the statistics are independent of each other.
  • Currently, the flow statistics collection function can be enabled only on the main interface. If the NetStream function is enabled on the main interface but you do not set a sampling ratio using the ip netstream sampler command, the main interface uses the sampling ratio of 1:1000. If you set the sampling ratio, the interface uses this sampling ratio.

Example

# Enable the flow statistics collection function for the incoming IPv4 packets on GE1/0/1.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

NetStream aggregation groups the original flows with the same attributes together. The aggregation flow statistics collection and original flow statistics collection are different. The original flow statistics collection is on the basis of sampled packets, while the aggregation flow statistics collection is on the basis of original flows. Therefore, the aggregation flow statistics collection generates less data.

Follow-up Procedure

Run the enable command in the aggregation view to enable the device to export flow statistics according to the configured aggregation method.

Example

# Configure the NetStream AS aggregation method.

<HUAWEI> system-view
[HUAWEI] ip netstream aggregation as
[HUAWEI-aggregation-as]

# Configure the NetStream destination-prefix aggregation method.

<HUAWEI> system-view
[HUAWEI] ip netstream aggregation destination-prefix

ip netstream export host

Function

The ip netstream export host command configures the destination IP address and destination UDP port number for the exported packets carrying IPv4 flow statistics.

The undo ip netstream export host command deletes the configured destination IP address and destination UDP port number for the exported packets carrying IPv4 flow statistics.

By default, no destination IP address and destination UDP port number are configured in the system view or aggregation view for the exported packets carrying IPv4 flow statistics.

Format

ip netstream export host ip-address port-number

undo ip netstream export host ip-address port-number

Parameters

Parameter

Description

Value

ip-address Specifies the destination IPv4 address of the exported packets carrying IPv4 flow statistics.

-

port-number Specifies the destination UDP port number of the exported packets carrying IPv4 flow statistics.

The value is an integer that ranges from 1 to 65535.

Views

System view, NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

After finishing data collection, the NDE sends the collected data to the NSC. This command specifies the destination address of the collected data, that is, the NSC IP address.

Precautions

When you run the ip netstream export host command in the system view, this command configures the destination address for the exported packets carrying IPv4 original flow statistics and IPv4 flexible flow statistics; when you run this command in the aggregation view, this command configures the destination address for the exported packets carrying IPv4 aggregation flows. The exported packets carrying aggregation flow statistics preferentially use the destination address configured in the aggregation view. If the destination address is not configured in the aggregation view, the exported packets carrying aggregation flow statistics use the destination address configured in the system view.

You can configure two destination addresses in the system view or aggregation view to implement NSC backup. To configure a third destination IP address, run the undo netstream export ip host command to delete an existing one first; otherwise, the system displays a message indicating that the maximum number of addresses is exceeded and the configuration fails.

Example

# Set the destination IP address for the exported packets carrying original flow statistics to 10.1.1.1, and UDP port number to 222.

<HUAWEI> system-view
[HUAWEI] ip netstream export host 10.1.1.1 222

# Set the destination IP address for the exported packets carrying aggregation flow statistics to 10.2.2.1, and UDP port number to 255.

ip netstream export index-switch

Function

The ip netstream export index-switch command sets the number of digits in the interface index contained in an exported packet carrying IPv4 flow statistics.

By default, the number of digits in interface indexes is 16..

Format

ip netstream export index-switch index-switch

undo ip netstream export index-switch

Parameters

Parameter

Description

Value

index-switch

Specifies the number of digits in the index of a specified interface.

The value is 16 or 32. The default value is 16.

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

You can run the ip netstream export index-switch command to set the number of digits in the interface index to 16 or 32.

The number of digits in an interface index contained in exported packets must be the same as the number of digits in an interface index that can be parsed by the NMS. For example, if the NMS can parse the 32-digit interface index, set the number of digits in an interface index contained in exported packets to 32.

Precautions

The number of digits in the interface index can be changed to 32 only when the NMS supports 32-digit interface index. If the number of digits in an interface index contained in exported packets is different from the number of digits in an interface index supported by the NMS, the NMS cannot identify NetStream packets sent by the device.

This command is valid for V9. Before changing 16-digit interface indexes to 32-digit interface indexes, ensure that:

  • The version of exported packets of original flows is V9.
  • The version of exported packets carrying aggregation flow statistics is V9.

When the 32-digit interface index is used, the version of exported packets of original flows cannot be changed from V9 to V5, and the version of exported packets carrying aggregation flow statistics cannot be changed from V9 to V8.

Example

# Change the number of digits in the interface index contained in an exported packet carrying IPv4 flow statistics from 16 to 32.

ip netstream export source

Function

The ip netstream export source command configures the source address for the exported packets carrying IPv4 flow statistics.

The undo ip netstream export source command deletes the configured source address for the exported packets carrying IPv4 flow statistics.

By default, no source address is configured in the system view or aggregation view for the exported packets carrying IPv4 flow statistics.

Format

ip netstream export source ip-address

undo ip netstream export source

Parameters

Parameter

Description

Value

ip-address

Specifies the source IPv4 address of the exported packets carrying IPv4 flow statistics.

The parameter must be set to an existing IP address on the device.

Views

System view, NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

If the NMS identifies the data source according to the source IP address in NetStream packets, you need to specify the source IP address for NetStream packets.

Precautions

NetStream prefers the source IP address configured in the aggregation view. If no source address is specified in an aggregation method, the source address configured in the system view is used.

This command must be performed; otherwise, the source address of output packets may be 0.0.0.0, and the output packets may be discarded during transmission or cannot be parsed by the NetStream server.

Example

# In the system view, set the source address for the exported packets carrying IPv4 flow statistics to 10.1.1.1.

<HUAWEI> system-view
[HUAWEI] ip netstream export source 10.1.1.1

# In the aggregation view, set the source address for the exported packets carrying IPv4 flow statistics to 10.2.2.2.

3: Management level

Usage Guidelines

Usage Scenario

The NDE exports NetStream flow statistics to the NSC. The version of exported packets must be the same as that configured on the NSC so that the NSC can parse the exported packets.

The format of exported packets in V5 is fixed and is not easy to expand. The format of exported packets in V9 is defined in templates and is easy to combine or expand. The statistics are exported more flexibly.

V9 is supported by most NSCs for its advantages. It is recommended that you set the version of exported packets carrying aggregation flow statistics to V9.

Precautions

Only one version can be specified on a device. The versions configured on all the devices on the network must be the same as the version configured on the NMS.

The AS option is used according to the actual situation of the AS configured on each device. The AS option affects only the packet statistics result, but does not affect the flows. The AS option is encapsulated in the AS option field carried in the NetStream packets sent to the NMS.

Example

# Set the version of the exported packets carrying IPv4 flow statistics to V9 and AS option to peer-as.

-

Views

GE interface view, XGE interface view, 40GE interface view, 100GE interface view, port group view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

The suppression ratio is used during traffic sampling. When a little traffic exists on the network, sampling is unnecessary. After a suppression ratio is configured, the device does not create a flow table when traffic volume is smaller than the suppression ratio. For example, if the suppression ratio is set to 2000, the device does not create a flow table when the number of packets in a flow is smaller than 2000 and creates a flow table when the number of packets in a flow exceeds 2000.

Precautions

The suppression ratio takes effect only on an interface. Currently, up to three suppression ratios can be set on each board of the device.

You must run the ip netstream suppress command together with the ip netstream and ipv6 netstream commands. If you run only the ip netstream suppress command, the command does not take effect.

If you run the ip netstream suppress command multiple times in the same interface, only the latest configuration takes effect.

The ip netstream suppress and ip netstream sampler commands are independent of each other.

Example

# Set the suppression ratio of the incoming traffic on GE1/0/1 to 2000.

ip netstream tcp-flag enable

Function

The ip netstream tcp-flag enable command configures the aging of NetStream traffic according to the FIN flag or the RST flag in the TCP packet header.

The undo ip netstream tcp-flag enable command restores the default setting.

By default, NetStream flows are not aged according to the FIN or RST flag in the TCP packet header.

Format

ip netstream tcp-flag enable

undo ip netstream tcp-flag enable

Parameters

None

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

The FIN or RST flag in a TCP packet indicates that the TCP connection is terminated. When receiving a packet with the FIN or RST flag, the device immediately ages the corresponding NetStream flow. If the ip netstream tcp-flag enable command is not run, NetStream flows are aged by following other criteria, for example, inactive aging time or bytes overflow.

Precautions

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

Only original flows can be aged according to the FIN or RST flag in the TCP packet header.

Example

# Configure the aging of original flows according to the FIN or RST flag in the TCP packet header.

Format

ip netstream timeout active active-interval

undo ip netstream timeout active

Parameters

Parameter Description Value
active-interval

Specifies the active aging time.

The value is an integer that ranges from 1 to 300, in seconds. The default is 200.

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

Network traffic may burst intermittently, while the memory capacity of the NDE is limited. Earlier flows in the memory need to be exported to release space for the new flows. The process of exporting old flows is called aging. All flows in the NDE memory will be exported to the NSC for analysis.

When the active time (from flow creation time to the current time) of a flow exceeds the specified active aging time, the flow is exported to the destination.

To quickly detect the status of an active flow, set the active time to a small value; however, this setting increases the frequency at which NetStream packets are sent. To reduce the frequency at which NetStream packets are exported and improve statistics collecting efficiency, set the active time to a large value.

Precautions

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

Only X series cards support this command. When you execute this command on a device with other cards installed, the system displays a message similar to: Current board <4,6,8,9,10> do not support this command. 4,6,8,9,10 indicates the slot IDs of the cards that do not support this command.

Example

# Set the active aging time to 240 seconds.

Usage Scenario

Network traffic may burst intermittently, while the memory capacity of the NDE is limited. Earlier flows in the memory need to be exported to release space for the new flows. The process of exporting old flows is called aging. All flows in the NDE memory will be exported to the NSC for analysis.

When the inactive time (from the last packet receiving time to the current time) of an original or flexible flow exceeds the specified inactive aging time, the flow is exported to the destination.

To quickly detect the status of an inactive flow, set the inactive time to a small value; however, this setting increases the frequency at which NetStream packets are sent. To reduce the frequency at which NetStream packets are exported and improve statistics collecting efficiency, set the inactive time to a large value.

Precautions

The inactive aging time that is configured using the ip netstream timeout inactive command applies to both IPv4 and IPv6 flows.

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

Usage Guidelines

Usage Scenario

To export IPv6 flow statistics, you must run the ipv6 netstream command to enable IPv6 flow statistics collection on the inbound interface.

Precautions

  • When the IPv4 and IPv6 flow statistics collection function is enabled on the interface, statistics about unicast and multicast packets are collected.
  • After the statistics collection function is enabled for IPv4 and IPv6 flows, the statistics are independent of each other.
  • Currently, flow statistics collection can be enabled only on main interfaces. If statistics collection is enabled on an interface but you do not set a sampling ratio using the ipv6 netstream sampler command, the interface uses the sampling ratio of 1:1000. If you have set the sampling ratio, the interface uses this sampling ratio.

Example

# Enable statistics collection for the incoming IPv6 flows on GE1/0/1.

Usage Guidelines

Usage Scenario

After finishing data collection, the NDE sends the collected data to the NSC. This command specifies the destination address of the collected data, that is, the NSC IP address.

Precautions

The netstream export ipv6 host command configures the destination address for the exported packets carrying IPv6 original flows and flexible flows.

You can configure two destination IP addresses to implement NSC backup. To configure a third destination IP address, run the undo ipv6 netstream export host command to delete an existing one first; otherwise, the system displays a message indicating that the maximum number of addresses is exceeded and the configuration fails.

Example

# Set the destination IP address for the exported packets carrying IPv6 original flows to 10.1.1.1, and UDP port number to 222.

Usage Guidelines

Usage Scenario

After a flexible flow statistics template is configured, run the port ip netstream record command to apply the template to an interface.

The interface then aggregates flows based on the configured aggregation keywords, collects flow statistics, and exports aged flows to the NSC.

Prerequisites

A flexible flow statistics template has been created using the ip netstream record command, and at least one aggregation keyword has been configured using the match (Flexible Flow Statistics Template View) command.

Precautions

  • If the vlan parameter is configured in the flexible flow statistics template, it is recommended that the template be applied to Layer 2 Ethernet interfaces.
  • If the input parameter is configured in the flexible flow statistics template, the template can be applied only to the inbound direction of an interface. If the output parameter is configured in the flexible flow statistics template, the template can be applied only to the outbound direction of an interface.
  • The flexible flow statistics template that has been applied to an interface cannot be modified or deleted. Run the undo port ip netstream record command to unbind a specified flexible flow statistics template from the interface, and then you can modify or delete the template.
  • Only one flexible flow statistics template can be applied to each interface in the inbound or outbound direction, and the template can be the same or different. To change the flexible flow statistics template, run the undo port ip netstream record command to delete the existing template.

Usage Guidelines

When IPv4 aggregation flow statistics is exported in NetStream V9, the NetStream server can parse the exported packets in V9 only after receiving the NetStream export template from the switch.
